Been doing some more testing cutting air I have a Gcode that has small arcs and lines (high speed toolpath) making 2 slots that are .280" wide with a .25" end mill. Ran this same program at work on a "industrial" machine with no problems, actually looks like table is vibrating its so fast
When running gcode on my mill, speed of axis look good at start, then after a few seconds axes start slowing down. Then if i pause program and resume, speed of axes again looks good at start and then slows down. I tried increasing the look ahead time. This helps a little but what ever look ahead i have, axes will wait that long after i start gcode before executing gcode. And still slows down after a few seconds.
Attached is gcode. Any ideas?
