I have ender 3 pro. 4.2.2 MB. I recently upgraded to the Sprite extruder pro and BL touch. I followed instructions for installing both. I updated the firware to the new hardware. When i go and try to level the bed, the printer moves to the “Home” location and then back to the center and does nothing. It doesnt even change the Z position to go lower.
The BL touch does light up red but does nothing. Ive tried searching for more info. BUt coming up short
