Machine file generated from Artcam 2018, 1/4" 90deg sharp engraving bit, 17k rpm, 70ipm. Letters about 3/4" high and from standard Times New Roman font. Set for constant velocity. Ragged edge on areas of the letters is consistent and repeatable. Got any input for me to smooth the edges? Of course I'm supposed to deliver tomorrow.http://www.talkshopbot.com/forum/att...id=32055&stc=1
