In my ender 3 pro V1 i installed a motherboard 4.2.7. Before everything worked just fine on a 1.1.4 motherboard.
I have a BLTouch installed on the 27-pin board, and wish to continue use the BLTouch via the Z-sensor-pin.
I installed several firmwares, incl.Marlin2 with necessary changes, but on none of those firmwares, the steppermotors were moving. Everything else works just fine, except the motors... THe only thing they do is give a little jerk once, and that's it....
So my Ender 3 pro only has a functioning LCD, and heating.... HELP!
