Re: For nema23 motor

There seems to be two versions of the 1/4 inch bore pulley on the MakerSlide store, one with 18 teeth and one with 20 teeth. Is there any reason to choose one over the other? I know the NEMA 17 pulley has 18 teeth, but does the larger 20 tooth version change anything anywhere? Yes. Since the tooth ...

Re: For nema23 motor

Dual Drive Setup (Dual Motor)

On the old Forum Edward was discussing his dual drive set up, driving two motors from the same driver. On this forum, the drive shaft concept has survived, but not the dual motor one.
