    Hi everyone,

    My first post in the 3d printer section! I have been working on a design using nema 23 motors, since I can find models that have very small step angles (0.45 degrees!).

    I have tried several ways of integrating these larger motors into a frame, and I have a design. I was hoping someone more experienced could take a look and see what they think.

    The problem is this:
    The idler wheel is slightly out of alignment with the motor pulley, due to the v slots not being at the same height as the motor shaft. I cannot think of a way to fix this.

    I've uploaded a photo, as well as a STEP file so you can take a look.
    Any ideas are welcome, thank you!
