Hey I have some trouble with making deeper cuts or pockets in hard wood. It always fails. I wanted to cut a small box. I did 2 mm depth per layer and 6 mm/s feed speed. So far everything was fine. But always on one of the lower layer it fails. The CNC goes crazy and destroy everything.
My guessing is, because of small vibrations the toolhead hits at one time the material with his howl cutting edge. Am I right ? Do you have experience with deep cuts ? Is there a solution? Maybe special toolhead’s?
