I don’t think I really agree that delta style printers have a small footprint and about half of their height is not printing area.
“It is unusual for a delta style printer to have something else than a bowden drive because the motor needs to be fast enough to give people the extrusion speed they want, but light enough to let them get the x,y,z speed that they want without skipping steps.”
That is what I said earlier. Greg gets it. Having extra weight on the effector is trouble. That is why deltas use bowden tubes.
