Trouble upgrading to 4.2.7 and sprite extruder. I upgraded my ender 3 v1, to a 4.2.7 board and sprite extruder. I updated the firmware using creality 4.2.7, no bl or cr touch. Eveything works but my extruder wont turn, I can push the filament down and it comes out but the filament never feeds in. The only thing I can think of is the board on back of the extruder. Any help would be appreciated. Thanks
