I am trying to cut 12mm birch plywood for the milled/printed 3d printer, but I keep breaking bits. I have lost 2 Freud 75-100:
DW660 with variable speed controller, running at ~ 18k rpm. 2mm depth of pass with a 10mm/s feedrate. MPNC has been working great cutting MDF and pine. I re-surfaced spoil board and verified that the overall squareness of the machine.
Any suggestions on what could be going wrong?
