for foam cutting | | Hey There,
I am also cutting large amounts of foam with aa cnc machine. I have had your problem before many times. Mine was resolved in two ways. First, I got a drill bit that was specifically designed to cut foam. It was hard to find for me but i found from a company name ONSRUD. If you know of any other let me know. Also another big issue was my cutting speed and travel speed. It took me long time to adjust that. Comes with experimenting. Also, if you look at what you are cutting, if the drill bit is not designed for foam then you will have a perfect smooth going in one direction, and you will get the rough edge when the drill bit is coming back.
I hope this helps
