All code. Any code. From the Roadrunner to simple one line "g0 x0 y0" or "g1 x10 y10". I am NOT having this problem just with one file. I have this problem on all g-code files.
As I said in post 12, I can go to the MDI screen and enter "g0 x10 y10" and it stops at consistent intervals. It doesn't matter what g-code I use.
It makes me suspect something about the difference between the way Mach3 generates pulses from g-code as opposed to generating pulses for a jog command or in the motor tuning mode. Unfortunately, I don't know enough about how Mach3 does what it does to be able to speculate why it jogs smoothly but executes g-code with these stops.
Does that suggest anything to you?
Thanks,
