How does the new motor compare to the old motor - specs?
Thanks a lot, I could make it work. I checked the cabling and the belt alignment.First thing I would be trying would be to remove the motor and leave it connected electrically. Then try a brief run while checking the motor rotation etc. This should verify whether the stepper driver, interconnect cabling and motor are capable of running. Then try to drive the system that the motor should operate by hand, checking for grabbing, friction etc.
I'm suspecting that the issue is either mechanical binding or component/system failure in the controller, power supply, cabling etc. If it is electrical, you can also swap motor connections at the controller so you have a short run with the controller driving a known good motor, and a known good controller driving a motor that you are not sure off. That helps isolate the issue more, to PSU and controller or cable and motor. Keep swapping like this until you can isolate where the issue actually is, then you can rectify or replace that section.
