Hi Everyone,

I have some setup questions....as a total noob....

I've got the Rev3 G540 and the latest stable Mach 3 installed. I used the XML file supplied.

When I hit Page up/down nothing happens even though I have a stepper plugged into the ZAxis port on the unit. If I hit right or left arrow the stepper moves but it moves in only one direction no matter the key hit.

No other axis will take any commands.....

There are no faults on the G540 or in Mach 3.

Could there be a problem with my Parallel cable? I double checked the motor pins for step and direction and they are as stated in the G540 manual.

Any help would be great!
