A unfortunate plastic unclog attempt resulted in breaking off the CR-10 3D printers nozzle into two pieces, leading to damage of the Heater Block. While replacing the broken heater block with a newly ordered one, I made the mistake to desolder the cables coming from the sleeve into the GX16-8 aviation connector, without taking any pictures of the pinout, thinking I was going to find them on the Internet anyways.

Turns out, there are indeed no pictures of the GX16-8s Pinout. Another day and much confusion later, the pinout was successfully “reverse engineered” from the printers internal connections:


Here you go: The first (at least it seems) documentation of the Creality CR-10’s GX16-8 pinout on the Internet. Hopefully these pictures are saving you from the headaches and hassles I had, trying to find a proper pinout. You’re welcome.
