jumpy rapid traverse
Posted: Thu Sep 17, 2015 3:55 pm
Hi Everyone,
I'm having an issue with a 4th axis parallel finishing toolpath. The rapid traverse above the part is broken into several sections of g-code, all of them straight moves along the Y-axis. This is very hard on the machine, causing jittery starts and stops. Here is a sample:
Z1.3549 B-6.000 F150.
G00 Y23.4800 B-6.600
Y20.8600 B-7.200
Y18.2400 B-7.800
Y15.6200 B-8.400
Y13.0000 B-9.000
Y10.3800 B-9.600
Y7.7600 B-10.200
Y5.1400 B-10.800
Y2.5200 B-11.400
Y-0.1000 B-12.000
G01 Z0.9000 B-12.000 F150.
Y26.1000 B-12.000 F125.
The cutting depth is Z0.9, on the second to last line. Above it is the rapid transfer. For some reason it is broken up into a series of Y/B moves, 0.6 degrees at a time. I don't see anything in the post processor settings that is relevant, and nothing in the options for the parallel finishing path.
Any thoughts?
