Stepper motor is sluggish.
Posted: Tue Nov 11, 2025
Hello everyone, I have a question I'd like to ask.
My drilling program is having a problem with movement in the X-axis direction. It stops before executing the third line of code, makes a whirring sound, and loses position.
The motor is a NEMA 42 (https://www.oyostepper.com/category-10- ... Motor.html), and the motor output settings are exactly the same. Mach 3D's screen shows the program moving normally, and the code is correct. When I uncheck the backlash compensation option, the program runs normally.
However, at this time, the contour program cannot machine the part correctly. I have checked the milling machine and found no mechanical faults.
Any help and thanks would be greatly appreciated.
