4.2.7 Upgrade with BLTouch Z axis down problem
Today I upgraded my Ender 3 Pro with a 4.2.7 motherboard and BL Touch. I downloaded the .bin from the creality site and since I used the new board, I installed without the adapter and used the firmware "4.2.7 Ender-3 pro 32bit Marlin2.0.1 BLtouch V1.1.2without adapter board TMC2225.rar"
On the motherboard, I unplugged the z-axis plug and stuck in the red plug from the BL touch as instructed. I also made sure the pins were properly plugged in to the main plug from on the new board.
I un"rar"ed it and got the .bin on a micro SD card, inserted it and turned the printer on.
All seemed fine with the BL touch going in and out but when I went to auto home I am noticing that the Z axis will no longer move down. When I go to adjust it, it goes only up.
Has anyone seen this and if so, how did you fix it? Thanks! Please do not post the Teaching Tech video, I have seen it multiple times and being that so many steps were missing, it is extremely frustrating to try and follow
