Ender 4 - Power Main Plug & ON/OFF switch little box

thingiverse

The Creality Ender 4 connects directly to the 240V mains via a permanently connected cable on the 24 Vdc power supply. The ON / OFF switch on the motherboard box cuts power only to the motherboard. Connected to the mains, the 24 Vdc power supply is always live. I developed a small set that integrates a base including a plug in CE format, a 5x20 fuse, and a bipolar switch with integrated LED. This component costs 1.73 euros at Banggood. The window for integrating the plug/switch measures 47.50 mm x 27.70 mm. I planned a little gap so it mounts relatively easily but remains firmly in place. The first part fulfills several functions: catching the level of the mounting plate of the power supply, fixing the support box, and securing everything on the Aluminium 3D printer profile to the right of the 24Vdc power supply. The second part carries the plug/switch component and is fixed with two M4 screws on the columns of the first part. I tapped in M4 the holes of the columns whose printing Ø was expected for that purpose. Use a sharp tap, preferably new ones. For connections, I simply cut the original cable part while keeping the wire side/lugs connecting to the 24 Vdc power supply. I will soon define another system integrating at the bottom of the 24Vdc block but this "lower cost" solution already offers a general ON/OFF. I installed a 3A Fast blown type fuse for the 5x20 type. Currently, everything is operational on my printer!
