WOW!!! I've got the same issue with HDPE now but only using a 2mm cutter. It is melting a few mm above the tip of rage end mill, setting hard and then scratching the work piece! I keep setting shallower depth of cut... So you think I should go the opposite. Regarding cutter spindle speed, what should that be?
