Thanks for your comments Rob. The crossed rubber belts are a last ditch
attempt to remove the backlash from the joints. The use of friction pins
caused the joints to become so stiff that the platform would not follow the
action of the arms. I found that this project was very difficult to keep
rigid . It was also nearly impossible to program in a straight line and
maintain a constant depth for the cutter. Yes, it is processed cheese. Time
to return the parts to inventory and look for something else to try.
