Hi, I have two identical Glowforge Plus. One of the MBs has a problem and I have tried swapping the MB between the two units. The error stays with that defective MB and the GF will be stuck on “Scanning” with a red light on in both GFs. The other MB works in both GFs with no error.
I have tried to analyze the logs and find the following error on that bad MB. Please remember, that shows up in both the units, when I have the bad MB.

Has anyone ever seen this ?
According to the HW reenginieering document Pin 1 of the power supply connector seems to have this signal: HV Current TP_B2F
