@chrismbp Are you sure it's the 12V LED that is blinking, not the STATUS LED? The 12V LED is usually amber, see https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Expansion_1HCL#led-indications

Usually the STATUS LED blinking signifies a CAN error, but can indicate other issues. See https://docs.duet3d.com/User_manual/Machine_configuration/CAN_connection#led-behaviour-and-error-codes

If you can have a look at these, and see if that helps. If not, can you send a picture of the board?

@chrismbp Whenever you get an unexpected crash, please make sure to run M122 as soon as possible, and post the response. This usually can give valuable troubleshooting info. As you're using SBC, the system log may also be useful. Without these, it's difficult to know what might have happened.
