CV Turned on with a 0.01mm distance tolerances seem to be the answer if you looking for faster engraving and sacrificing as little as possible accuracy. I also read that a "smooth stepper" might help?
I've been reading as much as I can since I joined , I did read that one person say that a weak servo motor might also be the cuz for the jaggedness when engraving a arc at high speed, any truth in that? We have a Delta b series .75kw ac servo drives [comes with encoders fitted] or possibly that "his" machine was to flimsy, our machine is 1.2tons so it's not flimsy i think..
