The machine screen displays the following error:
Hub board not detected: This means the Hub board was not powered on during system startup.

Hub board connection interrupted: This means the Hub board was powered on normally during system startup, but it suddenly lost power after the system started.

Under normal circumstances, when the 0003-0522-0101-0006 / 0003-0522-0100-0008 error occurs, the toolhead's internal indicator light will still turn on:
In rare cases, if all toolheads suddenly lose power after system startup, this will be indicated by all toolhead internal indicator lights being off, and the 0003-0522-0100-0008 error will also appear.
If you encounter this situation, please refer to No Toolhead Detected to troubleshoot the issue.
