Finally got this thing put together and working and milling. So happy about that. I’m using Fusion 360 with Universal GCodeSender to control it. However I’m having some issues with the Cam feature and not being able to get both my tool paths to work properly also my contour tool path clears out my tabs of my 2d contour path. Anyway I’ve attached the file if someone is interested in taking a look and trying to figure out what I’m doing wrong.
I am by no means an expert, but here’s what I did, which seemed to work:
I switched the order of the operations so that the outside contour was carved first, and then I turned on ‘Rest Machining’ in the other contour operation, so that it would stay away from areas that were already machined. This causes it to only cut the inside contours, and leave the outside contour and its tabs alone. See screenshot for results.
I know there’s also a way to choose areas an operation should stay away from, which would allow you to do the same thing without changing the order, but I’ve never tried that before.
