oops my printer fell from the table

ageis

Yeah i didn't put it flat and it fell. Now I get an error on driver 2

Driver 2 error: phase B short to ground

I have two question which driver ic is driver 2?

584 X0 Y1 Z2 E3                               ; set drive mapping

Am guessing that this tell reprap which axis is connected to which driver.

In an attempt to see if it's the board thats damaged, I have disconnected all motors then tried homing. I still get the same error on driver 2.

Does this mean it's fried?

@ageis Driver 2 on a Duet 2 WiFi is the Z driver. If the printer fell off the desk, it could be the Z axis moved at fast speed, and blew the driver, or it could have just suffered damage. It looks like you still have driver 4 (E1) free, so you could move the Z axis to that. You can disable the driver and stop it reporting the error in config.g. So it will look something like this:

; Drives
M569 P0 S1                                     ; physical drive 0 goes forwards
M569 P1 S1                                     ; physical drive 1 goes forwards
M569 P2 R-1                                     ; physical drive 2 is disabled
M569 P3 S1                                     ; physical drive 3 goes forwards
M569 P4 S1                                     ; physical drive 2 goes forwards
M584 X0 Y1 Z4 E3                               ; set drive mapping

Post a good photo of the board around the Z driver area, and we'll look to see if there's any obvious damage.

Did the jumper on the second Z driver port get dislodged?

@Phaedrux
I have replaced the jumpers on the second connector. I didn't connect the motor to the board
I still get the same error message.

I think it's likely the fall killed the driver because it also broke the mount that mounts the motor onto the frame. Like @droftarts said it may have forced it upwards at speed and killed the driver.
