Just wondering if the G0 speed can be faster then the max feed rate speed. On all CNC machines I have run (that use Fanuc, Mit, etc controls) the rapid speed was much faster then the max feed rate speed, like 2 or 3 times.
On a step/dir system it is probably not possible but on a servo machine that has high speed hardware encoder counters and possibly a velocity loop that is closed outside of the EMC position control loop it should be possible. It is just that during a G0 move the actually position may be 0.030" or 0.040" away from where EMC thinks it is, not good for machining but who cares during a rapid move. Andre' B.
