motor phase A/B may be disconnected reported by driver(s) 0123
-
@phaedrux I'm using a 12V 33A psu, specifications of the motor: https://www.gotronic.fr/pj-451.pdf
-
@nicolo17 said in motor phase A/B may be disconnected reported by driver(s) 0123:
the board was used before in another printer with different motors
Can you test with one of those previously working motors?
-
@phaedrux I tested now the old motors and I got the same error...
-
You might check this thread:
https://forum.duet3d.com/topic/28498/phase-a-and-b-may-be-disconnectedI believe you're trying to make the motors go too fast for your supply voltage.

@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:
; Drives
M569 P0 S1 ; physical drive 0 goes forwards
M569 P1 S1 ; physical drive 1 goes forwards
M569 P2 S0 ; physical drive 2 goes backwards
M569 P3 S1 ; physical drive 3 goes forwards
M584 X0 Y1 Z2 E3 ; set drive mapping
M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation

M566 X100.00 Y100.00 Z5.00 E100.00 ; set maximum instantaneous speed changes (mm/min)

M84 S30I also share my M122 response, if it can help:

@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
-
Can you grab some close up well lit photos of the board, especially in the driver chip area?

You can try adding
M569 P4 R-1
to your config to disable that driver entirely. That may get rid of that error at least.As for the other driver errors I'm not sure. You've already tested with previously working drivers and the error persists.
From a software side the only two things I can suggest at this point is to try updating the firmware to 3.4.2 just to refresh everything.
https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.2/Duet2and3Firmware-3.4.2.zip
Next you can try connecting a single motor only and a fresh config set from the config tool.
Otherwise has there been any event that you can think of which may have caused some damage to the board?

@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!
