Ender 3 Pro Print Nozzle will not Auto Home after mainboard v4.2.7 & BL Touch install
On my ender 3 pro, after installing mainboard v4.2.7 & BL Touch with Ender3-v4.2.7-BLTouch-20210306.bin firmware from Marlin bugfix-2.0.x , the nozzle head does not auto home properly.
Might anyone know what could be the issue?
Here's a video of the printer attempting to auto home :
Note : disregard the unhooked cable under the printer bed in the video. It is totally disconnected and left over from the BL Touch install. Removing now... 🙂
Solved : had the black and white wires on the BL Touch reversed.
