Motion Control drivers and motors

[bruce_miranda]

So I've finally got my motors running smoothly on the Mach 3 but I've hit yet another problem.

Every so often the motors will stall for no apparent reason. I first thought the lead screws where getting jammed but I've even tried the motors without any load and they still stall.

When the motors stall even if I try to help it to move forward it won't. But the moment I release the jog key and start jogging again it works fine.

Jog at slower speeds causes it to stall less but it does stall. Also when jogging at slow speeds I can hear the motor sometimes hesitate.

See the video or a fast and slow jogging X axis without it being connected.



P.S> I don't know what's the BBCode to embed YouTube Videos in this forum.
