Driver 0.1 error: phase B short to Vin

scribe

I'm starting to think my 6HC has something wrong with it. Whatever I plug in to Driver 0.1 twitches erratically and then I got the error "Driver 0.1 error: phase B short to Vin"
Today I started getting "Warning: 12V under-voltage event (9.5V)" but seemingly at random and it recovers.

I've visually inspected the board and nothing is obviously wrong. I don't think it is still under warranty. Should I replace the board or is there something worth trying first?

Can you share the results of an M122 report gathered after you've had one of these errors?

How's the power supply?

Have you checked cables and crimps?

Does the driver 0.1 error happen if you swap in a different motor?

Sorry for the slow response that was more difficult to collect than I thought it would be, thank you for looking this over.

The power supply seems to be ok, both visually and the voltage reported in the M122 command matches.

I replaced the with a new one cable to try and eliminate that, and both cables show the same behavior.

I grabbed a new stepper motor and the behavior persists.

I am struggling to get the M122 command after the error as the web interface and on-board seem to be in an infinite loop of displaying the error with a close button. Attached is M122 from right before it happens.
Is there another way I can try to capture the M122 after I hit the issue?

Thank you again.

@Phaedrux I've sent that all and I figure I can mark this as solved.

Thank you for your time @Phaedrux
