@jay_s_uk hello! removed it, thank you very much!

@phaedrux Today a tried to use another duet 2 wifi and now the printer works... I think the other board is broken... I'll try to use it with a duex so I can connect motors directly to it, I hope it will work. Thank you very much for your help!

@phaedrux

@nicolo17 I have ''Driver 4: over temperature warning, over temperature shutdown, phase A short to ground, phase B short to ground, standstill, SG min n/a'' because I removed this driver from the board because was burned during an old project

@hayseed_byte @Phaedrux Thank you! I tried to change speed and acceleration (now I put very low values) in config.g under "drivers" sectionandand I'm still getting the same error
This is my config.g section:

@phaedrux I tested now the old motors and I got the same error...

@phaedrux I'm using a 12V 33A psu, specifications of the motor: https://www.gotronic.fr/pj-451.pdf

@phaedrux hello, thank you very much for your reply!

This is a new build, but the board was used before in another printer with different motors, it's not new.

To verify the phases I used a multimeter, if I get resistance between 2 wires, that belong to the same phase, no continuity = different phase.

If I disconnect all the motors and I try to home x and y I get the same error

Hello. When I try to home for the first time x and y axis, I get '' motor phase A/B disconnected reported by <all> drivers''. I controlled crimps, connections (phases are connected in the right mode, I used the duet's wiki instructions), resistance of motors with a multimeter and everything seems good. I have a duet 2 wifi with 3.3 firmware version, a cartesian printer and using 42byghm810 stepper motor. What could I do to solve the error?

this is a part pf my config.g:

@jay_s_uk hello! removed it, thank you very much!

Hello, I'm using a duet 2 wifi board with the E1 driver burned. I don't use the E1 for my printer, but i get "short to ground reported by driver 4" error and the driver heats up... I tried to use "M569 P4 R-1", the error stopped appearing but the driver still heats up. How could I solve?
