I think its unlikely to be the motor? Its possible to swap the drv8825 chips over, as you used headers. If it was a motor, simply swapping the noisy motor to the controller that is not noisy will pinpoint the issue right away. If the noise follows the motor - then thats a simple elimination. I have not experienced a bad stepper motor, I have always used the Stepper-On-Line motors and not once had an issue. But I have had numberous bad drv8825 driver chips, and there are quite a few of them in the...

Thanks for the reply and sorry for my late post Both rotator are the same. I attach a picture. I have bought another motor to try Regards,

For anyone trying to get myRotator working with N.I.N.A.: I was having trouble getting the rotator to lock into requested angles. To troubleshoot, I used Claude to write a simple sketch and ASCOM driver that commands the motor to take the shortest path to a requested angle, with no built-in wrap-around prevention. Here is what I found: N.I.N.A. appears to have its own internal wrap-around prevention and treats 0°/360° as a hard seam. Moving from 0° to 359° causes the rotator to travel all the way...

Make sure you are running the latest firmware What does the Windows app say? Motor Control Tab Is Coil power checked? If so 1, uncheck it and then click Set. Click the Settings menu Click Save settings to EEPROM Click Reboot the controller Exit the Windows App After the controller has rebooted, next Start Windows app Connect to the rotator Click the Motor Control tab Coilpower should be unchecked.
