I've noticed a very jagged nasty wall finish on my black acrylic parts. The Acrylic was purchased from Amazon awhile back and can't remember it's specs. I'm running an Epilog 40w 24mini, @ 12 speed - 100 power - Frequency 5000 as suggested in the manual. I just found out that Cast acrylic engraves better then it cuts and the complete opposite with extruded acrylic. Are there any tricks, speed & feeds, etc.. that might help the wall finish look better besides sanding it or maybe this is a stepper/servo tuning issue ?
