<p>Introduced in version 4.3.0 for the MINI and MINI+, there is a section in the Settings-menu, called “HW setup”. It allows you to inform the printer/firmware of hardware changes and which actions to take in case of a conflict.&nbsp;</p>
<p>For the MINI there is currently only 1 option, "Steel sheet profiles". To access this, please go to the <em>LCD Menu -&gt; Settings -&gt; HW setup</em>. Please see <a href="http://help.prusa3d.com/article/steel-sheet-profiles_1955">Steel sheet profiles</a> for more details on taking advantage of this feature.</p>
<div class="tip-callout">More options will be added with future firmware updates.</div>

<p>The components installed on your printer rely on firmware configuration. To facilitate for components sourced from third-party vendors <strong>firmware version 4.3.3 introduced an "Experimental menu"</strong>. Because different hardware has different specifications, the firmware is now capable of adjusting the defining parameters of some components.</p>
<div class="warning-callout"><strong>The experimental menu is for advanced users.</strong> For a printer with stock parts, you should not make any changes to these firmware parameters! It can cause bad performance or even damage the printer and its parts.</div>
<p>To activate the experimental menu, navigate to <em>LCD menu -&gt; Settings</em> and scroll down to <em>HW Setup</em> <strong>without selecting it with a short-press</strong> (left picture). Instead, <strong>Hold the knob for 2-3 seconds</strong> and after a “click” sound, the Experimental menu will appear (right picture).</p>

<p>The Original Prusa magnetic heatbed is designed to hold a removable double-sided flexible spring-steel sheet, designed specifically for easy removal of printed objects from the print surface.</p>
<p><strong>We offer 3 different types of sheets</strong>, with different strengths and attributes. The first sheet released was with a <strong>Smooth PEI sticker on both sides</strong>. Second, after using it for several years in our own print farm, we solved reliable manufacturing of the <strong>powder-coated textured sheet</strong>, aimed at production environments using PETG and other high-adhesion filaments. The latest addition is <strong>the Satin sheet</strong>, which in both texture and properties lies between the smooth and the textured sheet. For more information on each sheet, please see their respective articles linked below.</p>

<h3><strong>General information</strong></h3>
<p>The removable spring steel sheet is held in place by a number of magnets glued to the heatbed, from the bottom side. On the top of the heatbed, there are two pins (left picture) that align perfectly with a notch in the spring steel sheet (right picture). <em>Before putting the steel sheet on the heatbed, make sure the heatbed is clean and free of any filament debris.</em></p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/prusuki/prusuki-images/aligning-pins.jpg"></p>
<div>
<div class="note-callout">Please ignore the two holes in the steel sheet that are on the opposite side of the notch. Those are from the manufacturing process and not for aligning the sheet on the bed.</div>
</div>
<h3>Steel sheet profiles</h3>
<p>Each sheet needs a different Live-Z value, as they have slightly different thicknesses. If you are using multiple different sheets, the value for each sheet can be stored in the Steel sheet profiles. For more information see the article <a href="http://help.prusa3d.com/article/steel-sheet-profiles_1955">Steel sheet profiles</a>.</p>
<h3>Removing prints</h3>
<p>To remove the printed object from the print surface, always wait until the steel sheet<strong>&nbsp;cools down to room temperature.</strong> Then you can take it off by <strong>bending the sheet</strong> inwards and outwards, but you may have to assist using a spatula to avoid damage to the sheet. <strong>For materials like PETG, ASA, ABS and PC Blend, and/or prints with a large first layer surface, a separation layer in the form of gluestick may be required.</strong></p>

<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>Differences between the sheets</h3>
<p>It is possible to use all sheets for printing almost any type of material if cleaned properly and the first layer (Live Z) set correctly. However, there are certain benefits to using one sheet or the other for certain materials and models.</p>
<div class="warning-callout">The smooth and textured sheets have a different thickness, which requires you to redo the <a href="http://help.prusa3d.com/article/first-layer-calibration-i3_112364">First Layer Calibration (i3)</a> or make use of different <a href="http://help.prusa3d.com/article/steel-sheet-profiles_1955">Steel sheet profiles</a>, when switching between them.</div>

<h4>Smooth PEI sheet</h4>
<p>Both sides of this sheet are covered by a sticker made from smoothed PEI plastic. This is the same time-tested surface type that was used on the older MK2S printers. Prints with a small area touching the print-surface or with sharp corners are less likely to detach when printing on the smooth spring steel sheet. Some users also like the smooth and shiny bottom side of their prints. <strong>For all details and considerations of the Smooth sheet, please see <a href="http://help.prusa3d.com/article/smooth-steel-sheet_196550">Smooth Steel Sheet</a>.</strong></p>
<h4>Powder-coated textured sheet</h4>
<p>The surface of this sheet is covered with a special polymer (Ultem) to ensure perfect adhesion. The powder-coated steel sheets are better for printing objects with materials such as PETG, CPE, or Flexfill (TPU) which tend to adhere too much to a smooth surface, but can be more easily removed from the textured one. <strong>For all details and considerations of the Textured sheet, please see <a href="http://help.prusa3d.com/article/textured-steel-sheet_196534">Textured steel sheet</a>.</strong></p>
<h4>Satin sheet</h4>
<p>The Satin sheet further expands our line-up of print sheets. Its powder-coated surface with a lightly textured matte finish offers an optimal level of adhesion and is fully compatible with a wide range of common and less-common filaments. <strong>For all details and considerations of the Satin sheet, please see <a href="http://help.prusa3d.com/article/satin-steel-sheet_196526">Satin steel sheet</a>.</strong></p>
<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"><strong>see our Material table</strong></a>.</p>

Flexible steel sheets (guidepost)

<p>An optional accessory for the Original Prusa MINI is <a href="https://shop.prusa3d.com/en/mini/1016-filament-sensor-mini-assembly.html">its filament sensor</a>. It uses a simple sensor mechanism to detect whether a strand of filament is inserted or not.&nbsp;</p>
<p>The mechanical lever that triggers the sensor, is attached by one M3x12 screw which is also its hinge. If this screw is tightened too much the sensor can be noisy or not trigger consistently.</p>
<h3>How to fix it</h3>
<p>The fix is to release the tension on the screw slightly. The hinge screw is accessible when the filament sensor is fully assembled and is the middle screw found on one side of the sensor (<span style="color: #b96ad9;">purple circle</span>). When tight, release the screw by <strong>one full turn, to one and a half turn.</strong> There should not be any resistance when inserting the filament.</p>

<h3>Testing the lever by hand</h3>
<p>If you need to test the movement of the lever (<span style="color: #2dc26b;">green arrows</span>), you can access the mechanism by removing the two M3x12 screws on each end of the sensor, which secures the cover (<span style="color: #236fa1;">blue circles</span>).&nbsp;</p>

One-click print

<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 stealth mode.</p>
<h3>MINI and MINI+</h3>
<p>The MINI/MINI+ is equipped with the TMC2209 motor drivers, where after multiple tests <strong>we have enabled StealthChop (Stealth mode) by default for X, Y, and Z-axis.</strong> The name Stealth mode comes from the MK3/S/+ and basically enables the same settings on its TMC drivers (StealthChop).</p>
<p>On the MINI+, <strong>the only exception is the extruder motor</strong>. Mainly due to the Bowden tube between the extruder and print head, it performs better and more reliably with the SpreadCycle enabled (that's the other mode of the TMC motor drivers).</p>
<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.&nbsp;</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 /&nbsp;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>
