I have some small 15mm steppers, similar to this.
https://www.aliexpress.com/item/32872829855.html I am trying to drive them with an A4988 stepper driver. I can run them at full step and half step, but anything smaller and they don't move linearly - one phase appears to step correctly, but the other appears to stick, then jump after a few steps. I've tried adjusting the current, but it didn't make any difference. Is there anything special about driving these motors?
