Playing with #OpenScad and some inverse kinematics math… maybe one day I’ll make this SCARA laser cutter bot in the real world.
I have selected some thrust bearings, still have to settle on how to transfer movement from steppers to the arms and which screws/bolts/nuts use to hold it all together. The tip of the two arms is the most puzzling bit to sort out.
Anyway I have made a parametric design so I can fiddle with plastic thickness, bearing dimensions, element cuttings etc.
