Tell us about yourself!
I didn't have the hex nuts, was almost ready to use double-sided exterior tape as a temporary solution, then stumbled upon someone else's hint, which fit my own need. Appreciate your guide and its pictures. I will go on with the flipping of the wires for the SKR mini e3. If I get stuck or find something else to share, I will come back. Again, thanks.
Insert the screws from the bottom to follow the thread.
Just a hint, the probe kept falling because those screws are meant to be inserted from the other side to follow the thread. This is by Creality's intended design and instructions. Once you do that, you will not need the hexagonal nuts.
