Hello,

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.
