Taking the chance: As a hobbyist with a decent CNC with no intent of using it for commercial work: Linux "support" was driving me from Fusion to Onshape. CAM is driving me back to Fusion.
Please consider pushing the idea of having CAM for the hobbyist level in Onshape in your company, I know there's not much in revenue us hobbyists, but I'd gladly pay up to 20-50 per month for such a license. At least that's more money than 0 :).
I'm sorry, as far as I know the leadership is pretty clear on that. For a foreseeable future CAM will remain a Pro only feature.
