I know what you mean - Fusion 360 is not the most intuitive and user friendly piece of software I know… Still, the toolpathes of it are good, and it can very well do multi-pass setups, which saves a hell of time as compared to Luban’s simplistic approach. I would not be surprised if even some of the bugs I found with the 4-axis-milling of Luban would present themselves in 3-axis milling.
I am currently looking a bit into DeskProto - they give you a 30 days trial, and with 250 bucks for a hobbyist license, it is somewhat affordable. They offer far less milling strategies and has much less features as compared to Fusion, but it is much simpler to use, and for me also much more intuitive. They have a post processor for Snapmaker.
Oh, believe me: You can run into stupid situations regardless of which CAM-Software you use! The Stop button (or a quickly accessible mains switch) has saved me already a few times, and I hardly ever use Luban…
