It routes the belts outside of the frame so less dust will reach them. Nema23 motors may have more torque than nema17.


Four F608 bearings are needed for each motor.

The small plastic rings will keep the bearings in place once the screws are tighten.

45mm or 50mm M5 screws are needed to secure the motors. Mine had through holes, so I secured them with a nut and a washer each.

what is the belt you are using, white one?

It is a HTD3M

Catalin suggested the use of F608 flanged bearings to better guide the belt. I think it is a great idea.

Now, I have updated the pictures with them.

Pulleys on the motor mounts. Nice re-use of existing holes and structures. Also removes downward pull on the motor bolts (something I don't like about some ext-belt arrangements, and why I designed my own ext mount for Nema17).

That is why I used a plastic frame holding it all together. After tighten it, it becomes quite rigid.
