Thanks to tip from Reddit user u/FDL1, I looked into removing the USB cable from my Ender 3 3D printer. This is what I found and how I did it.

It was easier than I thought. One needs to have already upgraded to OctoPrint and have installed an aftermarket printer board.

​This "how to" will cover the MKS gen L. We'll be modifying the Raspberry Config file on the Raspberry PI, and we'll need three wires, about 6" long with female DuPont connectors on either end.

The 3D printing community has given away a tremendous amount of information and upgrades and just great stuff to further 3D printing. I'm happy to finally be able to participate for the hopeful betterment of us all.

I've never liked the stock cable sleeves, so I designed and made new ones from Taslan and #3YKK coil zippers. I used 36" (914mm) long zippers for this project, but one Ender only requires one 36" zipper and one 18" zipper. This is how to make them.
