<p>The First Layer Calibration is used to calibrate the distance between the tip of the nozzle and the print surface. The aim is to adjust the nozzle height until the extruded plastic sticks nicely to the bed and you can see that it is being slightly squished.</p>
<p>The printers assembled in the Prusa factory are already fine-tuned and this calibration is needed only in case you build the kit version at home or change the nozzle. The First Layer Calibration is part of the Wizard (last step of the XYZ-Calibration). You can also recalibrate the first layer later on from the <em>LCD-menu - Calibration - First Layer Calibration</em>. During this process, rotate the knob to manually adjust the distance between the nozzle and the bed, while the printer is printing a zig-zag pattern.</p>
<div class="warning-callout">As <strong>each type of sheet (smooth, satin, and textured) has a different thickness</strong> you must use a different First layer calibration for each of them. For this, we have a convenient feature called <a href="http://help.prusa3d.com/article/steel-sheet-profiles_1955">Steel sheet profiles</a>.</div>
<p>With a newly assembled printer, you will start at zero and move into a negative (-) value, reducing the distance between nozzle and heat bed. The initial zero-value is set by the P.I.N.D.A./SuperPINDA. position. <strong>Turn the knob counter-clockwise to bring the nozzle closer to the bed and moving the value away from zero. </strong>The value is unique to each printer and it may also slightly change with time and use. You must, therefore, <strong>check visually when adjusting the height, not by a set value. </strong></p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/first_layer-768x433-1.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/first_layer-768x433-1-600x338.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/first_layer-768x433-1-300x169.jpg 300w" alt="" width="600" height="338" loading="lazy" /></p>
<p>The first layer calibration being set incorrectly can lead to various issues. With the nozzle too far from the print surface, you risk your print not sticking properly, which can result in a <a href="http://help.prusa3d.com/article/extruder-blob_2005">blob</a>. On the other side, if set too close, you can experience extrusion problems and <a href="http://help.prusa3d.com/article/clogged-nozzle-hotend-mk3-5-s-mk3s-mk2-5s_2008">clogging</a> and poor print quality, <strong>or even damage to the hardware, like the <a href="http://help.prusa3d.com/article/flexible-steel-sheets-guidepost_2195">Flexible steel sheet</a> due to the print sticking too much.</strong> It is therefore <strong>important to get this right.</strong></p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-01.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-01-300x62.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-01-600x125.jpg 600w" width="600" height="125" loading="lazy" data-hd-align="center" /></p>
<p>Before you proceed, make sure that the print surface (satin, smooth, or textured steel-sheet) is clean. You can find information on how to clean it in <a href="http://help.prusa3d.com/article/first-layer-issues_1804">PEI print surface preparation</a>. There are some small differences between how it should look on the textured and smooth steel sheet. We will, therefore, present pictures and guidelines for both, starting with the smooth sheet.</p>
<div>
<div class="note-callout" style="text-align: center;"><strong>Turn the knob counter-clockwise to bring the nozzle closer to the bed.</strong></div>
</div>
<h3>Smooth sheet</h3>
<h4>Too high</h4>
<p><strong>You want the line flattened, but not squished.</strong> On the square at the end of the test line, you do not want any <strong>gaps between the lines (<span style="color: #e03e2d;">left picture</span>), which means it is too high. </strong>In that case, the value will be too close to zero</p>
<h4>Too low</h4>
<p>If the nozzle is set too low (<span style="color: #e03e2d;">right picture</span>) you will see the line squished completely flat and the end square will have <strong>ridges between the lines, which is a clear sign it is set too low</strong> and the value will be too far away from zero. When it is too low, the edges of the square can also start curling upwards. In the extreme, the filament will be spread so thin you will be able to see through the printed filament, leading to clogging of your hotend.</p>
<div class="warning-callout">Having the nozzle too low can cause the nozzle to damage your steel sheet. This is not covered by <a href="http://help.prusa3d.com/article/warranty_2288">Warranty</a>.</div>
<h4>Just right</h4>
<p>A correct adjustment will show you an even surface (<span style="color: #2dc26b;">center picture</span>), with no gaps between lines, nor ridges. As stated, the numeric value depends on the exact position of the P.I.N.D.A./SuperPINDA sensor, which will be unique to each machine and means nothing without a visual reference. <strong>However, a common range is from -0.400 to -1.500.</strong></p>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-02.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-02-300x119.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-02-600x238.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-02-768x305.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-02-800x318.jpg 800w" /></p>
<div class="note-callout">Adjusting it closer can in some cases improve adhesion. However, if you are having problems with adhesion, but your first layer calibration looks like the 'good' picture (<span style="color: #2dc26b;">center picture</span>), your problem lies somewhere else, like a dirty/greasy sheet, print-settings, bed leveling/XYZ calibration, or under-extrusion.</div>
<p><img decoding="async" src="https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-03fix-2.jpg" sizes="100vw" srcset="https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-03fix-2-600x214.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-03fix-2-800x286.jpg 800w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-03fix-2-300x107.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-03fix-2-768x274.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-03fix-2-1536x548.jpg 1536w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-03fix-2-2048x731.jpg 2048w" alt="" width="1121" height="400" loading="lazy" /></p>
<div class="warning-callout"><strong>You can not use the same first layer calibration if you swap between the Smooth and the textured sheet! </strong>For more information, please see <a href="http://help.prusa3d.com/article/steel-sheet-profiles_1955">Steel sheet profiles</a>.</div>
<h3>Textured sheet</h3>
<p>The textured sheets are thinner than the sheets with smooth PEI, therefore you need to move the nozzle bit closer, but you are seeking the same results as with the smooth sheet. Again, if <strong>it is set too low (<span style="color: #e03e2d;">right picture</span>) the filament can start curling up</strong> around the edges like it is not adhering. The numeric value will be too far from zero and must be adjusted back.</p>
<p>If set too high, you will see the line being round, and have gaps between the lines of the end-square. In this case, the value is too close to zero.</p>
<p><img decoding="async" title="https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-04-300x119.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-04-600x238.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-04-768x305.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-04-800x318.jpg 800w" src="https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-04.jpg" /></p>
<h3>Have a look at the nozzle</h3>
<p>A single layer is about 0.2 mm / 0.00787402 inch. Having a look at the nozzle and its distance to the sheet can also be helpful. However, measuring the printed layer with calipers is not a recommended method to calibrate the first layer.</p>
<p><img decoding="async" title="https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-05-300x119.jpg 300w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-05-600x238.jpg 600w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-05-768x305.jpg 768w, https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-05-800x318.jpg 800w" src="https://cdn.help.prusa3d.com/wp-content/uploads/First-Layer-Calibration-05.jpg" /></p>
<h3>When to run the First layer calibration</h3>
<p>Generally, the <strong>first layer calibration</strong> should be performed every time there is a <strong>major change in the assembly.</strong> This includes changing the nozzle, extruder upgrades, or other updates to any axis. You should also run all calibrations if you move the printer to a different location.</p>
<div class="tip-callout">For First Layer Calibrations with other nozzle diameters than 0.4 mm, please see <a href="http://help.prusa3d.com/article/different-nozzle-types_2193#first-layer-calibration-of-other-nozzles">this article</a></div>
<h3>Other issues</h3>
<ul>
<li>If the width of the line varies across its length, you may have to do some <a href="http://help.prusa3d.com/article/bed-level-correction_2267">Bed Level Correction</a>.</li>
<li>If the nozzle comes in contact with the bed, the SuperPINDA/P.I.N.D.A. leveling sensor is not being triggered by the flexible steel sheet and must be physically moved lower in its holder. This will bring it closer to the level of the nozzle tip. You should make sure it is adjusted as instructed in the <a href="http://help.prusa3d.com/guide/9-preflight-check_76792">Preflight check</a> in the Assembly manual. <strong>If you move the leveling sensor you must redo the First layer calibration.</strong></li>
</ul>

In other words, the&nbsp;<strong>Extrusion Multiplier</strong>&nbsp;setting in PrusaSlicer and the&nbsp;<strong>Flow rate</strong>&nbsp;setting in printer firmware are two ways to adjust the same thing, however, adjusting one of those two settings will not influence the value of the other.</p>
<p><strong>This procedure is not necessary with a new printer coming from the factory</strong>, but rather applies for specific applications and filaments. The ideal value is different for every type of material and every color. It can even differ from spool to spool. Bear this in mind if you change type and brand of filament often or use cheap no-name brands.</p>
<div class="note-callout">Total flow rate = <strong>Flow multiplier</strong> in firmware (M221) x <strong>Extrusion multiplier</strong> in PrusaSlicer. For those interested in diving deeper, PrusaSlicer uses the same <a href="https://manual.slic3r.org/advanced/flow-math">Flow math as Slic3r</a>.</div>
<h3><strong>How to spot an issue</strong></h3>
<p>This calibration is used to fix two common problems:</p>
<ul>
<li><strong>Overextrusion</strong> - Too much material is extruded (flow is too high). It causes scarring of bottom layers and unnecessary material buildup on top layers.</li>
<li><strong>Minor under extrusion</strong>&nbsp;- Not enough material is extruded (flow is too low). It causes small gaps that appear between layer lines or perimeters.</li>
</ul>

<p><strong>Overextrusion</strong> is a common problem with many filament brands. It's especially problematic when you're trying to glue two parts of the model. <strong>If the top layer is over extruded, you'll end up with an uneven surface that will prevent a seamless connection between the two pieces.</strong></p>
<h3><strong>How to do the calibration</strong></h3>
<p>In PrusaSlicer, navigate to <span class="key">Filament Settings</span> and look for Extrusion Multiplier. The default setting (for PLA) is 1, this value represents a percentage, 1 = 100%, 0.95 = 95% etc. Usually, the adjusted values can be between 0.9 and 1.1. To adjust it, simply rewrite the value.</p>
<p><img decoding="async" style="max-height: 200px; display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/prusuki/prusuki-images/image-2019-1-15-12-55-6.png" data-hd-height="200px"></p>
<p>In the printer menu, during a print, go to the Tune menu and then choose Flow. Again, the usual values can range between 90 and 110, although that does not mean you can't go above or below that.</p>
<h4>Which method should I use?</h4>
<p>There are two methods you can use to calibrate the Extrusion Multiplier, and we'll cover both of them in this article:</p>
<ul>
<li><strong>Precise Method</strong>&nbsp; -&nbsp; using precision tools such as calipers or micrometers.</li>
<li><strong>Visual Method&nbsp;</strong>&nbsp;- an easy method based on observing the visual properties of your models.</li>
</ul>
<p>The choice of the method depends entirely on your preferences; in the end, both yield similar results. Even the visual method will enable you to have perfectly fitting parts with smooth &amp; flat top layers.</p>
<h4>Precise Method</h4>
<div class="note-callout">Please note that the following guide is based on <strong>default</strong> PrusaSlicer 0.4 nozzle profiles, with a layer height of 0.1mm - 0.2mm. This means that:<br />
- Nozzle size = 0.4<br />
- Extrusion width =&nbsp;0.45<br />
- Basic materials (PLA, ABS, PETG) Extrusion Multiplier = 1<br />
<strong>If you wish to calibrate the printer with a bigger/smaller nozzle or layer heights above 0.2, then you will need to adjust these values as well.</strong></div>
<ol>
<li>Download the <a href="https://cdn.help.prusa3d.com/wp-content/uploads/2021/04/cube-40-40-40.zip">Precision Method Cube STL</a>.</li>
<li>Slice it using the Vase Mode and your most-often used layer height and print it. You can find Vase mode (Print Settings →&nbsp; Layers and perimeters →&nbsp; Spiral vase).</li>
<li>Make three or more measurements in the middle of each wall and calculate the overall average thickness.</li>
<li>Calculate the extrusion multiplier using the following formula: <strong>Extrusion multiplier = (Extrusion width (0.45) / Average measured wall thickness)</strong>.</li>
<li>Adjust the Extrusion Multiplier in Filament Settings → Filament</li>
<li>Re-print the cube with new settings and go back to step 3 if necessary.</li>
</ol>

<div class="warning-callout">Please note that cheap digital calipers may not be accurate enough to make reliable measurements of a single perimeter wall.</div>
<h4>Visual Method</h4>
<p>This method does not require any tools, only your sight. The point is to make sure your top layers are <strong>smooth</strong>, <strong>shiny,</strong> and without <strong>scarring or filament buildup</strong> near the perimeters.</p>

<li>Slice it using the default Prusa PLA presets at 0.20mm layer height and print it.</li>
<li>Inspect the top layer of your cube visually and with the tip of the finger.</li>
<li>If the top is under extruded or not smooth, then re-adjust the Extrusion Multiplier accordingly by 1-2%.</li>
<li>Repeat the steps above as long as needed.</li>
</ol>
<p>If there is&nbsp;<strong>too much material</strong>&nbsp;near the perimeters,&nbsp;<strong>decrease</strong>&nbsp;the Extrusion Multiplier value.</p>
<p><img decoding="async" style="max-height: 390px; margin-left: auto; margin-right: auto; display: block;" src="https://cdn.help.prusa3d.com/wp-content/uploads/prusuki/prusuki-images/buildu.jpg" data-hd-height="390px" data-hd-align="left"></p>
<p>If there are&nbsp;<strong>visible gaps</strong>&nbsp;between layer lines,&nbsp;<strong>increase</strong> the Extrusion Multiplier value. (Microscopic gaps near the perimeters are OK.)</p>

<h3>Basic info</h3>
<div><strong>PETG</strong> is one of the most easily printable materials, it is <strong>inexpensive and suitable for beginners</strong>. Relatively high tenacity and temperature resistance make it <strong>suitable for printing technical parts</strong> (for example parts of our printers).</div>
<div>&nbsp;</div>
<div><strong>Recommended nozzle temperature:</strong> 230 °C for the first layer, 240 °C for the other layers</div>
<div>&nbsp;</div>
<div><strong>Recommended bed temperature:</strong> 85 °C for the first layer, 90 °C for the other layers</div>
<div>&nbsp;</div>
<div><strong>Heatbed:</strong> Using powder-coated TXT or satin sheet is highly recommended. Printing on smooth PEI surface might damage the sheet.</div>
<h3>Description</h3>
<div>
<p><a href="https://www.prusa3d.com/category/prusament-petg/"><strong data-stringify-type="bold">PETG</strong></a> (Polyethylene Terephthalate modified with Glycol) is a commonly used technical material, popular among 3D printer users for its <strong>low price and good printability</strong>. It’s tenacious, with good temperature resistance; PETG is most commonly used for printing various mechanical parts, holders, clamps, and waterproof parts (thanks to great layer adhesion).</p>
<p>PETG has a glossy surface, adheres greatly to a print sheet, and <strong>does not shrink or warp</strong> (it has very little thermal expansion), therefore it’s suitable for printing large models. Plus, its high tenacity and flexibility often <strong>prevent it from breaking.</strong> Due to good temperature resistance, PETG parts are suitable both for interior and most exterior use (with temperatures below 80 °C). <strong>Parts of our printers are made of PETG!</strong></p>
<p>The letter G in PETG means that it’s modified with glycol during the manufacturing process. Glycol makes PET less brittle, easier to print, and more transparent for translucent prints. Of course, you can print also with PET filaments without glycol. However, printing with only PET is challenging and does not offer any advantage whatsoever.</p>
<div class="warning-callout">Even though PETG in itself may be considered <a href="http://help.prusa3d.com/article/food-safe-fdm-printing_112313">food-safe</a>, it consists of layers, as every 3D print, in which bacteria can grow over time. You can prevent this by applying a <strong>food-safe(epoxy) coating.</strong> Also, a stainless-steel nozzle should be used for if food is the intended application.</div>
<p>Although <strong>PETG</strong> is frequently used in <strong>food industry</strong> and is considered <strong>food-safe</strong>, we do not recommend it (or any other filament) for printing dishes or other stuff that comes into direct contact with food. The main reason is tiny print layer surface grooves that can support numerous bacterial colonies. But if you still want 3D printed dishes, we suggest <strong>applying a special layer</strong> that seals the surface (food-safe coating) and printing with a clean steel nozzle.</p>
<p>Some of the manufacturers <strong>enrich PETG with various additives</strong> and sell these materials under different names. For example, Spoolworks EDGE by E3D is modified PET/Copolyester Blend with additives. The goal is to acquire better visual qualities, surface and layer adhesion, etc.</p>

<h3>Best use</h3>
<p>PETG is used universally but is especially suitable for mechanical parts for both indoor and outdoor use. We use PETG to print parts for our printers! Plastic bottles are also made from this kind of material.</p>
<h3>Tips for successful printing</h3>
<p><strong>Temperature settings and cooling</strong></p>
<p>Unlike PLA, <strong>PETG requires a heated bed (85 °C).</strong> Its bridging- and overhang-behavior is usually worse, plus it is prone to stringing. Stringing can be moderated with higher retractions and lower nozzle temperature, but we suggest <strong>using the PrusaSlicer profiles that should work fine.</strong> It’s important to <strong>cool the PETG print</strong> - this helps to keep the model detailed and prevents stringing and oozing. But if you want the model to be as tough as possible, try to turn off the print fan. Higher filament temperature improves merging between layers which leads to better mechanical resistance. Otherwise, we recommend printing the first few layers with the print fan off to prevent deformation, then with the fan running at half its power.</p>
<div class="warning-callout"><strong>Do not print on the smooth PEI sheet</strong> as the adhesion may be too strong!</div>
<p><strong>Print surface preparation</strong></p>
<p>Make sure the print surface is clean, as described in <a href="http://help.prusa3d.com/article/first-layer-issues_1804">our dedicated article</a>. It is advisable to use one of the <strong>powder-coated print sheets. Do not print on the smooth PEI sheet</strong> as the adhesion may be too strong! If you decide to use the smooth PEI sheet anyway, apply a glue stick on it before printing.</p>
<p><strong>Adding more perimeters for more solid parts</strong></p>
<p>If you want to print truly solid parts, <strong>try to increase the number of perimeters</strong> instead of adding more infill.</p>
<h3>Postprocessing</h3>
<p>PETG can be easily sanded both dry and wet.</p>
<p><strong>Dissolving PETG</strong></p>
<p><strong>Dissolving and smoothing PETG</strong> is possible only in a laboratory by skilled lab workers using <strong>dangerous chemicals</strong> (Dichloromethane).</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>Next-gen Original Prusa printers</h3>
<p>Such as the<strong> MK4/S, MK3.9/S, MK3.5/S, XL, MINI/+, SL1/SL1S </strong> as well as the other upcoming models have the PrusaLink built-in. You can connect the printer either using Wi-Fi or a wired LAN (Ethernet) network. Note that on MINI/+, you have to first <a href="http://help.prusa3d.com/guide/installing-wi-fi-and-prusalink-mini-_316781">install the Wi-Fi module</a> to use the wireless functionality.</p>

<p> </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)

<h3>What happened? </h3>
<p>During the configuration of <strong>Prusa Connect</strong> on the <strong>Original Prusa MINI/+</strong>, <strong>MK4/S</strong>, <strong>MK3.9/S, MK3.5/S</strong> or <strong>XL</strong> an error on this configuration can occur and the printer shows the message "<strong>Registration to Prusa Connect failed due to: ~</strong>". In place of <strong>~</strong>, a text with more details is shown, from the list below. Depending on the specific shown text, there are different causes and fixes. </p>
<p>Error name: Connect Registration Failed</p>
<p>Error code: #12401 (MINI), #13401 (MK4), #26401 (MK4S), #21401 (MK3.9), #23401 (MK3.5), #17401 (XL)</p>
<h4>DNS error</h4>
<p>The printer wasn't able to resolve the <strong>hostname</strong> of the Prusa Connect server into an IP address. The hostname is a unique label assigned to a device connected to a network. </p>
<ul>
<li>The printer is not connected to the network at all.</li>
<li>In case of a <strong>static</strong> configuration (non-DHCP), the <strong>DNS server</strong> is not configured or configured incorrectly.</li>
<li>The local DNS server is currently not working.</li>
<li>The Connect hostname is reconfigured to some that doesn't exist. For example, this can occur if loading a .ini file with an invalid configuration.</li>
</ul>
<h4>Refused</h4>
<p>It's not possible to reach the server on the network level, hence it is not possible to establish a TCP connection. The system is either not answering at all or actively refuses the connection. </p>
<ul>
<li>The internet connection is not working, or a firewall blocks the communication.</li>
<li>In the case of a <strong>static</strong> configuration (non-DHCP), the <strong>gateway </strong>(typically, this is the IP address of the router) is not configured or configured incorrectly. </li>
<li>The Connect server is under maintenance. </li>
<li>Too many TCP connections are open with the printer, for example in PrusaLink. </li>
</ul>
<h4>TLS error</h4>
<p>This message points to an error doing a <strong>SSL/TLS handshake</strong>. This handshake is the process to create a safe and encrypted connection. </p>
<ul>
<li>Time is not synchronized on the printer (MINI/+). The time synchronization occurs for each internet connection, through the <a href="http://help.prusa3d.com/article/ntp-server-mini_151132">NTP server</a>. It is possible this might take more time than initially expected, or rarely, that there might be issues with the server. </li>
<li>A restrictive firewall (for example but not limited to a corporate proxy firewall) may restrict an automatic access to the NTP server. In that case, it will be necessary to manually allow the printer to access the NTP server.</li>
<li>Something in the path is trying to tamper with the communication, for example but not limited to an attack. </li>
</ul>
<h4>Unauthorized</h4>
<p>The server claims that the printer is not authorized. The printer is not recognized as an Original Prusa. </p>
<h4>Server error</h4>
<p>The server is returning a <strong>500 Internal Server Error</strong> or similar. The issue is on the Connect side, and is expected to be fixed on its own. </p>
<h4>Internal error</h4>
<p>This error is caused by an issue related to the printer firmware. </p>
<h4>Network error</h4>
<p>Similar to the Refused error, but the connection dropped after it was initialized. </p>
<ul>
<li>Glitchy internet connection.</li>
<li>The <strong>latency</strong> to the Connect servers is too high. A geographic location is very far from our Connect servers can contribute to this cause.</li>
<li>The Connect server is temporarily down.</li>
</ul>
<h4>Protocol error</h4>
<p>The response from the server is not recognized.</p>
<ul>
<li>Bug on the server side. This cause is on our side and expected to be fixed on its own. </li>
<li>Too old firmware on the printer and it's no longer supported.</li>
<li>A misconfiguration from the <strong>.ini file</strong> loaded on the printer, connecting to something different than our Connect server.</li>
</ul>
<h3>How to fix it? </h3>
<h4>DNS error, Refused</h4>
<p>Ensure that the printer is connected to the internet. In case of a static (non-DHCP) connection, ensure the correct settings are there, or test a DHCP connection. Also, check the .ini configuration file, and in case, rewrite the file. </p>
<p>If the previous steps didn't fix the issue, attempt a <a href="http://help.prusa3d.com/article/factory-reset-mini_177516">factory reset</a>. </p>
<h4>TLS error</h4>
<p>Reattempt the Connect registration, after the printer is connected to the internet for a few more minutes. </p>
<p>If the previous step didn't fix the issue, double-check your network <strong>firewall</strong>. Some firewalls will need for the NTP server to be allowed manually. The specific steps will depend on your specific firewall, we recommend checking your firewall documentation. </p>
<h4>Unauthorized</h4>
<p>If your printer is not an Original Prusa printer, it cannot use our Prusa Connect service.</p>
<p>In case your printer is an Original Prusa, <a href="http://help.prusa3d.com/article/firmware-updating-mini-mini_124784"> re-flash or update its firmware</a>. </p>
<h4>Server error</h4>
<p>A server error indicates an issue from our side. The issue will be fixed on its own, try registering again to Prusa Connect later. </p>
<h4>Internal error</h4>
<p><a href="http://help.prusa3d.com/article/firmware-updating-mini-mini_124784">Re-flash or update the printer firmware</a>. If this does not solve the issue, take note if the printer might have other issues, even if not directly related. </p>
<h4>Network error</h4>
<p>Ensure that your internet connection is stable and not glitchy. To confirm whether an inconsistent internet connection caused the issue, test another connection, if available, such as a hotspot from your mobile phone. </p>
<h4>Protocol error</h4>
<p>Ensure that the printer is running our latest firmware version. If it is running an old version, update the firmware. Also, check the .ini configuration file, and in case, rewrite the file.</p>

Prusa Mobile App

<div class="warning-callout">This article is intended for experienced users only!</div>
<p>When using <strong>PrusaLink</strong>, you connect to your printer via its <strong>IP address</strong>, which is assigned to it by the<strong> DHCP</strong> server on your network. Sometimes, if your printer disconnects and reconnects, it may receive a different IP address from the DHCP server. This can cause connection issues if you're trying to access the printer using its previous IP address, which is no longer valid.</p>
<h4>How to solve it?</h4>
<p>Set your router's DHCP to consistently assign the same IP address to a device based on its MAC address.</p>
<p>The MAC address is available in the menu <strong>System &gt; Network</strong>. Note that it differs for the Ethernet or the Wi-Fi.</p>
<p>This alone should be enough to prevent the IP address from changing over time.</p>
<p>Furthermore, you can set up your printer to use a static IP address instead of requesting to be given the IP Address from the DHCP server. </p>
<p>To set a static IP address on the printer, you can enter the IP address, network mask, gateway, and specify the DNS server in the prusa_printer_settings.ini configuration file:</p>
<p> </p>
<p>[eth::ipv4] <br />type=static <br />addr=192.168.0.42 <br />mask=255.255.255.0 <br />gw=192.168.0.1 </p>
<p>[network] <br />dns4=1.1.1.1;8.8.8.8</p>
<p> </p>
<p> </p>
<p>Copy this file to a USB drive and upload it to the printer via the menu <strong>Settings &gt; System &gt; Load Settings from File</strong>. This will load all the settings from the .ini file. (Note, this is a different menu than "load settings" for Wi-Fi settings, which only uploads Wi-Fi data.) Afterward, restart the printer.</p>
<p>Be careful, you need to reserve the given IP address in the router's settings for the printer to avoid potential IP address conflicts.</p>
<p>For setting a static IP address for Wi-Fi instead of the Ethernet, the process is exactly the same, but instead of [eth::ipv4] use [wifi::ipv4].</p>
