Problem with all axis/motors (D3Mini+extension board)
-
The printer was working, printing. During one of the printouts suddenly the drives stopped working. At the time I did nothing about it because it was nearing the time of moving and I did not want to start it. Then everything slipped, and now that I finally have time I set about getting it up and running.
That is, there was a failure, the printer in such a state stood protected for a good few months.
After starting it up, basically after checking a few obvious things - whether there was a short somewhere, whether there was power, whether the fuse blew - I immediately wrote here.If it is a UART issue then what is the prognosis?
-
Giving the board a blast with compressed air may dislodge anything that could be bridging a pin and causing a short. Worth a try.

I tried that at very begining. Even before writing here.I ran many tests tonight.
I unplugged everything from the board and plugged it in one by one - I didn't notice that anything had an effect.
I see that the motors sometimes respond. Sometimes. They don't move in the correct way - for example, they just whirl. But a piece move by jumping.
I could not find the correlation. I unplugged and tried to check each one individually - on each it happens - either it does not work at all or works completely incorrectly.Occasionally, from time to time, there is a message about a driver short circuit. But not every time. Happens with different drives.

@Maciek yep that looks normal

Ok I know at least it's a D3m board issue. I borrowed duet mini from a friend. I plugged everything in and powered it up - it works as it should :/.
So for sure something with the board

Are you using the same mini2 board with the new mini5+?
-
Yes its same board.
-
Are there any measurement points on the board where I can check if everything is OK?

@domzduzt I think you should start a new thread and give some more information.
