Hey y'all! I'm finding that I'm getting pretty poor chip clearance when running profile paths that are more than 1x DOC that are essentially slots. For example cutting out the body shape of a guitar from a big square wood blank. Even with upcut bits (1/4" going 1.5IPM, 12k, .17" DOC). The first path seems to work fine, but then subsequent passes leave more and more until I see things like:
- bit deflecting and gauging the edge
- lost steps from the bit binding
- bad noise from the bit
The machine is obviously struggling and therefore I have to stop and until I figure this out I'll have to not do these operations.
Thoughts? Should I slow the feed each step down? Should I do two profiles making a wider slot each pass? (Both of those require a lot more paths and programming...) Am I just going too fast overall for slots up to 1" deep after all the passes are finished?
