Title: updated Mach 4 and the Hicon plug in, stuttering, Jerky
Post by: lgr on November 10, 2025, 08:07:45 PM

After updating Mach 4 and the Hicon 7866 plug in the the machine has had a stutter/jerky motion. I cloned the profile and reduced the accell and decell numbers by 50, it's better but it still isn't as smooth as it was. Any suggestions?

should have read 50% not 50, motion mode constant velocity, distance mode absolute
