setup right for the machine. I'm using 1/4-20 all-thread for the
leadscrews and have astrosyn NEMA 23 motors that I think are 1.8
degrees per step. I setup the axis for 200 revolutions per step and
20 as the tpi which gave me an increment of .00025 inches/step. When
I jog the machine say 1.0 unit I was thinking it would go 1" but it
doesn't. It is more like .25" Am I calculating wrong or are the jog
units not in in inches? I've set the units to inches in turbo cnc.
