I made most of my parts from PETG and it’s been working so far. I have been messing with easel but haven’t cut anything from it yet. I can’t figure out how to do it in fusion 360. I think most people on here are using estlcam. It’s pretty cheap as far as cam stuff goes and you can use it for free if you don’t mind waiting 🙂
I would just focus on getting the machine made then worry about how to use it.
