Homemade custom PCB guide using free KiCAD software

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. 0:00 Introduction 0:44 BIQU BX recap My BIQU BX video: https://www.youtube.com/watch?v=bfhhUVJkP_s 2:55 CHEP’s temperature switching fan circuit CHEP’s original video on this circuit: https://www.youtube.com/watch?v=NDXUHImA3Xc 3:43 Circuit simulation with Everycircuit app Everycircuit app for simulation: https://everycircuit.com/app 6:11 Schematic design in KiCAD KiCAD: https://www.kicad.org 9:07 PCB design in KiCAD 12:54 Toolpath creation in Carbide Create Carbide Create: https://carbide3d.com/carbidecreate/ 15:30 Cutting the PCB Genmitsu 3018 Pro CNC router video: https://www.youtube.com/watch?v=Y5nyjvytlBk 16:35 Post processing of PCB 17:16 PCB assembly and soldering 17:38 3D printing a mount for the PCB 18:51 Testing the finished circuit 19:34 Conclusion Buy quality and affordable filament from X3D.
