A few quick thoughts
I thought there was a way to use F360 as a CAM then export?
In both Fusion 360 and EstlCAM, you export g-code. You will need a post processor to export from Fusion 360. Don has one based on the earlier guffy one, but it is still beta. The guffy one has been around a long time, but due to recent changes in the Personal version of Fusion 360, you will need to limit the Z feedrate to make it work properly. EstlCAM is the easier pathway for starting out.
I have a box of material for this plate
I’d practice with cheap stuff to start. A 4’ x 8’ x 1" foam will run about $17. A 4’ x 8’ x 5mm underlayment will run about $13. Lots of material to work things out before cutting something expensive.
(terrible to get into the hobby side now with them pushing the full version on you
The Fusion 360 just released the final changes it listed back in August for its changes to the Fusion 360 for Personal Use license. I find it still very usable for my projects. I do miss a couple of things though.
