General Mach Discussion / Choppy cuts in X-Y direction
« on: May 19, 2009, 10:08:38 AM »I've been dealing with this problem for a while now. Like over a year! I do mostly 3D contour cutting and have been getting really weird choppy cuts. I messed with lookahead and CV settings but never had any success.
I finally attributed it to gantry shake and slowly but surely started making needed improvements. None of my changes made a bit of difference. Including trying a more powerful computer.
I now have a more traditional piece I'm cutting.
I'm cutting a piece with 72 pockets laid out in a circle. The pockets that are at the 12:00, 3:00, 6:00 and 9:00 positions are smooth as silk. They gradually get choppier until they hit the 45 degree mark and then start improving. There is a noticeable amount of chop on the first pocket that requires X+Y combined movement.
I'm dying ova here!
