<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-mk3-9-mk3-5-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>
<ul>
<li>For more info on <strong>how to connect a camera</strong>, visit the<strong> <a href="http://help.prusa3d.com/guide/camera-setup-for-prusalink-prusa-connect_470943">Camera setup for PrusaLink / Prusa Connect</a></strong> article.</li>
<li>For more info about Prusa remote connectivity services, visit the <strong><a href="http://help.prusa3d.com/article/prusa-connect-and-prusalink-explained_302608">Prusa Connect and PrusaLink explained</a> </strong>article.</li>

<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>

Camera compatibility (RPi + PrusaLink)

<h3>What happened? </h3>
<p>During the configuration of <strong>Prusa Connect</strong> on the <strong>Original Prusa MINI/+</strong>, <strong>MK4</strong>, <strong>MK3.9, MK3.5</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), #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>
