Might be a side note here, but could you look into supporting Servo motors as well (and maybe call it the “Duet 4 CNC”). I think there’s a good market capacity there in sales if you have a better integrated CNC solution than something like SmoothStepper. It would mean taking on more development scope, but I know it’s been a growing segment within the existing duet board users. As E3D and others are perusing, it’s looking like a hybrid CNC-Mill and 3D printer combos are the ‘next big thing’ in the 3D printing world.
Anyway, just a thought. The closed loop capability seems like it’s 70% of the way there anyway.
