Just installed the Creality Direct Drive Extruder upgrade kit to my Ender 3 Neo. I followed the wiring diagram and the “official” online video. When the printer is switched on it now immediately starts to beep and a message is displayed that states “Err: MAX TEMP REACHED E1”. When I put the original unit back on it works without any errors. Are there any things I can do to fix this - or could it be that that kit we bought is faulty?
