I was calibrating my CNC (Xylotech motors) and pretty well got that perfect, using a dial gauge for measurement. All my jogging by keyboard or G0 commands worked without issue. Then I decided I wanted to change units from inches (what I used for calibration) to mm, DESPITE the warning not to do so, because I was having problems with a program using metric units. I finally found out that G20 and G21 are the commands I should be using, but when I went back to running the program or checking the jogging, my motors did not work. I tried to undo anything I thought was the problem, to no avail. Then I complicated matters by downloading the latest version of Mach3. I had Version 3.00 originally. This didn't help.
NOW, when I jog, the DRO increment or decrement as they should but the motors do not move whatsoever. When I try to zero any axis, once again the DRO's inc or dec VERY slowly but nothing physical moves.
Any ideas? I tried rebooting, running the old mach3 and went over pretty well all the settings to see where I screwed up.
