<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>
<p dir="ltr"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/support_overhang_threshold.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/support_overhang_threshold-300x171.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/support_overhang_threshold-600x342.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/support_overhang_threshold-768x437.png 768w, https://cdn.help.prusa3d.com/wp-content/uploads/support_overhang_threshold-800x455.png 800w" alt="" /></p>

<h3 dir="ltr"><strong>Enforce support for the first</strong></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>

<p>Updating the firmware is <strong>recommended for all users</strong> as every new version brings new features and fixes.</p>
<div class="tip-callout"><strong>To utilize the new SuperPINDA, your MK3S must at least have firmware version 3.9.2!</strong></div>
<p>To flash the firmware onto your printer, you need:</p>
<ul>
<li>Computer running Windows, macOS, or Linux</li>
<li>USB cable, preferably the original included with your printer</li>
<li>PrusaSlicer and the printer's driver installed (download <a href="https://www.prusa3d.com/drivers/" target="_blank" rel="noopener noreferrer">here</a>)</li>
</ul>
<p>To check which firmware version you already have on your printer, power it up and go to <em>LCD menu -&gt; Support</em>. Scroll down and you will see the firmware version<strong>. The procedure for installing an older version of the firmware (downgrading) is exactly the same.</strong></p>

Prusa Connect &amp; PrusaLink

<p>Prusa Connect and PrusaLink are two remote printing solutions developed in-house by Prusa. Its origin is in the management system used in our <a href="https://blog.prusaprinters.org/guinness-world-records-1096-original-prusa-3d-printers-running-at-the-same-time_30677/">record-sized print farm located in Prague HQ.</a></p>
<ul>
<ul>
<li><strong>Prusa Connect</strong> is a cloud service for remote printing available from anywhere.</li>
<li><strong>PrusaLink</strong>* is the client-side running locally on your printer, accessible from local network</li>
</ul>
</ul>
<p><em>*formerly known as Prusa Connect Local</em></p>
<p> </p>
<h2>What is Prusa Connect?</h2>
<p>Prusa Connect (<a href="http://connect.prusa3d.com">connect.prusa3d.com</a>) allows you to control your individual printers or even manage a print farm from anywhere in the world.</p>
<p style="text-align: center;"><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/08/9f18d1552ef82ea7ef4960a43a86a17b.png" sizes="(min-width: 1024px) 820px, 100vw" srcset="Prusa Connect and PrusaLink explained" alt="" width="900" height="607" loading="lazy" /></p>
<p style="text-align: center;"><em>Example of Prusa Connect interface (cloud service)</em></p>
<p> </p>
<p>It is available for free to the owners of selected Original Prusa printers (see the list below). You get a free 1 GB of cloud storage for your G-codes and telemetric data. The full list of features and pricing for end customers or businesses will be announced later on.</p>
<p>Furthermore, Prusa Connect is able to monitor the use of each printer individually, providing valuable statistics of your production environment. </p>
<p> </p>
<h2>What is PrusaLink?</h2>
<p>Much like <a href="http://help.prusa3d.com/article/about-octoprint_1790">Octoprint</a>, this remote printer-management system runs locally on your Original Prusa printer.</p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/01/12af6bd49830e088.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="PrusaLink and Prusa Connect explained" alt="" width="1451" height="800" loading="lazy" /></p>
<p style="text-align: center;"><em>Example of PrusaLink interface (local network)</em></p>
<p> </p>
<p>Its main goal is to provide communication between your printer and the Prusa Connect cloud. The secondary function is to provide a web interface, which can be used on your local (home) network only. Simply paste the printer's IP address into your web browser to access it. Using PrusaLink alone you can monitor your printer, upload G-codes, start or cancel a print. </p>
<p> </p>
<h2>How to install and configure PrusaLink and Prusa Connect?</h2>
<p>To use the Prusa Connect, you have to first set up the PrusaLink on your printer. The guides below will take you to step by step through the entire process.</p>

<h3>Original Prusa i3 MK3/S/+ or MK2.5/S</h3>
<p>In this case, the PrusaLink name also refers to the required hardware solution of a Raspberry Pi (RPi). These printers don't have enough performance, therefore additional hardware is required. PrusaLink is a replacement for the discontinued <a href="http://help.prusa3d.com/article/prusaprint-rpi-zero-and-octoprint_2180">PrusaPrint solution</a> (Octoprint and the RPi Zero W).</p>
<h4>Which Raspberry Pi should I get for my i3 (MK3/S/+ or MK2.5/S)?</h4>
<p>For your MK3/S/+, you need to get a Raspberry Pi (RPi) to make the PrusaLink and Prusa Connect work. The supported RPi boards are listed below and if you are about to purchase a new one, it is highly recommended to seek the latest generation, as the older ones might be slower.</p>
<p>On MK3/S/+, you can attach the RPi Zero <a href="http://help.prusa3d.com/guide/prusalink-and-prusa-connect-setup-mk3-s-_221744">directly onto the printer’s mainboard</a> or use the <a href="http://help.prusa3d.com/guide/prusalink-prusa-connect-with-rpi-3-4-usb-mk2-5-s-mk3-s-_469341">USB connection</a>.<br />On MK2.5/S, you have to use the <a href="http://help.prusa3d.com/guide/prusalink-prusa-connect-with-rpi-3-4-usb-mk2-5-s-mk3-s-_469341">USB connection</a> to the RPi. Then, the PrusaLink and PrusaConnect setup is fairly similar to the MK3/S/+.</p>
<p>Since the RPi doesn't have internal storage, you need to get a MicroSD card. Recommended SD card: Micro SD, SDHC standard, Class 10, 8GB or more. Preferably, choose a name-brand card known to work with RPi. Do backups regularly as even a name-brand card doesn’t guarantee you won’t lose your data. </p>

Prusa Connect and PrusaLink explained

<p>PrusaSlicer separates the printer connection settings from the Printer profile into a <strong>Physical printer</strong> profile.</p>
<p>You can create a new Physical profile by clicking <em><strong>Add printer</strong></em> in the printer profile select box or by clicking the cog icon and picking <strong><em>Add physical printer</em></strong>.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-600x181.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-800x241.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-300x90.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-768x231.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-1536x463.jpg 1536w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-2048x617.jpg 2048w" alt="" width="503" height="152" loading="lazy" /></p>
<p>In the Physical printer dialog, you can name the printer and assign it one <strong>or more</strong> printer profiles. If you're using, for example, the MMU2S upgrade, you only have to set one physical printer, but you can have both Single mode and MMU profiles linked to it.</p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-printer.png" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-printer-600x337.png 600w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-printer-800x449.png 800w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-printer-300x168.png 300w, https://cdn.help.prusa3d.com/wp-content/uploads/2021/01/physical-printer-768x431.png 768w" alt="" width="561" height="315" loading="lazy" /></p>
<p>If you have a Physical printer with network info filled out selected as your current printer, you can send generated G-codes directly to your device.</p>
<h3>PrusaConnect</h3>
<p>If you'd like to send files to your printer via PrusaConnect, add a Physical printer or Edit an existing one.</p>
<p>Select <em><strong>PrusaConnect</strong></em> from the select box as the <em><strong>Host</strong></em><strong> type</strong><em>.</em> The hostname/IP will be automatically filled, you don't have to change it.</p>
<p><img decoding="async" loading="lazy" src="https://cdn.help.prusa3d.com/wp-content/uploads/2023/04/a6e53887e520db647ad830515ac5fb8a.png" sizes="(min-width: 1024px) 820px, 100vw" srcset="Sending G-codes to printer via network (PrusaConnect, PrusaLink, Octoprint)" alt="" width="1121" height="711" /></p>
<p>To find your API key, go to PrusaConnect, select the printer you want to send the files to, go to the <em><strong>Settings </strong></em>tab and scroll down to he <em><strong>API keys </strong></em>section. Copy <em><strong>PrusaConnect API key</strong></em> to the Physical printer window and confirm with OK.</p>

Sending G-codes to printer via network (PrusaConnect, PrusaLink, Octoprint)

<p>PrusaLink for Original Prusa <strong>MK2.5/S or MK3/S/+</strong> printers is powered by an Raspberry Pi (RPi) board. A camera can be connected to it either using CSI or USB connection.</p>
<p>Alternatively, the same camera setup is also compatible with <a href="http://help.prusa3d.com/guide/octoprint-setup-on-mk4-s-mk3-9-s-mk3-5-s-xl_646395">RPi + Octoprint</a> on <strong>MK4 / MK3.9 / XL</strong> printers. Note that PrusaLink itself running on <strong>MK3.9, MK4 </strong>and<strong> XL</strong> printers doesn’t support any cameras. You can use <strong>Prusa Connect</strong>, where it is possible to assign a camera to any of the supported Original Prusa printers.</p>

<h3>Compatible RPi cameras connected via CSI (MIPI):</h3>
<p>All the official RPi cameras in the list below have been tested and are compatible. PrusaLink uses a "<a href="https://github.com/prusa3d/Prusa-Link/blob/master/prusa/link/cameras/picamera_driver.py#L48">whitelist</a>" for CSI cameras. For example, if you connect RPi camera 3, it identifies to the RPi as "imx708" (according to the actual camera sensor it uses). The Wide-angle variant of the same camera identifies as  "imx708_wide". If you use a camera that would identify differently than any of the whitelisted ones, it won’t show up in PrusaLink.</p>
<p>There are also other compatible cameras than the ones listed below, such as some Arducam models. However, we haven’t tested them and can’t guarantee they will work as expected or will not cause any issues.</p>
<p>If your CSI camera doesn’t seem to work - and you are an experienced user, you can <a href="http://help.prusa3d.com/article/how-to-connect-to-rpi-via-ssh_658030">connect to PrusaLink using SSH</a>, or connect a keyboard + monitor to the RPi and use the following command to find out if the camera is detected and what it identifies as: <code class="codesample-inline">libcamera-hello --list-cameras </code></p>
<p>Note that due to limited computing capabilities of the Raspberry Pi Zero, the resolution might be limited to 1920px in both axes on this RPi model.</p>
<div>
<div class="warning-callout">Do not connect the cameras while the PrusaLink is running. Turn off the printer or disconnect the power before you connect the camera.</div>

Prusa Mobile App

PrusaLink and Prusa Connect setup (MK3/S/+)

<div class="warning-callout">This article is intended for experienced users only! During the regular RPi + PrusaLink operation, there should be no need to set up and use SSH.</div>
<div class="note-callout">Since we develop neither Raspberry Pi nor SSH functionality, we are only able to provide limited support on its use. </div>
<div>
<div class="tip-callout">For general info about the Prusa printer remote control services, visit the <a href="http://help.prusa3d.com/article/prusa-connect-and-prusalink-explained_302608">PrusaLink and Prusa Connect explained</a> article.</div>
</div>
<h3>What is SSH?</h3>
<p>SSH is a way to remotely send command line commands to the Raspberry Pi over a secure connection. This enables the user to control their RPi without having it hooked up to a monitor and a keyboard. This article describes a process on an RPi board with PrusaLink installed. </p>
<p>To connect to the RPi board remotely, you will need a computer with a working SSH client, like <a href="https://www.putty.org/">PuTTY</a> but most operating systems usually have SSH already integrated into their terminal.</p>
<h3>How to enable SSH on the RPi with PrusaLink?</h3>
<p>SSH can be enabled while setting up an SD card with PrusaLink image as described in the <a href="http://help.prusa3d.com/guide/prusalink-and-prusa-connect-setup-mk3-s-_221744#222334">Prusalink for MK3/S/+ guide</a>. You have to also set a device username + password. Note these credentials are different than your PrusaLink credentials or the Prusa Account.</p>
<p>To enable SSH on RPi with PrusaLink already installed and running, you have to connect the microSD card into a PC or a MAC and put a file named "ssh" without a file extension into the boot partition of the SD card. (A typical raspi SD has two partitions, "boot" and "root", although only the "boot" is accessible from Windows and Mac operating systems. To access the "root" partition, you have to use Linux or another similar Unix-based operating system.<br />Once the file is on there, safely remove the SD, put it back into the RPi and boot it up. You can now connect to your RPi by typing "ssh jo@&lt;IP_ADDRESS&gt;" into the commandline (replace "&lt;IP_ADDRESS&gt;" for the RPi's ip address). The default password is "raspberry", same as on every RPi. Only the username has been changed from "pi" to "jo" on PrusaLink.</p>
