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.

check the config/port and pons/motor outputs
to see if your dir and step pins are enabled and correctly configured?
check if by mistake you press the online/offline button?

Thanks for the reply. I had checked all those items but had an epiphany and went back to basics. There it was: the port number had SOMEHOW, and strangely been set to non-hex characters from the expected 0x378. I have no idea how it happened, since there was no reason for me to change it. Anyway, I set it to 378 and all worked again. My laptop did go wonky later on and I had to reboot it.
