y motor drive

the first idler pulley induces an uneven motion in the

timing belt as the teeth pass over the bearing.

need to replace it with a 10 tooth T5 pulley.

8T drive gear

y motor mount and new y bar clamps

mdf y bar clamps replaced with polyester resin

fine adjustment allows free movement for 4 linear bearings
