General Mach Discussion / Re: Inverse time feed bug?
« on: January 05, 2009, 09:59:42 PM »
Thanks for the bug reporting advice. I got an answer back already! G93 only works for XYZ moves, adding ABC is on their to do list.
I modified my g-code generating program to produce synthetic feedrates for A axis moves in G94 mode. Seeing feed rates of F2000 in the g-code for a mill that moves at 20ipm (at best) looks very strange, but a test run on a piece of scrap works reasonably well. This solution isn't perfect because the g-code has no control over whether Mach will choose a blended feedrate based on the rotation diameter setting, but I can cut my parts.
