I'm still fumbling with my design for a CNC delta machine. I plan to keep it very small, with a 90mm x 90mm x 50mm cutting area. I may try threaded rod with an adjacent linear smooth rod for each tower.
I'm having difficulty finding any inexpensive joints. Nice metal one can be $20 a piece. I assume a cutter would simply be too much for magnets and balls.
Another thought I had was to fix the cutter at the top of the machine, and use a design similar to the quantum Delta (basically the bed moves and the head is in one place).
I love all the other designs, but I seem to have gathered a screw driven delta would have the best chance at rigidity.
