General Mach Discussion / Re: Mach 3 Upgrade issue - for a frustrated Aussie

Lance,
All the VFD's I have used have had separate inputs for CW and CCW rotation and these are connected to separate output pins from Mach, one mapped to M3 and one to M4. This then lets the GCode specify CW or CCW operation with the M3/M4 commands.
Tweakie.
