There are lots of designs for making a circuit board drill press for PCB fabrication. I thought I would try one. Read more
Making a loop controller PCB is pretty straightforward.
My 3D printer now does auto-leveling using a proximity sensor and an external control board. This DIY PCB article describes completion of printed circuit board used in this project.
