Ok well, 15mm isn't a common pitch size but they do exist. However still, things don't add up.?
The drives are set for 2000 micro-steps and your direct drive to the motors. 2000/15=133.333333 Steps Per mm.
If we work it backward just in case the drives dip switches are telling porky's then from the Mach3 Auto calibrate setting 125 steps per with 15mm pitch this would give a micro-step setting of 1875.? I've never seen drives that allow this setting and the manual doesn't show it either.?
So something isn't adding up here at all.
Regards the G0 y100 command then it will move to y100 coordinate position which doesn't mean it will necessarily move 100mm. If you Zero the DRO then it should move 100mm.
To move a set amount without worrying about the coordinate location then you need to switch to incremental mode, try this next time.
G91 G0 y100 and it will move the amount asked for from the current location. When finished type G90 to put back into absolute positioning mode.-use common sense, if you lack it, there is no software to help that.
