Good afternoon Tweakie. Last night I uninstalled Mach 3 and reinstalled it. Loaded a G code file that I used before with no problems The project shows up in the display screen so small you cant hardly see it. I run the axes test for X & Y entered 24.5 and it moved 1". When I run the file the router does not hardly move and I'm running in inches. Rechecked my settings and everything set to the settings for my router. Don't know what to do now. This unit was working great at one time before the cat walked across the key board. Took the computer to repair shop and they said everything was fine.
