About a year ago I decided to retire my Camtronics CNC driver and upgrade using a CNC4PC breakout board. I replaced the mechanical home and limits switches with optical units. About week ago I found out I had left out a wire connecting ground and a Gecko and now it seems to work OK. The motors run smoothly on all axis when using Jog is used but when I tried the Mach3 self calibration and it produced very large numbers which would not work. G0 Z 1.0 registered 1. on the mach3 screen,but the actual movement was .0588". A similar error was true on the other two axis. I have read and reread Mach3 Mill install and configuration guide and looking .where to look next. I am looking for suggestions.
