So, is it too late to solder the wires to the bed? If its not I can send you some nickle silver solder in which to do it.
Whew, 50 collators printed the right way.... that's a boat load of hours.
I would just like to purchase a 3D printer to maybe print up several more collators for myself to use. I'm thinking about a center shaft with bearing and slot and running it with a belt drive motor probably a small sewing machine belt of some type with a torque arm that when it moves too far due to a malfunction it shuts down.
