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.

Beautiful! I saw that page on parallemic as well... Looks like you did a
good job making the lego version! I liked the multiple worm gear setup you
used to take up the backlash. Just a couple of questions... What are the
crossed rubber bands for? Do they help to take up the slack in the joints?
Also, what are you cutting??? Is that processed cheese??? As always, very
impressive.
