Layers and perimeters

<p dir="ltr">3D printers work by laying layer over layer of plastic to create a 3D object. Each new layer must be supported by the one beneath it. If part of your model starts in mid-air and is not supported by anything below, you need to add an additional support structure to ensure a successful print.</p>
<div class="tip-callout">It is worth considering altering the orientation of the model or splitting the model into multiple parts in order to possibly reduce overhangs and consequently the amount of supports generated.</div>
<p dir="ltr">PrusaSlicer can both detect areas that need supports and generate them in these places <strong>automatically</strong>.</p>
<p dir="ltr">You can also set supports manually using:</p>
<ul>
<li dir="ltr"><a href="http://help.prusa3d.com/article/paint-on-supports_168584">Paint on supports</a></li>
<li dir="ltr"><a href="http://help.prusa3d.com/article/modifier-meshes-custom-supports-and-other-magic_114258#custom-supports">Support enforcers and blockers</a></li>
</ul>
<p dir="ltr">Supports can be turned on from the <strong>right panel</strong> or in the <strong>Print settings - Support material - Generate support material</strong>.</p>
<p dir="ltr">There are 3 different Support styles in PrusaSlicer</p>
<ul>
<li dir="ltr">Grid</li>
<li dir="ltr">Snug</li>
<li dir="ltr"><a href="http://help.prusa3d.com/article/organic-supports_480131">Organic</a></li>
</ul>
<p dir="ltr">When the print finishes, depending on the model geometry and material used, the support structure is often easily removable with bare hands. You can use pliers to get a better grip in otherwise hard-to-reach places. A scalpel or a utility knife can also be used to cleanly remove a piece of support that seems to be stuck to the model.</p>
<div class="warning-callout">Pieces of supports can be surprisingly sharp and are sometimes violently ejected in a random direction after removal. When you encounter hard-to-remove supports, <strong>consider wearing protective glasses</strong> (this sounds stupid until you get hit in the eye for the first time).</div>
<h3 dir="ltr">Supports everywhere</h3>
<p dir="ltr">Supports can grow from both the print bed and any model surface when necessary. </p>
<p dir="ltr">This ensures that every overhang and part starting mid-air will get supported. However, small imperfections may appear on the surface where supports started growing from.</p>
<h3 dir="ltr">Supports from build plate only</h3>
<p>Creates only supports that have their base at the print bed.</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/everywhere_build_plate_only.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/everywhere_build_plate_only-300x171.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/everywhere_build_plate_only-600x343.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/everywhere_build_plate_only-768x439.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/everywhere_build_plate_only-800x457.jpg 800w" alt="" /></p>
<p style="text-align: center;"><em>Supports from build plate only (left), supports everywhere (right)</em></p>
<h3 dir="ltr">For support enforcers only</h3>
<p dir="ltr">Automatic support generation is enabled only for areas marked with a support enforcer. This option is essentially a shortcut that turns <strong>Print settings - Support material - Generate support material</strong> on, but <strong>Print settings - Support material - Auto-generated supports</strong> off.</p>
<h3 dir="ltr">Supports on/off for individual models</h3>
<p dir="ltr">It’s possible to print multiple objects at once each with its own support settings. By default, all models are affected by the global settings. You can overwrite them by <strong>right-clicking</strong> on a model in the 3D view and selecting <strong>Support material</strong>. Alternatively, you can right-click on the editing icon in the Object list.</p>
<p dir="ltr">A new window will appear in the right panel called <strong>Object settings to modify - Support material</strong>. Changing these settings will affect only the relevant object and its instances. You can remove the settings overwrite by clicking on the red cross icon. When you do so, the global settings will once again be applied.</p>
<p dir="ltr"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-300x149.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-600x299.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-768x383.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_per_object-2-800x399.png 800w" alt="" width="495" height="247" loading="lazy" /></p>
<h3 dir="ltr">Support enforcer/blocker</h3>
<p dir="ltr">The automatic supports can sometimes appear in hard-to-reach places, resulting in a tedious removal of support structures. If you think such a part of the model could be printed without supports, but neither the <strong>Overhang threshold</strong> setting nor selecting <strong>Supports on built plate only</strong> helped, you can adjust supports manually.</p>
<div class="tip-callout">Starting with PrusaSlicer 2.3, you can also use <a href="http://help.prusa3d.com/article/paint-on-supports_168584">Paint on supports</a>.</div>
<p dir="ltr"><strong>Right-click</strong> on a model and choose either a <strong>Support blocker or Support enforcer</strong>.</p>
<p dir="ltr"><span style="color: #2dc26b;"><strong>Simple mode</strong></span> - Enforcers/blockers are always box-shaped</p>
<p dir="ltr"><span style="color: #f1c40f;"><strong>Advanced mode</strong></span> - Box/Cylinder/Sphere/Slab shapes</p>
<p dir="ltr"><span style="color: #ba372a;"><strong>Expert mode</strong></span> - Option to load external geometry as a blocker/enforcer</p>
<p dir="ltr">Support blockers and enforcers can be manipulated with the familiar Move, Rotate, and Scale tools. You can also quickly duplicate them with copy&amp;paste.</p>
<h3 dir="ltr">Support blocker</h3>
<p dir="ltr">Support blockers are useful when you’re generally happy with the automatic supports and you simply want to remove some of them. Focus on placing blockers where the supports meet the object, the rest of the support structure below will be removed automatically.</p>
<h3 dir="ltr">Support enforcers</h3>
<p dir="ltr">Support enforcers are great in situations, where only a few parts of the object need to be supported, but the automatic algorithm places supports all over the model. In this situation, don’t forget to switch the support mode to For support enforcers only. </p>
<p dir="ltr">It’s less common, but you can also use support enforcers with the automatic generation on.</p>
<p dir="ltr">Another interesting use of support enforcers is to split long bridges into smaller ones by placing a support in the middle of the bridge. You can repeat this process and print shorter, near-perfect bridges while still making the supports easy to remove.</p>
<div class="note-callout">Some options will only appear when <a href="http://help.prusa3d.com/article/simple-advanced-expert-modes_1765">Expert mode</a> is selected.</div>
<h3 dir="ltr"><strong>Generate support material</strong></h3>
<p dir="ltr">Supports are disabled unless a model has an overwrite for this setting</p>
<h3 dir="ltr"><strong>Auto-generated supports</strong></h3>
<p dir="ltr">When off, the overhang detection is off. Only support enforcers generate supports.</p>
<h3 dir="ltr"><strong>Overhang threshold</strong></h3>
<p dir="ltr">The Overhang threshold value represents the most horizontal slope (measured from the horizontal plane) that you can print without support material (90=vertical).</p>
<p dir="ltr">Changing this value is a quick way to adjust the amount of generated supports.</p>
<p dir="ltr">The lower the value, the less support will be generated.</p>

<h3 dir="ltr"><strong>Raft layers</strong></h3>
<p dir="ltr">The object will be raised by this number of layers and support material will be generated under it. When the print finishes, you can grab the raft and peel it away from the part.</p>
<h3 dir="ltr">Raft contact Z distance</h3>
<p>The vertical distance between the raft and the object. Ignored for soluble interfaces.</p>
<h3>Raft expansion</h3>
<p>Expansion of the raft in the XY plane for better stability.</p>
<h3>Style</h3>
<p>Style and shape of supports. The default <strong>Grid</strong> supports have a very well-defined minimum area, making them very stable. However, they tend to leak out of regions they support along the walls of the object. The <strong>Snug</strong> supports maintain the shape of the overhang, so they do not leak to the walls. The trade-off is the possibility of lower stability of tall and thin support pillars.</p>

<p style="text-align: center;"><em>Grid supports (left), Snug supports (right)</em></p>
<p><a href="https://help.prusa3d.com/article/organic-supports_480131"><strong>Organic supports</strong></a> offer a completely different approach to supporting overhanging areas. Branches of support structures grow from the sides and automatically get denser beneath parts that need the support. The Organic supports are easily removable, do not scar the surface, and are fast and cheap to print.</p>
<figure class="image" style="text-align: center;"><img decoding="async" title="Support material" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/07/30cd916294dd7ac737ac7c09e1edfbb9.jpg" alt="" width="2011" height="1119" loading="lazy" /><figcaption>Grid supports (left), Organic supports (right)</figcaption></figure>
<h3 dir="ltr"><strong>Top contact Z distance</strong></h3>
<p dir="ltr">The vertical distance between the object and the support material interface.</p>
<p dir="ltr">Setting this to 0 will prevent PrusaSlicer from using bridge flow and speed for the first object layer.</p>
<p dir="ltr">Values between 50-75% of the layer height seem to work well.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-300x191.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-600x381.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-768x488.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/contact_z_distance-800x508.jpg 800w" alt="" /></p>
<h3 dir="ltr">Bottom contact Z distance</h3>
<p>Similar to Top contact Z distance, but affecting the gap at the bottom of the support tower (when supports start on top of a model and not on the build plate).</p>
<h3 dir="ltr"><strong>Pattern</strong></h3>
<p dir="ltr">Rectilinear - default, usually the easiest to remove</p>
<p dir="ltr">Rectilinear grid - sturdier and less prone to breaking during printing compared to rectilinear infill, harder to remove</p>
<p dir="ltr">Honeycomb - sturdy, somewhat difficult to remove</p>
<h3 dir="ltr"><strong>With sheath around the support</strong></h3>
<p dir="ltr">Creates a single perimeter around the supports, which makes them sturdier, but more difficult to remove.</p>
<h3 dir="ltr"><strong>Pattern spacing</strong></h3>
<p dir="ltr">Spacing between support material lines. Increase to make support removal easier. Support interface layers bridge over support material lines, if you increase this value too much, these bridges will start to sag and have an imperfect connection with the model.</p>
<p dir="ltr">The pattern spacing also sets the internal resolution of PrusaSlicer's supports grid. If you're using Paint-on supports or Support enforcers and you're unable to force supports exactly where you want them to be, try lowering the pattern spacing to get more resolution.</p>
<h3 dir="ltr"><strong>Pattern angle</strong></h3>
<p dir="ltr">Rotates infill pattern angle on the horizontal plane.</p>
<h3 dir="ltr">Closing radius</h3>
<p>For Snug supports only. Gaps smaller than the closing radius will be filled in.</p>
<h3 dir="ltr"><strong>Top interface layers</strong></h3>
<p dir="ltr">Interface layers form a more uniform surface between the object and the support material. These are preferably set to a much denser pattern than the non-interface layers so that you can both maximize the surface area of the support in contact with the model to prevent sagging while minimizing print time and material used with a bigger non-interface pattern spacing.</p>
<h3 dir="ltr">Bottom interface layers</h3>
<p>Similar as Top interface layers, but affecting the number of interface layers at the bottom of the support tower (when supports start on top of a model and not on the build plate).</p>
<h3 dir="ltr"><strong>Interface pattern spacing</strong></h3>
<p dir="ltr">Spacing between interface lines. Set to 0 to get a solid interface.</p>
<h3 dir="ltr"><strong>Interface loops</strong></h3>
<p dir="ltr">When enabled, the top layer of supports is covered with loops - continuous polylines.</p>
<h3 dir="ltr"><strong>Support on build plate only</strong></h3>
<p dir="ltr">Supports can start only on the print bed. Enabling this option is a really quick way to get rid of excess supports mostly on organic shapes. Make sure to check the preview and verify that all parts are either supported or at an overhang angle manageable by the printer.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/supports_build_plate_only.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/supports_build_plate_only-300x178.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_build_plate_only-600x356.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_build_plate_only-768x455.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/supports_build_plate_only-800x474.png 800w" alt="" /></p>
<p dir="ltr" style="text-align: center;"><em>Supports everywhere (left) vs Supports on build plate only (right)</em></p>
<h3 dir="ltr"><strong>XY separation between an object and its support</strong></h3>
<p dir="ltr">Sets the width of a gap between the model and supports. Bigger XY separation decreases the contact area of supports but makes them easier to remove and less prone to fusing to the model.</p>
<p dir="ltr">If expressed as a percentage (for example 150%) it will be calculated over the external perimeter width.</p>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-300x151.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-600x301.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-768x386.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/XY_seperation-1-800x402.jpg 800w" alt="" /></p>
<h3 dir="ltr"><strong>Don’t support bridges</strong></h3>
<p dir="ltr">Prevents support material from being generated under bridged areas.</p>
<h3 dir="ltr"><strong>Synchronize with object layers</strong></h3>
<p dir="ltr">Supports will be printed at equal layer heights as the model itself. This is useful with multi-material printers, where the extruder switch is expensive.</p>
<p>Synchronize with object layers can only be enabled with soluble supports (contact Z distance 0). </p>
<p>Not synchronizing with object layers allows the support layers to grow faster than the object layers (if not excessively slowed down by the cooling logic) and independent layer height also allows PrusaSlicer to follow the gap between the object and the support top surface precisely. We may consider this to be configurable even for non-soluble supports in the future.</p>

Flexible steel sheets (guidepost)

<p>The Magnetic heatbed enables you to use <strong>flexible</strong>, <strong>removable steel sheets</strong>. There are different properties and strengths of each sheet, but they also have different thickness which affects calibration.</p>
<div class="tip-callout">For more details on the different flexible steel sheet and their properties, please see <a href="http://help.prusa3d.com/article/flexible-steel-sheets-guidepost_2195">Flexible steel sheets (guidepost)</a>.</div>
<p>We implemented <strong>steel sheet profiles</strong> for our printers that need first-layer calibration. The function allows you to create up to eight specialized profiles for your printer setup. </p>
<p>For each sheet, set the Live Z adjust value. Once the values for each sheet are stored on the printer, it is possible to quickly toggle bewteen sheet profiles. The printer will not remind you to change the steel sheet profile, as it <strong>cannot sense which steel sheet is installed</strong>. </p>
<h3>How it works (MK2.5/S &amp; MK3/S/+)</h3>
<p>There are currently eight sheet profiles available with predefined, but customizable names.</p>
<p>To set up the individual sheet profiles, please head to the <em>LCD Menu</em> -&gt; <em>Settings -&gt; HW setup -&gt; Steel Sheets</em>:</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets-600x192.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets-800x256.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets-300x96.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets-768x246.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets.jpg 1600w" alt="hw setup profiles" width="600" height="192" loading="lazy" /></p>
<p>For each sheet, the following settings are available:</p>
<ul>
<li><strong>Select</strong> - confirms the selection of the sheet, which will then become the default</li>
<li><strong>First layer calibration</strong> - starts the <a href="http://help.prusa3d.com/article/first-layer-calibration-i3_112364">First Layer Calibration (i3)</a> process for the given profile</li>
<li><strong>Rename</strong> - enables you to change the name, by up to seven characters</li>
<li><strong>Reset</strong> - sets the values back to the factory defaults</li>
</ul>
<h4>Quick-toggle</h4>
<p>As soon as two or more profiles are configured (by the First Layer Calibration), you will be able to quick-toggle between them directly from the main menu.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets2.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets2-600x192.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets2-800x255.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets2-300x96.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets2-768x245.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/05/HW-setup-steel-sheets2.jpg 1600w" alt="hw profile 2" width="600" height="192" loading="lazy" /></p>
<div class="note-callout"><strong>Don't forget which profile you have attributed to which plate!</strong> Always carefully watch your first layer and in case the nozzle is too high or too low, stop the print and fix it either by setting the correct profile or by modifying the <a href="http://help.prusa3d.com/article/live-adjust-z_112427">Live adjust Z</a>.</div>
<h4>Renaming of the sheet</h4>
<p>After selecting the <strong>Rename</strong> option in the sheet profile menu, you can change up to 7 characters of the profile name. The word "Sheet" cannot be changed; it is the "<strong>Smooth1</strong>", "<strong>Textur1</strong>" etc. that you can customize. There is no way to delete or erase a wrongly selected character, but you can always restart the renaming procedure.</p>
<p>You start from the left and move to the right. By turning the knob, you are changing the characters, and by clicking it, you confirm the current character and move to the next one. When a character position is redefined, a small chevron mark will appear underneath it.</p>
<h3>How it works (MINI/+, MK3.5/S)</h3>
<p>To set up the individual sheet profiles, please head to the <em>LCD Menu -&gt; Settings -&gt; Hardware -&gt; Steel Sheets</em>.</p>
<p>For each sheet, the following settings are available:</p>
<ul>
<li><strong>Select</strong> - confirms the selection of the sheet, which will then become the default</li>
<li><strong>First layer calibration</strong> - starts the <a href="http://help.prusa3d.com/article/first-layer-calibration-mini-mini_229122">First Layer Calibration</a> process for the given profile</li>
<li><strong>Reset</strong> - sets the values back to the factory defaults</li>
<li><strong>Offset</strong> - sets the Live Z adjust value for the given profile, without calibration </li>

<p>The Satin sheet further expands our line-up of print sheets. In terms of printing properties, the Satin sheet sits between the <a href="http://help.prusa3d.com/article/smooth-steel-sheet_196550">smooth</a> and <a href="http://help.prusa3d.com/article/textured-steel-sheet_196534">textured</a> variants. Its fine powder-coated surface with a lightly textured matte finish offers an optimal level of adhesion, especially when printing PLA and PETG materials. It is fully compatible with a wide range of common and less-common filaments, such as ABS, ASA, FlexFill 98A, Polycarbonate (PC), and more.&nbsp;</p>
<h3>Main attributes</h3>
<ul>
<li>Suitable for both PLA and PETG</li>
<li>Lightly textured surface finish</li>
<li>Double-sided! Both sides can be used interchangeably.</li>
<li>Prints automatically detach after the sheet cools down</li>
<li>Wide range of supported filaments, including advanced materials (PC Blend, Polypropylene…)</li>
<li>Easy maintenance and good adhesion qualities</li>
</ul>
<h3>Considerations</h3>
<ul>
<li><strong>Never clean the sheet with acetone! It will deteriorate the surface.</strong></li>
<li>Keep the sheet clean! Any grease will greatly reduce adhesion.</li>
<li>Live Z value needs to be readjusted if you switch sheets. See <a href="http://help.prusa3d.com/article/steel-sheet-profiles_1955">Steel sheet profiles</a>.</li>
<li>Not scratch-resistant!!! Do not use metal spatulas etc. to remove the prints. We recommend printing a plastic spatula, like <a href="https://www.prusaprinters.org/prints/28337-scraper-for-build-plate-version-2">this one.</a></li>
<li>Small PLA prints may require a <a href="http://help.prusa3d.com/article/skirt-and-brim_133969#brim">Brim</a>.</li>
<li>Apply a glue stick when printing with TPU or TPEE.</li>
<li>Prints from ASA and PC Blend have a lower adhesion on satin compared to on the smooth sheet. Prints often require brim and/or shield (skirt <a href="http://help.prusa3d.com/article/skirt-and-brim_133969#skirt">"Draft shield" around the object</a> is a feature in PS 2.3)</li>
<li>PC blend works perfectly with the clean satin sheet, however, it might cause wear after some time. <strong>If you print PC often, a glue stick separation layer is recommended to prevent potential damage to the sheet.</strong></li>
</ul>
<div class="warning-callout">Consumable parts, such as print sheets (satin, smooth, textured, etc.) are not covered by warranty as the coatings will diminish over time. Unless failure has occurred due to a defect in materials or workmanship, cosmetic damage, including but not limited to scratches, dents, cracks, or other cosmetic damage is also not covered by the warranty. Only defective sheets on arrival are covered by warranty.</div>
<h3>Maintenance</h3>
<ul>
<li>Attracts fingerprints - A good indication of where your sheet is dirty/greasy and that you need to clean it. Clean with ~90% IPA when the sheet is cold. If ~90% IPA is not sufficient, clean with dishwasher soap. <strong>Do not leave the sheet wet!</strong> It has an anti-corrosion layer but is still not recommended.</li>
<li>Never clean with acetone! Same issue as with the textured sheet (surface deteriorates)</li>
<li>Some types of paper towels may leave traces on the sheet (fiber pieces).&nbsp;</li>
</ul>
<h3>Filaments</h3>
<p>We have done a lot of testing and compiled our results for you to use. To easily see how to prepare your sheet for any filament type, please <a href="https://help.prusa3d.com/en/materials">see our Material table</a>.</p>
<h3>Prints don’t stick</h3>
<p>If your print surface is perfectly clean and all grease has been removed by wiping it with a paper towel soaked in isopropyl alcohol ~90% and if the first layer height is set up perfectly, yet your print still does not adhere reliably to the print surface, check out <a href="http://help.prusa3d.com/article/first-layer-issues_1804">First layer issues</a>.</p>

<p>The powder-coated sheet, also referred to as the <em>textured sheet</em>, has its surface covered with a special polymer (Ultem PEI) to ensure perfect adhesion. These have been used in our print farm for many years and are perfect when printing a lot of <em>high-adhesion</em> filaments like PETG, and are also ideal for printing flexible filaments (TPU). It has a rougher texture than the <a href="http://help.prusa3d.com/article/satin-steel-sheet_196526">Satin sheet</a> and is more durable with some filaments than the <a href="http://help.prusa3d.com/article/smooth-steel-sheet_196550">smooth sheet</a> .</p>
<div class="note-callout">The exact color depicted in the e-shop and our knowledge base may differ from yours. All sheets are checked and verified being within tight specifications.

<p>If your prints still do not adhere reliably to the print surface, try to wash the sheet in warm water (not hot!) with a few drops of liquid dish soap (not hand soap). This should not be done often, and <strong>do not submerge the sheet completely in hot water</strong>, bu this can clean away oils/sugars that are not affected by rubbing alcohol.

Textured steel sheet

<p>Prusa printers are well known for being very silent, even in the standard mode. But actually, our printers also offer an option for even quieter operation. In the instructions below you will learn how to set your printer to <strong>stealth mode</strong>. </p>
<h3>MK4/S, MK3.9/S, MK3.5/S, XL, MINI/+</h3>
<p>Starting from firmware versions 6.0.0 and above, two print modes are offered on the Original MK4/S, MK3.9/S, MK3.5/S, XL, and MINI/+. This is set by toggling the <strong>Stealth Mode</strong>. In idle mode, navigate to <em>LCD menu -&gt; Settings</em>. </p>
<div class="tip-callout">It is also possible to switch between Normal and Stealth mode during a print. In this case, navigate to <em>LCD menu -&gt; Tune</em>. In this case, the selected mode will be activated once several G-code commands in the buffer (printer memory) are processed. </div>
<p>Once the stealth mode is enabled, the firmware sets a limit to acceleration, feedrate, and jerk values. Setting a cap on these parameters will lower the noise. The trade-off is an increased print time. </p>
<div style="text-align: center;"><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2024/04/0e4957cf8cdacd8329aba7f8e48da512.bmp" sizes="(min-width: 1024px) 820px, 100vw" srcset="Power modes (REVIEW)" alt="" width="450" height="300" loading="lazy" /><em>Screenshot from the Original Prusa MK4</em></div>
<p></p>
<h3>MK3 and MK3S/+</h3>
<h4>Normal vs. Stealth mode</h4>
<p>MK3 series printers offer two print modes. <strong>Normal mode</strong> is required for the detection of lost steps (shifted layers), while still being quieter than the silent mode on MK2/S. There is also the <strong>Stealth mode,</strong> which utilizes Trinamic StealthChop technology. This makes the printer almost inaudible where the print cooling fan is the noisiest part of the printer.</p>
<div class="warning-callout"><strong>Stealth mode</strong> does not provide Crash detection (lost steps cannot be detected).</div>
<p><strong>These modes can be switched depending on the situation:</strong></p>
<ol>
<li>When idle:
<p><em>LCD Menu -&gt; Settings -&gt; [Normal / Stealth mode]</em></p>
</li>
<li>During a print:
<p><em>LCD Menu -&gt; Tune -&gt; [Normal / Stealth mode]</em></p>
</li>
</ol>
<h3>MK2/S, MK2.5 and MK2.5S</h3>
<h4>Power vs. Silent mode</h4>
<p><strong>The silent mode</strong> uses less current and makes the printer quieter but less powerful. <strong>Hi-power mode</strong> is great for very large (over 200 gram) prints. It is also recommended for newly assembled kits before you fine-tune everything. If you experience lost steps (shifted layers) or if you’re manually adjusting the speed of printing to more than 100%, use <strong>Hi-power mode</strong>.</p>
<h4>Auto power mode</h4>
<p>There is also an <strong>Auto Power Mode</strong>. This is basically a compromise between silent and hi-power modes. The stepper currents depend on the Z height. The current starts low when the Z height is minimal. And it increases slowly as the object is printed. </p>
<p><strong>These modes can be changed in two ways:</strong></p>
<ol>
<li>When idle:
<p><em>LCD Menu -&gt; Settings -&gt; [Hi-power mode / Silent mode / Auto power mode]</em></p>
</li>
<li>During a print:
<p><em>LCD Menu -&gt; Tune -&gt; [Hi-power mode / Silent mode / Auto power mode]</em></p>
</li>
</ol>

<p>Both sides of the smooth sheet are covered by a sticker made from PEI plastic. This is the same time-tested surface type that was used on the older MK2S printers. This sheet provides excellent adhesion with most filaments and geometry. So much in fact, that some filaments, like TPU and PETG, will adhere too much and can damage the sheet when removed. That is why we also have available the <a href="http://help.prusa3d.com/article/textured-steel-sheet_196534">Textured sheet</a> and the <a href="http://help.prusa3d.com/article/satin-steel-sheet_196526">Satin sheet</a>.&nbsp;</p>
<h3>Main attributes</h3>
<ul>
<li>Ideal for printing PLA, HIPS, ABS/ASA, composite materials (metal/wood).</li>
<li>Prints with sharp corners or a small first-layer area are less likely to detach.</li>
<li>Scratch-resistant. Can be used with a metal spatula, however, cosmetic scratches may appear.</li>
<li>Double-sided! Both sides can be used interchangeably.</li>
<li>Compatible with most types of filament.</li>
<li>Thicker than the Textured and Satin sheet.</li>
<li>Little to no surface preparation, (other than cleaning).</li>
<li>Clean with ~90% Isopropyl alcohol (IPA) or denatured alcohol.</li>
<li>Can be cleaned with acetone, but do not overuse it (1-2 times per month).</li>
<li>ABS juice can be applied to the sheet.</li>
</ul>
<h3>Considerations</h3>
<ul>
<li>Live Z value needs to be readjusted if you switch sheet-type. See <a href="http://help.prusa3d.com/article/steel-sheet-profiles_1955">Steel sheet profiles</a>.</li>
<li>Some filaments, like PETG, ASA, ABS and PC Blend, may need a protective separation layer, like gluestick applied thinly before printing! See our extensive <a href="https://help.prusa3d.com/en/materials">Material table.</a>.</li>
<li>Keep the sheet clean! Any grease will greatly reduce adhesion.</li>
</ul>
<h3>Maintenance</h3>
<ul>
<li>Clean with ~90% IPA (isopropyl alcohol) or denatured alcohol when cold. Apply on unscented paper towel and rub the sheet down. <em>Do not use anything made for skin!</em> It can contain oils that ruin adhesion!</li>
<li>1-2 times a month it can be cleaned the same way with acetone if IPA cleaning is not sufficient.</li>
<li>After extended use (1-2 years) the surface can smooth out further, which affects adhesion. Using high-grit sandpaper (600-1000), the PEI can be revived by light sanding, bring fresh PEI to the surface. The sheet will have a very light texture after this treatment.</li>
<li>The smooth PEI film on the steel sheet <a href="http://help.prusa3d.com/guide/replacing-the-pei-sheet-on-the-mk3s-mk3-mk2-5s-mk2-5_23920">can be replaced in case of extensive damage</a>.</li>
</ul>
<h4>Bubbles underneath the PEI</h4>
<p>Over time, you might see some small bubbles underneath the PEI. This is nothing serious. These bubbles usually do not affect print quality and will disappear after a few days or weeks. Here are 2 tips that will make these bubbles disappear faster:</p>
<ol>
<li>Swap the side of the steel sheet you were printing on. This will speed up the "recovery" of the PEI surface.&nbsp;<br />
Bubbles appear around the spot where you print the most (center of the sheet), most often underneath the corners of your printed parts.</li>
<li>When slicing the models, vary your placement on the print surface. Don't use just one spot i.e. the center.</li>
</ol>
<h4>Dent in the PEI</h4>
<p>Sometimes, there might be a small dimple or dent in the smooth PEI layer when you first unpack the steel sheet. Don't worry, just flip the sheet over and use the other side. Thanks to the heat of the heatbed, the dent will disappear by itself after some time (about 1-2 days of print time).</p>

Smooth Steel Sheet

<p>Due to some inconsistencies in readings from the <a href="http://help.prusa3d.com/article/filament-sensor-mk3-non-s_2125">optical filament sensor</a> we created the <strong><em>MK3 to MK3S</em></strong> upgrade to address this. The new IR filament sensor still uses an optical sensor but is triggered by a mechanical action designed into the new plastic parts of the MK3S, and MK2.5S extruder. </p>
<p>Other printer models equipped with the IR filament sensor are the MK3S+, and the MK3.5/S. </p>
<p><img decoding="async" style="max-height: 450px; display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/IR-sensor.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/IR-sensor-300x225.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/IR-sensor-533x400.png 533w, https://cdn.help.prusa3d.com/wp-content/uploads/IR-sensor-768x576.png 768w" data-hd-height="450px" data-hd-align="center" /></p>
<div class="note-callout">The new filament sensor does not detect clogging but is much more robust and reliable for Autoload and run-out detection.</div>
<h3>Autoload</h3>
<p>Autoload is a function that, if the hotend is heated, will start the loading procedure once filament is detected. This can be turned ON and OFF from <em>Settings -&gt; Autoload</em>, on the LCD-panel. The filament sensor must be turned on, from the same menu, to be able to utilize the Autoload feature.</p>
<div class="tip-callout">If you are doing a cold pull or troubleshooting the extruder and hotend it may be wise to disable Autoload.</div>
<h3>Running out of filament</h3>
<p>If you run out of filament, the printer will automatically pause the print, move the X-carriage away from the print and prompt you to unload the remaining few centimeters of the material from the heatbreak and replace the spool and insert a new filament.</p>
<h4>The printer will guide you on how to resume printing safely: </h4>
<ol>
<li><em>"Please press the knob to unload the filament"</em> = Press the knob to unload the remaining few centimeters of the filament.</li>
<li><em>"Repeat unloading filament?</em>  <strong>[Yes/No]</strong> = If everything went well, press <strong>[Yes]</strong>. If not, then press <strong>[No]</strong>. The printer will lock the x-axis motor and will allow you to open the extruder idler to clear the remains of the filament manually.
<ol>
<li>To open the extruder idler, simply release the spring screw running through the extruder, holding the idler-door.</li>
<li>Then, you can use the bundled pliers to remove the filament remains. If some of it got stuck in the top PTFE tube, simply push it out with new filament. </li>
<li>Close the extruder idler by re-tightening spring tensioned screw. The Head of the screw should be about flush with the plastic parts when the filament is loaded.</li>

<h3>Nozzle diameter setup</h3>
<p style="box-sizing: inherit; margin-top: 0px; margin-bottom: 1rem; color: #373a3c; font-family: Lato, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 16px; background-color: #fefeff;">By default, all Original Prusa printers are shipped with the 0.4 mm nozzle. In case you change the nozzle, you can set the correct diameter. The printer will then compare the stored value of the nozzle diameter with parameters saved by our Prusa Slicer in the G-code. If there is a mismatch, the printer is able to inform you and thus prevent a print failure.</p>
<div class="tip-callout">This setting does not affect extrusion rates (flow) during First Layer Calibration. The article <a href="http://help.prusa3d.com/article/different-nozzle-types_2193">Different nozzle types</a> will tell you more about First layer calibration for different nozzles.</div>
<h3>Preliminary checks</h3>
<p style="box-sizing: inherit; margin-top: 0px; margin-bottom: 1rem; color: #373a3c; font-family: Lato, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 16px; background-color: #fefeff;">Besides checking the nozzle diameter, the printer is now able to check other parameters to warn you about incompatible settings. Before a print starts, the printer will compare parameters stored in the memory with the G-code.</p>
<p>The controller parameters are as follows:</p>
<ul>
<li><strong>Nozzle</strong> diameter (0.25, 0.4, 0.6 etc.)</li>
<li><strong>Model</strong> if the printer g-code is sliced for (MK3, MK3S+, MK2)</li>
<li><strong>Firmware</strong> version</li>
</ul>
<p style="box-sizing: inherit; margin-top: 0px; margin-bottom: 1rem; color: #373a3c; font-family: Lato, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 16px; background-color: #fefeff;">For each you can set three levels of warnings for each controlled parameter:</p>
<ul style="box-sizing: inherit; margin-top: 0px; margin-bottom: 1rem; color: #373a3c; font-family: Lato, 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 16px; background-color: #fefeff;">
<li style="box-sizing: inherit;"><strong>[none]&nbsp;</strong><em style="box-sizing: inherit;">-</em>&nbsp;checking is turned off, the user won't receive any notification</li>
<li style="box-sizing: inherit;"><strong>[warn]</strong> - a warning message will be displayed on the screen, then the user can continue with the print</li>
<li style="box-sizing: inherit;"><strong>[strict]</strong> - a warning message will be displayed on the screen, the user&nbsp;<em style="box-sizing: inherit;">can't</em> continue until he fixes the issue, and print is aborted.</li>
</ul>

<p>The printer tracks printing statistics. When you access this option during a print, you will see statistics for the running print. If you do so while the printer is idle, you will see the total statistics. Both filament usage and print time are tracked.</p>
<p>You can find this menu in the LCD Menu -&gt; Statistics. The data can be easily reset once you do a <a href="http://help.prusa3d.com/article/factory-reset-mk2s-mk2-5s-mk3s_2216">Factory reset (MK2S/MK2.5S/MK3S)</a>.</p>

</table>
<p>The special PA Nylon sheet is made for printing polyamides (Nylon) since their adhesion to standard PEI sheets is generally very poor. The sheet comes with a matt texture, similar to the <a href="http://help.prusa3d.com/article/satin-steel-sheet_196526">satin</a> steel sheet with a PEI surface. The sheet is compatible with most polyamides and PETG, other materials may have insufficient adhesion and should be printed on our standard PEI sheets.</p>
<h3>Main attributes</h3>
<ul>
<li>Compatible with many types of polyamide</li>
<li>Made for printing without using a glue stick and other means of increasing adhesion</li>
<li>Slightly textured surface</li>
<li>Double-sided! Both sides can be used repeatedly</li>
<li>Easy maintenance and good adhesion qualities</li>
</ul>
<h3>Considerations</h3>
<ul>
<li><strong>Never clean the special PA Nylon sheet with acetone, IPA (isopropyl alcohol), or other alcohol-based solvents (window cleaners, Windex, etc.)! This will damage the surface.</strong></li>
<li>For easy print removal, wash the print surface with water before every printing.</li>
<li>Check the proper first layer height! If the Live Z value is too low and the first layer is too squeezed, print removal may be difficult and may damage the sheet.</li>
<li>PA Nylon sheet should be cleaned only with water and degreased with dish-washing soap!</li>
<li>Some types of polyamide may be prone to warping and require using brim or are suitable only for printing small parts and models with sparse infill.</li>
<li>Keep the sheet as clean as possible! Any grease stain will decrease adhesion.</li>
<li>Live Z value needs to be readjusted if you switch sheets. See <a href="http://help.prusa3d.com/article/steel-sheet-profiles_1955">Steel sheet profiles</a>.</li>
<li>Not scratch-resistant!!! Do not use metal spatulas with sharp edges to remove the prints. Be extremely careful when removing the print.</li>
<li>Small PETG prints may require a <a href="http://help.prusa3d.com/article/skirt-and-brim_133969#brim">Brim</a>.</li>
</ul>
<div class="warning-callout">Consumable parts, such as print sheets (satin, smooth, textured, etc.) are not covered by warranty as the coatings will diminish over time. Unless failure has occurred due to a defect in materials or workmanship, cosmetic damage, including but not limited to scratches, dents, cracks, or other cosmetic damage is also not covered by the warranty. Only defective sheets on arrival are covered by warranty.</div>
<h3>Maintenance</h3>
<ul>
<li>Wash the print surface before every print with clean water (use a wet cloth or sponge…), then dry it. Greasy stains, such as fingerprints, can be cleaned with water with dishwashing soap.</li>
<li>Never use anything to clean PA Nylon steel sheet but water (with a drop of dish-washing soap)! Unlike the PEI sheets, the PA Nylon sheet must not come in contact with alcohol-based solvents (IPA, Ethyl alcohol, etc.), Acetone, window cleaners, 3DLAC, etc. Using any unrecommended solvents leads to a shorter sheet lifespan and risk of damaging the surface!</li>
<li>Some types of paper towels may leave traces on the sheet (fiber pieces). </li>
</ul>
<h3>Filaments</h3>
<p>We have done a lot of testing and compiled our results for you to use. To easily see how to prepare your sheet for any filament type, please <a href="https://help.prusa3d.com/en/materials">see our Material table</a>.</p>
<h3>Prints don’t stick</h3>
<p>If your print surface is perfectly clean and all grease has been removed by wiping it with a paper towel soaked in water and dish-washing soap, the first layer height is set properly and the print won’t stick, check out <a href="http://help.prusa3d.com/article/first-layer-issues_1804">First layer issues</a>.</p>
<p>Keep in mind that polyamides in general tend to warp more than other materials. Sometimes warping may be so strong that larger models (or with dense infill) detach from the surface even over the best surface adhesion. If you experience such strong warping, we recommend using another type of PA for selected print - for example, our Prusament PA11 Carbon Fiber shows almost no warping at all. You can find more in the articles about polyamide and warping.</p>
<div class="warning-callout">PA Nylon print sheet has a special surface layer with smooth texture and matt looks. The surface layer is partially translucent and may show a specific “texture” of lengthwise or diagonal lines, or varying color shades. These color variations are characteristic for material under the topmost layer and don’t affect sheet performance.</div>
<h3>Notes</h3>
<p><em>As a result of the temperatures to which the plate is exposed during printing, its surface gradually becomes glossier or may develop smaller, duller areas. </em><em>This visual change does not adversely affect the printing properties and is not considered a reason for a warranty claim.</em></p>
<p><em>Note that with the Original Prusa MK4 and XL, the PA Nylon sheet wear is especially noticeable at the Z probing points, where the nozzle leaves visible marks on the surface. This does not affect the surface adhesion and overall printability.</em></p>
<p><em>A new batch of the PA Nylon sheet will be released during July / August 2024. The new version will get a slightly rougher surface texture. This change will not affect the print sheet's functional properties. You can examine the changes in the gallery below.</em></p>

Special PA Nylon steel sheet

<p>Starting accidentally another action during the print (e.g. XYZ calibration, switching sheet profiles, ...) can cause damage to the printer. This is why during the entire printing phase most of the menu items are unavailable. The safety of the user and the printer is the biggest priority.&nbsp;</p>
<p>However, some parameters can be adjusted (e.g. temperatures, flow, sound mode, ...) and those are shown in a special list called "Tune menu". The list differs from printer to printer and is expanded based on the new features and customer feedback.</p>
<p><strong>Example of the "Tune menu" on the MK3S:</strong></p>

<div class="warning-callout">The Crash dump is not used for troubleshooting normal printer errors! Please only supply the Crash dump if requested.</div>
<p>If there is a software crash on the printer, a Crash dump will automatically be saved in the xFlash memory. When troubleshooting the cause of the crash, our <a href="http://help.prusa3d.com/article/customer-support_2287">Customer support</a> may request this Crash dump. This feature can be used for diagnosing unusual system issues.</p>
<p>The Crash dump has important information about your printers, like the serial number and IP address. Sharing this data publicly is not recommended.</p>
<p>In Windows, it is possible to correctly recover the dump with either <a href="http://help.prusa3d.com/article/crash-dump_364959#putty">PuTTY</a> or <a href="http://help.prusa3d.com/article/crash-dump_364959#octoprint">OctoPrint</a>.</p>
<p>The Crash dump to xFlash is active at any time, it is stored in xFlash and can be downloaded even after the system reboot until a D22 command (clear the current memory dump in the printer) is sent to the printer.</p>
<div class="note-callout">Using programs other than the recommended ones for the serial link might cause the dump to be unusable.</div>
<h3>MK2.5, MK2.5S</h3>
<p>The MK2.5 and MK2.5S do not contain the xFlash, so the crash dump will not be saved automatically after a crash. Therefore, the crash dump can only be retrieved if the printer is already connected to a serial link at the time of the crash.</p>
<h3>PuTTY</h3>
<p>Download the program <a href="https://www.putty.org/">here</a>. Once downloaded, start the program, then:</p>
<ol>
<li>On the "Connection type" select "Serial".</li>
<li>On the field "Serial line", type the COM port that the printer is connected to (the picture is an example, check your device manager to know the COM port used in your computer).</li>
<li>Set the speed to 115200.</li>

<h3>OctoPrint</h3>
<p>In order to get the Crash dump using Octoprint, it is necessary to enable "Serial logging" in the <em>OctoPrint Settings -&gt; Printer -&gt; Serial Connection</em> <em>-&gt; General</em> section. Scroll all the way down, check the box under "Serial logging", and click the Save button.</p>
<p>To get the dump, use the serial command D21 (read crash dump).</p>
<p>You can either download the OctoPrint serial log by going to <em>Settings -&gt; Octoprint -&gt; Logging</em> and clicking on the download icon at the right of "serial.log". Or you can copy the dump from "D21" until "ok", and paste it into a text editor like Notepad++. Compress/zip the file before sending it.</p>
<p>If you don't use serial logging by default, disable it after the dump again.</p>

<p>In case you experiencing issues with the screen readability, you can try adjusting the contrast on the LCD-module. On the back of the LCD-module, you will find a small potentiometer dedicated to this. <strong>If adjusted to an extreme, the image of the LCD-module can be entirely burned out, with no visible letters.&nbsp;</strong></p>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/LCD-contrast-scale2.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/LCD-contrast-scale2-600x208.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/LCD-contrast-scale2-800x278.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/LCD-contrast-scale2-300x104.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/LCD-contrast-scale2-768x267.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/LCD-contrast-scale2-1536x533.jpg 1536w" alt="" width="800" height="278"></p>
<p style="text-align: center;"><em>LCD module adjusted to 4 different levels</em></p>
<h3>How to adjust the contrast</h3>
<p>Before you dive into the disassembly, ensure once again that the cables are properly connected both to the LCD and to the Einsy board. Some image distortions can be caused just by incorrectly seated connectors.&nbsp;</p>
<div>
<div class="warning-callout">Be careful, don't use objects with sharp tips, and don't press too hard. You might damage the board!</div>
<div>It may be possible to access the adjustment potentiometer without any disassembly, from below the LCD. However, it may be difficult to adjust when still mounted to the printer. <em>Your LCD module may be a different color than what is depicted, but the procedure remains the same.</em></div>
<div>&nbsp;</div>
</div>
<ol>
<li>Detach the LCD assembly by removing the 4 screws that hold the LCD module (<span style="color: #b96ad9;">purple arrows</span>). <em>By sliding the printer to the edge of the table you will have access to the screws from below.</em></li>
<li>Remove the two screws securing the module in the cover (<span style="color: #236fa1;">blue arrows</span>).</li>
<li>Remove the LCD module from the cover and slide off the LCD-holder (<span style="color: #2dc26b;">green arrows</span>)</li>

<div class="warning-callout">The memory dump is not used for troubleshooting normal printer errors! Please only supply the Memory dump if requested.</div>
</div>
<p>Starting from firmware version 3.10.1, the Original Prusa MK3/S/+ and MK2.5/S have the option of Dump Memory, which will store the RAM content in the xFlash memory. This can be used for diagnosing unusual system issues.</p>
<p>The Memory dump has important information about your printers, like the serial number and IP address. Sharing this data publicly is not recommended.</p>
<h3>MK3, MK3S, and MK3S+</h3>
<p>To access the feature, go to <em>LCD menu -&gt; Support -&gt; Dump memory</em>. This can be used at any time, even during printing.</p>
<p>Note that the printer will stop for the snapshot and it will take some time to finish, therefore we advise you not to use this feature if you are not experiencing any problems.</p>
<p><img decoding="async" loading="lazy" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/Memory-dump.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/Memory-dump-600x192.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/Memory-dump-300x96.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2022/09/Memory-dump.jpg 1600w" alt="" width="500" height="160"></p>
<p>The only way to correctly get the saved dump from the printer is by connecting the printer using PuTTY or OctoPrint in the same way as the <a href="http://help.prusa3d.com/article/crash-dump_364959">Crash dump</a>.</p>
<div class="warning-callout">Please be aware not to connect the serial link during print as it can restart the printer and break the recent printing job.</div>
<p>The Dump memory to xFlash is active at any time, it is stored in xFlash and can be downloaded even after the system reboot. It will be deleted when a new <code class="codesample-inline">D22</code> command is sent to the printer.</p>
<h3>MK2.5, MK2.5S</h3>
<p>Since the MK2.5 series does not contain the xFlash, the dump memory cannot be stored, so it needs to be sent to a serial link connection. In order to get the memory dump from the printer, there must be a serial link connection available prior to any dump download. In default, the <em>LCD Menu -&gt; Support -&gt; Dump to serial</em> and crash dump are disabled after the printer restart.</p>
<p>To get the dump the following process has to be followed and serial commands used:</p>
<ol>
<li>Connect the serial link to Printer. As the serial link connection restarts the Printer, it has to be done before any further activity.</li>
<li>Using the <code class="codesample-inline">D23</code> command from the serial link enables the crash dump by setting the crash dump flag and activates the <em>LCD Menu -&gt; Support-&gt; Dump to serial</em> display menu.</li>
<li><code class="codesample-inline">D23 R</code> command disables the crash dump and removes the <em>LCD Menu -&gt; Support-&gt; Dump to serial</em> display menu.</li>
<li>The command D23 E - sends the Dump down to the serial link immediately and resets the printer.</li>
<li>Command <code class="codesample-inline">D20</code>, <code class="codesample-inline">D21</code>, <code class="codesample-inline">D22</code> are ignored.</li>
<li>The Dump to serial command should be available even during print and should be found again under LCD Menu -&gt; Support-&gt; Dump to serial display menu.</li>
</ol>
<p>In case any strange characters appear on the screen, press the reset button below the LCD knob.</p>
