Re: Steppers stall/oscillate at low feed rate. High feed is OK.
You are experiencing resonance in the stepper motor. This is normal and occurs at low speeds as you are observing.
To solve this you could use a stepper driver with an anti-resonance function built in such as the Geckodrive stepper motor controllers. If you’re current stepper driver hah anti-resonance, then it may need to be adjusted.
Another solution is to use a resonance damper on the back shaft of the motor. If you do a search you should be able to find a lot of information on the damper me.
