View Full Version : Lines in mold

12-27-2007, 02:50 PM
I'm making a mold out of plastic flat stock.While rastering both horizonal and vertical I get lines in the mold.They are not deep and about 1/4" apart on horizonal and 1" apart on vertical.I adjusted for backlash and it did get better in the beginning,but the more it mills the worst it gets.My mold is 2.5 x 5.375 in.It starts about half way across the mould.I don't think it's the z axis,but I could be wrong.Just need some help on this one.Thanks!

Depends on your CAM intol/outtol setting, sometimes raster cut at 0 and/or 90 deg will cause those lines, try raster at 45 and/or 135 deg.
