I am new to 3D printing and recently purchased a Ender 5 Pro. I came and the 8 bit 1.15 board was broken (couldn't run extruder). I upgraded to a 32 bit Creality 4.2.7 and also purchased a BLtouch 3.1 bed leveling probe.
I downloaded the stock firmware from Creality for the Ender 5 Pro and it seemed to work fine. I was having problems leveling the bed (it is high in the center) so that is why I bought the BLTouch. The 4.2.7 has a dedicated plug for the BLTouch, but, I cannot find any firmware to make it work properly. I, after a lot of head scratching, was able to get Marlin 2.0 edited with MS Visual Studio adding code for the BLTouch. Now when I try to home, the bed moves down, the probe moves to the back right position (like regular Z-Stop homing), then goes to the center of bed, the BLTouch cycles 2 times, but, the bed never comes up! It just stays where it is/was. The LCD says, "STOPPED" and then "Home Z". I seem to be the only one with a BLTouch 3.1 attached to a 4.2.7 board on the Ender 5 Pro. Any help appreciated.
