Hello,
I have got the following problem:
The extruder motor doesn't work. I tried the motor with cable on the output of the y-axis and it worked. I changed stepper driver with a driver of another output and the stepper is okay, too. Every other motor works. Yesterday everything was okay, then I changed the power supply and now I have got this problem..
Does anyone know this issue or can help?
Thanks for help.

Hi

Sometimes it happens that some connector does not contact properly.
It may also happen that the cable slides out of the plug.
When you connect everything the second time, it works.
That is why it is always necessary to do it precisely and accurately.
And it is always worth checking at least visually the quality of the connection.

1.You need to check the wiring
2.Check the solder joints of the PCB backplane

Did you heat up your nozzle? Otherwise it won't turn.. (at least in all my Marlin configurations, I don't know yours).
