Hi everybody,
I hope you guys can help me with this one. I build the hobbycnc board and hooked up my 3 80oz-in steppers. I ran a test with TurboCNC and noticed that when I jog the z-axis slowly the motor just "wobbles" (takes 2 steps CW, 1 CCW). On high speed jog it turns OK but has no torque (I can stall it by just laying a finger on the axis). The X and Y-axis both function normally. I tried swapping motors (X to Z, Z to X) but this has no effect. I'm at a loss.
Any suggestions?
Thnx,
