Hello, I am an inexperienced cnc woodworker and need some help from you guys. The problem I am experiencing is having the bit drag on the wood and make the cut offset. I use an evolution 4 bobs cnc machine. I am only going down .03 inches into the wood at 70 inches per minute. Before the bit fails and gets offset it is running correctly and without issue. Please give me some recommendations and keep it vague (dumb it down) for I do not know these things.
