So you still move the stylus like I do on a part sitting still?
I want to built a traces for my Nova lathe with a rounder and long straight bit. I had a Craftsman tracer with a scraping bit and it created more work that is did because it tore up the surface. a high speed router will make a clean cut but it take a pretty massive frame and It is still in the drawing stage -planned with an aluminum frame rather than wood like I see some made.................Cheers, Jim
