- Print out object at a high infill (i used 60%)
- Ensure hole sizes are correct, drilling any holes if required
- Check that a M4 Bolt fits correctly in the slot
- Tape the any surfaces in contact with motor sliding with kapton tape to reduce friction
- Once ensuring that the part does fit, drill a 4mm hole where the Tensoner bolt meets the wall
- Screw motor in, just tight enough that it still moves by hand
- Use the tensoner bolt to tension the belt. Remember that the tigher it the belt the the more the stepper motor needs to work.
