Makerfarm & Z motor coupling

[old man emu]

Doc,
Get the ones Roxy showed. They have a grub screw to tighten onto the stepper motor shaft and another to tighten onto the threaded rod. Then there are another two screws with close the slit for further tightening of the coupling.

You can alter the position of the coupler up and down. I have mine so that the lowest grub screw is at the edge of the hole in the frame and the Allen key can just fit in the top of the grub screw.

If worst comes to worst, I have heard of some people cutting away the skirt on the X axis carrier. (So hard to explain without pictures.)
