The BIQU BX needed two things to let it sit idle with Octoprint running: a screen saver and quiet fans. In this video, I manufacture a custom PCB to implement a quiet fan switch circuit by Chuck from Filament Friday.

The guide uses a cheap CNC router and free software. My methods are a little unconventional at times but the end result is just what I wanted.

Thanks to CHEP for allowing me to feature his most effective circuit design. It has made a great difference to the way I can use this printer.
