I am trying to do something... Special (lemmy.world)

So someday ago I tried to fit in the "Back Mounted Electronic Box By Teaching Tech" On my Ender3 (OG). Only problems..... 1st: The box would not fit (The tolerances on my printer are awful) so I spent 2hrs sanding down the box. 2nd: The printer would not turn on, it took me a day to realize that I wired the cooling fan BACKWARDS.

My objective in this Project is to gain Cable Management on my printer (Which is now far worse than before btw, will try to fix) and I am running Klipper on a [RASPBERRY PI 3B+] (do you see where I am going?)

So I try to reduce the amount of unnecessary cables AND I WAS WONDERING (Since I saw the fact on a Teaching Tech video) if I could connect the raspberry pi power directly From the motherboard (SKR MINI E3 V2.0) to the PI's gpio to power it.

So my question is:

On what ports should I connect the two (+5V and GND) cables ON THE MOTHERBOARD and THE PI'S GPIO.

If you did not understand something feel free to ask me.

I just used a buck converter and a USB pigtail for mine so it still plugs into the pi where the power cable used to it's just running off the Ender 3s power supply. They were fairly cheap on Amazon something like $6 for a pack

The only cables you really see for my printer are the short USB connecting the Pi to the SKR on the back, and the power supply cable. The rest is hidden or inside cable chains.

Definitely made moving the printer easier and much less of an eyesore of wiring.
