Driver Errors Duet2 Railcore 3D Printer

MKMachining 0 · 30 Mar 2022, 18:00

My duet2 recently was broken so i had it replaced with a new one. After setting it up with the up to date configuration there was an error that kept showing up with the drivers.
"Driver 1 error: over temperature shutdown, phase B short to ground"
"Driver 2 error: over temperature shutdown"
and others in that variation

Here is the Diagnostics

Please post your config.g and the results of M98 P"config.g"

Are the driver chips themselves hot?

Do the errors remain if you disconnect all of the motors (when the board power is off)?

@phaedrux

Yes the chips do seem to be hot and there are no errors when I turn the machine on without the motors connected

Phaedrux · 30 Mar 2022, 19:16

Overtemp shutdown would mean too hot to touch for more than a second.

Do they still get hot when motors disconnected?

MKMachining 0 · 30 Mar 2022, 19:18

@phaedrux

They do not when the motors are disconnected

Phaedrux · 30 Mar 2022, 19:21

Then I would double check that your motor wiring is correct.

Are you using a Duex as well? Can you test the drivers there?

Has anything changed recently on this printer?

MKMachining 0 · 30 Mar 2022, 19:29

@phaedrux

Yes it is using a duex, how would I test the drivers from there?

The board we had before failed, it was working fine for a few years. The wiring is the same as before, the main visible damage was on the MicroSD card

Phaedrux · 30 Mar 2022, 19:38

So this is a new board? Has it ever worked?
Do you know what the cause of the previous failure was? Seems like a pretty bad short. Was the cause corrected?

I fear history may be repeating.

MKMachining 0 · 30 Mar 2022, 19:44

@phaedrux

This board has only been hooked up for a couple of days now.

We are not entirely sure what the cause of the previous short was. Like I said earlier this printer was running fine for quite a few years. It happened when there was an issue with the "always on" port that was being test. It smelled like something was burning which was found to be the SD card. I'm not sure how testing that caused such a big reaction.

Phaedrux · 30 Mar 2022, 19:45

I think you need to closely inspect the wiring and the board and surrounding area. Something seems to be shorting. Are you able to test the motors in another printer? I fear that whatever caused the previous damage is still present.

MKMachining 0 · 30 Mar 2022, 19:49

@phaedrux

Yes there are other printers that could test the motors. Do you have any suggestion on how to go about this?

connect the motor to the other printer and configure them appropriately and see if they work correctly there or not.

elmoret · 30 Mar 2022, 23:45

That SD card damage looks to me like something is shorting +3.3v to a 5v or 24v rail...

MKMachining 0 · 4 Apr 2022, 15:31

@phaedrux

I tried the motors on a different working printer which then showed the same errors.

I then put working motors on the broken printer, the motors then read the same short error

Could it be and issue with the power supply?

After some time the errors do occur with the disconnected motors

Phaedrux · 4 Apr 2022, 18:34

So you tried the motors from your railcore on a different printer and it had the same overtemp/short to ground errors?

And new motors on the railcore had the same as well?

It sounds like you've had a pretty significant short that has maybe damaged the coils of the motors and damaged the drivers.

As I said before, I think you need to closely inspect the wiring and the board and surrounding area. Something seems to be shorting. And I think some damage has already been done.

Can you post some close up well lit photos of the duet? There may be some damaged chips.
