Could someone help my figure out the appropriate parts needed to switch from my current belt drive system to a threaded rod system? See attached photos. It seems that there is slack in the belt drive system. I've tightened multiple times, but think that it is just time to upgrade. I'd like to reuse the stepper motors (MT-2303HS280AW-OB). My goal is to be able to cut 3/4" baltic birch in one pass. Do you think this motors are beefy enough. I'll provide an appropriate router.
