@phaedrux Yes. Yesterday I also tried to move the steppers with arduino with motor shield and they work.

@droftarts
I bought the plate on March 31 from my local retailer. I was very satisfied because the only reseller in Poland is a few hundred meters from me and is on the Duet3D list

Maybe it' s possible to check SPI through RaspberryPi ports, I have several Pi Zero. @dc42

@droftarts
Fuses are ok.

When I manually move the engines no message appears.

Yes, the DWC shows the motor position incremented by the desired value but the motor does not move at all.

I disconnected everything except power supply, stepper motor and power cable - still nothing.

@phaedrux The pins are in contact with the motor. I checked with a multimeter on the underside.
It doesn't work on other ports either.

@alankilian All diodes are lit.

Are the components marked in yellow not broken because they look a little different than the ones next to them (red)

@alankilian its 4 ohms for green and black, and 4 ohms for blue and red

@phaedrux When the motors are not connected and I want to move them no errors are displayed.The current for this motor is 1.7A.

M906 X1700 Y800 Z800 ; set motor currents (mA)

I try to start the engine with the command:

M564 S0H0 
G91
G1 H2 X100 

@alankilian I know this is just for a test rewired connectors.

@phaedrux

I bought this stepper motor. Still nothing is moving. Maybe all the motors should be connected. I have no idea what to do anymore. In my opinion the MB6HC is not sending, any signals to the motors. Multimeter shows no voltage, motors don't heat up, how to check if the board is damaged?

Maybe there is a simple gcode that checks the controllers and motors?

@phaedrux No, the motor was not connected in that photo. I removed one and the circuit currently looks like this. The motors use the same ribbons as the endstops. I thought the ribbon might be the problem which is why the cables are so shortened. I would like to not use the endstops but rather use sensor less homing so I did not connect them. Could this be the problem?

@dc42 I use the function < M564 S0H0 > and then <G1 H2 X100 >.
I shortened the cables - thought maybe there was something wrong with them.
I installed system version 3.2.2 because the default 3.3.3 was a beta.
The motor when connected to the lab power supply each coil jumps a step but when connected to MB6HC nothing happens, it doesn't move or lock.
By measuring the pins on the board it gets:
DRIVER_0_B1 is connected to DRIVER_0_B2
DRIVER_0_A1 is connected to DRIVER_0_A2

When the motor should be running I do not see any voltage on the outputs from the board. Should I select DC or AC on the multimeter? Is there any easy way to check if the controller is faulty?
What does <M122> diagnostics mean with "ok" controllers?

@phaedrux I did it right. I've searched the tutorials and I'm out of ideas what's wrong here.
