Hi all.

My newly built CNC milling machine is now moving in Mach 3. I have encountered a problem i am not sure how to deal with. I have 3 Stepper motors, each with it's own Leadshine M542 controller, i can move all my Axis + and - but the movement is not accurate, if i move say X axis 20mm + using the DRO readout in Mach3, i get say 33mm actual movement on the machine!!

I understand it may be the Dip switch positions on the M542 Drivers, can anyone advise pleased as of correct positions, or know were i can get relevant paperwork.
