I recently upgraded to a screw-drive setup, so my previous 9mm belt upgrade is available. Includes all necessary motor & idler pulleys, and 4 belts (one spare). My machine is 500 x 750, so 1 of the belts will need to be shortened. This uses zip-tie saddles to anchor the ends of the belts. The belts are genuine Gates Powergrip. This also includes a 15mm belt upgrade for the Z axis.
