View Full Version : GRBL jitters

01-07-2014, 12:00 AM

I have been using my cnc router for about 2 months now. It is running grbl with nema 23 and dm542a stepper drivers on an arduino uno. I just started to use g1 code to approximate complex shapes, but this has started to cause me problems. The machine gets jittery a little while into the g1 approximations 2-5 sec into. It then starts to just run small groups of code then stops for .2-.5 sec then runs the next. It is almost like it can't process the g1 code fast enough. I must be doing something wrong, any help would be much appreciated!
