    Mach 3 feed rate problems

    Hey all, my taig cnc mill is running very good now, but the problem is that mach 3 doesn't comprehend the feed rate I set in MADCam. It seems that no matter if I set the feed rate to 20ipm or 120ipm, it doesn't seem to change the speed of the machine very much, if at all. And if I try to speed it up with the FRO, it will speed it up, but it will then have glitches and ruin my part. The only thing I can think of is a glitch in the program, because it has happend with two different computers.

    i'll try and get some g codes up here, but it is happening with any g code i make, even if i manually edit the speed in the code, so that leads me to beleive that its mach not madcam. but i'll try and get one up.
