NEMA 17 stepper mount for GSO Linear Bearing Crayford. Tested on a Newtonian, your results may vary.
Tested on a Newtonian, your results may vary. The GSO Newtonian Crayford that Agena Astro carries have a curved shaft support that make the design a little more challenging. This mount and adapter follow that curve and should snap in place. You will need to replace the M3 screws with screws that are slightly longer. The stepper mount itself is held to the adapter by M3 screws. The adapter is designed to use M3 threaded inserts for the stepper mount retention at the front of the adapter. I'm using a 100mm 2GT belt but it is quite tight. A 110mm belt would be better.
