I mostly work with wood and plastic. I just used Precision Board (like Renshape: https://www.inventables.com/technologies/precision-board-plus) for the first time because I want to make a model with very good surface quality.
The model is 50mm high and I wanted to mill it all in one pass so I got a 1/4" long reach cutter, and it all (stock height + retracted cutter) just barely fit the Nomad.
I got extremely good surface finish on the horizontal surfaces, but very bad finish on almost all walls, see photos. Does the pattern hint at what parameters are off? Any feed/speed/cutter tips in general for Renshape-type material?
This is with Fusion 360 CAM, the outside is a contour and the inside cavity was with Fusion’s adaptive clearing strategy.
