At work we have a paint agitator that is belt driven. The belts are constantly stretching and need tightening and adjustment. Some replacements we have looked into are gear driven (like a bike) with a solid chain that will not go slack or break once put in place. Has anyone considered attempting a gear/chain driven set up for their x/y motors instead of the seemingly common belt driven set up? Just curious if anyone has seen it attempted or considered giving it a go?
