<ul>
<li>The available bandwidth to both the "bridge mcu" itself and all devices on the CAN bus is effectively limited by the CAN bus frequency. As a result, it is recommended to use a CAN bus frequency of 1000000 when using "USB to CAN bus bridge mode".Even at a CAN bus frequency of 1000000, there may not be sufficient bandwidth to run a <code>SHAPER_CALIBRATE</code> test if both the XY steppers and the accelerometer all communicate via a single "USB to CAN bus" interface.</li>
<li>A USB to CAN bridge board will not appear as a USB serial device, it will not show up when running <code>ls /dev/serial/by-id</code>, and it can not be configured in Klipper's printer.cfg file with a <code>serial:</code> parameter. The bridge board appears as a "USB CAN adapter" and it is configured in the printer.cfg as a <a href="#configuring-klipper">CAN node</a>.</li>
