Good update to you project. Are you sure the noise isn't being amplified by the hard surface of the desk it is sitting on? On a softer surface it may naturally quieten down a bit.

Kind regards.

Dubbie,

The 3D prints look very nice. Did you achieve a tight press fit of the stepper motor into the base? Seems like it would not be to difficult to include mountings on either side of the housing to allow the stepper motor to be screwed into the housing. Just a thought.

You might be able to address the vibrations/noise by microstepping the motor, if the driver and the nano can support that. On the topic of limit switches, there are many way to handle this. A simple method might be to use an optosensor and a small flag on the angle bracket (more reliable that limit switches?).

Good luck on your continued development!
