Oh bum, looks like i've gone and run into another minefield
I think I need 2.5D, I'm ok with basic 2D and can generate 3D .stl files with an app called OpenScad which i use for the 3D printer. In reality I'm probably not too far off in terms of stuff in the brain, it just feels like I've been taken from the paddling pool and thrown into the olympic pool but I've still got my armbands on
3D printing is pretty easy by comparison, it only has one tool - a fixed diameter nozzle, fixed layer height and once you get it to work, it works fine. No offsets etc - its additive so all jobs start in the centre of the bed - no workpiece
I guess building a multi-purpose machine means I have multiple headaches now - carving, routing, milling, etc
