Getting flats on my circular pocketing. All sizes of circle affected, more or less on the north quadrant as viewed from operator position. Running Mach3 on Seig X3.
Seems like a software/setting problem? I seem to remember this coming up before. But can`t recall where.
Any leads appreciated.
Got ballscrews fitted ?
Flats on circles are normally mechanical, slack in nuts etc.
You can compensate in mach under Backlash compensation but it's a cludge.
For one it doesn't work correctly and secondly if there is free play, even compensated for, the cutter can grab and pull the work.

Check your software for overlap values or lead in lead out and also cutter comp activation points
Yup Jazz is right, that viagria isn't all it's cracked up to be.
Gave mine to me grandad, stops him rolling out of bed at night
Ah right! - To get good circles. You need to securely tighten the main casting to Y axis ball screw journal.
My "nuts" are now secure in a steel thong, but now have the problem of walking a bit odd!
Apologies to have wasted any ones time.
My father-in-law had Viagra to stop him pissing on his slippers.
