Why won't the claw move left to right, everything else works.

@gambit2115 I suggest that you take a look at the stepper motor on top of the claw itself. Check this guide El reemplazo de la garra de The Claw and remove the cover from the mechanism the drives the sled. Take a good look at the wiring and with a multimeter see if the motor gets power when you move the controller. If it does you pretty much know it could be the motor. If it does not you will have to check the circuit board and the controller. Use this guide Reemplazo de la placa de circuito de The Claw for that. Check the limit switches on wither side of the gantry as well to make sure that those are working and not stuck in the off position. Do not forget to post plenty of pictures on what you see with your QUESTION. That way we see what you see and can follow you along your repair and guide you further if possible.
