Sample G-codes

<p>On the <strong>Prusa CORE One</strong>, <strong>Original Prusa MK4/S</strong>, <strong>MK3.9/S</strong>, <strong>MK3.5/S</strong>, and <strong>XL</strong>, the firmware is flashed using a USB flash drive. This is valid for all ways of firmware updating. </p>
<h3>Offline USB Drive procedure</h3>
<ol>
<li>Download the latest firmware for your printer and extract it (zip file) on your computer
<ul>
<li><a href="https://help.prusa3d.com/tag/core-one">Prusa CORE One</a></li>
<li><a href="https://help.prusa3d.com/tag/mk4s">Original Prusa MK4S</a></li>
<li><a href="https://help.prusa3d.com/tag/mk4">Original Prusa MK4</a></li>
<li><a href="https://help.prusa3d.com/tag/mk3-9s">Original Prusa MK3.9S</a></li>
<li><a href="https://help.prusa3d.com/tag/mk3-9">Original Prusa MK3.9</a></li>

<li><a href="https://help.prusa3d.com/tag/mk3-5">Original Prusa MK3.5</a></li>
<li><a href="https://help.prusa3d.com/tag/xl">Original Prusa XL</a></li>
</ul>
</li>
<li>Make sure the USB flash drive doesn't contain any previous firmware (.bbf file)</li>
<li>Copy the new .bbf file to the root directory of a USB flash drive (Not within a folder).</li>
<li>Insert the USB flash drive and push the reset button<strong>.</strong> The bootloader will automatically compare the installed version with the one on the drive and, if it is newer, will automatically offer you to flash it. </li>
<li>Confirm the update by selecting the "FLASH" button and pressing the knob. </li>
</ol>
<p>If you need to downgrade the firmware or re-flash the same firmware, follow this guide: <a href="http://help.prusa3d.com/article/how-to-downgrade-firmware-mk4-s-mk3-9-s-mk3-5-s-xl_725930">How to downgrade firmware</a>.</p>

<h3>OTA (Over-The-Air) firmware update</h3>
<p>If your printer is connected to <a href="https://help.prusa3d.com/article/prusa-connect-and-prusalink-explained_302608"><strong>Prusa Connect</strong></a>, an over-the-air firmware update is also possible. </p>
<div class="tip-callout">It is still necessary to have a USB drive connected to the printer! </div>
<p>Prusa Connect checks the printer’s firmware version and offers you an option to remotely update it if a newer version is available. Click on the orange arrow icon to open a new window, with the option to transfer the new firmware file to the USB drive inserted in the printer. </p>
<p><img decoding="async" style="display: block; margin-left: auto; margin-right: auto;" src="https://cdn.help.prusa3d.com/wp-content/uploads/2025/01/89fe9b29dc6ebf11e2f94715e062bcdd.jpg" sizes="(min-width: 1024px) 820px, 100vw" srcset="How to update firmware (CORE One)" alt="" width="500" height="500" loading="lazy" /></p>
<h3>Factory Reset</h3>
<p>If you do a <strong>hard</strong> <a href="http://help.prusa3d.com/article/factory-reset-core-one-mk4-s-mk3-9-s-mk3-5-s-mini-xl_421206"><strong>Factory Reset</strong></a>, it is necessary to insert a USB drive with a firmware file. This firmware file is installed in the printer, so this can be used as a way to update the firmware. </p>


How to update firmware (CORE One, MK4/S, MK3.9/S, MK3.5/S, XL)

<p>The Original Prusa FFF printers and upgrades use a screw(s) with a spring(s) to provide tension between the filament and the filament pulley. It is important to have this tension correct. If too loose the pulley will not be able to "grab" the filament, while if it is too tight the extruder motor can overexert itself and even start grinding the filament. With the exception of the MK2/S and MMU1, the correct tension remains the same across all of our printers. </p>
<div class="note-callout">When printing flexible filaments (TPU/TPE) you want the screw even looser than what is depicted here. Please see <a href="http://help.prusa3d.com/article/flexible-materials_2057">Flexible materials</a> for more information.</div>
<h3>CORE One, MK4/S, MK3.9, XL</h3>
<p>The Prusa <strong>CORE One</strong>, and the Original Prusa <strong>MK4/S</strong>, <strong>MK3.9/S</strong>, and <strong>XL</strong> have two idler screws, that are inserted into the Idler Nut. The Idler Nut keeps the Idler, the part that includes the two driven gears, in place. <strong>The <span style="color: #e67e23;">tips</span> of the <span style="color: #236fa1;">screws</span> must be aligned with the front surface of the Idler Nut</strong>. </p>

<h3>MK3/MK2.5</h3>
<p>This extruder design has two idler screws. <strong>The head of the screw should be about flush to sticking out 1 - 1.5 mm when a filament is loaded.</strong></p>

<h3>MK2S</h3>
<p>The Original Prusa MK2S had a different extruder design. It has two screws, where the length of the springs <strong>should be circa 13 mm when tightened</strong>. After some use, it is ok to tighten them a little bit more, but the two screws must be equal.</p>

<p>Every Original Prusa printer has a unique serial number assigned to it. This is found on a silver sticker on every machine and is also hardcoded to the main controller board. Serial numbers issued before November 2021 start with "<em>CZPX</em>", while after November 2021 we introduced a new format starting with "SN". All serials are registered in our internal database and they allow us to confirm your printer as genuine.</p>
<div class="tip-callout">For some printer models, placing the serial sticker on the frame is part of the <a href="http://help.prusa3d.com/guide/8-electronics-assembly_174100#175963">assembly process</a>!</div>
<div class="note-callout">The best way to reference your printer is the <strong>order number</strong> you received when purchasing the printer. This can be found on the invoice or in <a href="https://www.prusa3d.com/account/orders/">your order-history in the eshop</a>.</div>
