Short to ground on drivers 0123

@Phaedrux Thanks for your reply.
No, I didn' unplugged the motor when it was powered on ( it is not my first printer build).
I'll post photos following your advice.

I forgot to mention that the error message is present without the motors plugged ...
It is the Duet3 V1.01Here is a photo of the plug. I tested the phase before plugging it.
Tape is provisory.

that would unfortunately indicate the drivers/mosfets are damaged

Tha would explain why I'm loocking for a solution since 2 days ....

Are you using an Hemera hotend? If so then they have some really weird wiring with the last two pins swapped. So Black - Red - GREEN - BLUE.
I've just read your second comment. If it happens with no stepper plugged in then this hints at you've blown your board.
-
@StevePS3 No, I'm at the beginning building process

there isn't really any standard to follow, so it can't really be weird. the guide will work regardless of colours.

I tested phases and continuity in wires and pairs are correct.

@bearer
Is there not? OK, Every other stepper I've ever used (not that many) has always been B-G-R-B.In that case ignore me

I don't know whhat to do because I tried to swapped wires many times.
one wrong combination where you let one side of the h bridge drive against the other is enough to cause this issue.

On every drivers and without plugged motors ?

driver 5 and 6 are okay arent they? and yes, the error will persist after unplugging the motor if you got the "correct" wrong combination.

I didn't test the 5 and 6 drivers yet. I reflashed and erase everything to test again but always the same message.
With my Duet2 wifi, it worked before -
I think we can leave it at drivers 0-3 are damaged, and Duet people will determine the cause and potential remedy.
(edit:
shop will tell you to get Duet people to determine the cause, on this fourm) -

Ok I contacted the shop and see what we can do .
Thanks for your help -

Unfortunately, swapping stepper motor wires over so that they are no longer wired with one phase to each end of the connector is a recipe for blowing drivers. This is because the driver cannot control the output current when they are mis-wired in this way. Sometimes they survive, sometimes they don't - it depends on the VIN voltage and the type of motor.

@dc42 ok I understand but the problem was present at the first plug and I used the same working wiring than my working Duet2. And the message was telling that the driver 1 was short - ground and I had never plugged anything on the socket.
I repeat, I swapped the wires because it didn't work with the same wiring as my Duet2. -

Tape is provisory.
What role does the tape play there? Is it possible the crimp was bad from the start and making a bad connection?
Were you getting the error before plugging anything in or only after?
-
@Phaedrux Tape is only a protection to avoid shorts contact. Contacts were good since I made continuity tests and resistance tests and I always had signal.
-
Were there any other error messages along with the short to ground errors?
