Hi, I am confused by an odd stepper problem which I can't understand. The stepper affected is the one driving my rotary axis and the problem is that it won't go fast enough... To explain - if I issue a G1 command in MDI, I am limited to a F20 speed as, beyond that, the stepper gets very jittery and loses steps (at F40 it gives up altogether). However, if I issue a G0 command, the stepper whirls away happily at 3 or 4 times the speed and doesn't seem to lose steps at all (i.e. I can send it one way and then the other and it returns to where it started.). So, what is the difference between a G1 command and a G0 command and how can I get the G1 speed to increase reliably up to almost the G0 speed? I'm running the latest version of EMC2 on Ubuntu (unless I've missed a service release in the last 2 weeks ). -- Best wishes,
