Since I am getting no replies about my previous thread I will post a new one. Does anyone know if MADCAM/Mach3 4 axis postprocessor support G93 (inverse time) generation of G code? This appears not to be present in the "stock" mach3 4 axis postprocessor in MADCAM. The problem is that I need to have separate feed rates for X,Y,Z and A axes else the A axis runs at very low feedrate. Mach3 and Mach4 programs can accept G93 but if the postprocessor does not calculate F (feedrate) at every line with a G01 command the feedrate needs to be entered manually, clearly impossible. So the G93 federate needs to be calculated and inserted into the Gcode by the post processor.

Somehow I seem to be asking impossible questions...

OK, I was able to write a PP for MADCAM, using the help section, that creates good Gcode using G93 that Mach3/4 can use. Apparently everyone knew this already...
