Does anyone know how to change the 2gt closed belt loop? Mine just broke and I cant figure out how to change it… Thank you for your help!
Loosen the set screw on the pulley for the Acme threaded rod (or the other one if that is what you have) or the pulley on the motor if your motor’s pulley is not pressed on. You only need to loosen it on one pulley. Then, remove that pulley. You should then be able to put the belt on and get the pulley back onto whichever item you took it off of. If you can’t, you may have to loosen the stepper motor mounting bolts, install the belt and pulley, retighten the belt by sliding the stepper motor back to the original position, and tighten the mounting bolts. Once you have everything in place, tighten the set screw.

Should be able to do it by loosening or removing the stepper motor screws. Find the original assembly instructions and that should help.
