So here is the problem. My y axis just moves in one direction. If I reverse the direction in Mach 3 nothing happens. I read that I need to set the drive to low settings in Mach3 which I did. And the motor on the y axis moved in the correct directions. However today the y axis is again just moving in one direction. I tried setting the axis in reverse in Mach 3, but know joy. I reset the drive the high, no joy, reset to low no joy. When the machine does move, and this was a test air run, it just moves in a sort of zig zag movement and draws what looks like the top of a castle wall. Anyone have any ideas. Thanks
