Finally got all the 3D printed parts done, Stepper package arrived, and bought the complete kit. I chose to assemble the controller first. Here's a few photos. I have a DIY CNC router to help me. Worked great making cutouts in the cabinet. I chose to use panel mounted USB jacks. Makes a clean cabinet. Wiring is next.
Can you post the dimensions of the control box you used. Everything looks tidy and well spaced out.
