I have a Kelig cnc system on a DIY router table. The X axis seems to be working fine but the Y axis direction is unpredictable. Sometimes it moves in the correct direction, stops and reverses itself. Sometimes goes in the same direction regardless of which jog button I press.

This is a DIY project running a trial version of Mach3, on an old laptop... Just trying to get things working before I invest more money.

Any ideas,, why would the motor change directions?

Thanks. Swampbud1
