Stepper motor problem Duet 3 MB6HC

kkallas

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.

@kkallas I really can’t see anything that would stop the motor moving. Seems like an SPI failure (@dc42)? When and where did you buy the board from?

@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

Have you tried configuring each driver and moving the motor for testing?

kkallas

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

Very strange. Please contact your vendor and initiate a warranty exchange. Include a link to this thread as authorization.
