Today i bought a second extruder for my vertex k8400 he worked great on one head. So after completing the instal of the second extruder motor and nozzle and uploading the double head software i wanted to prepare the second extruder for printing. Heating works. But loading filament does nothing. The extruder board is fitted corectly and al cables are ok. Software ok aswel. Still nothing. Even tryed the older software version… Still no luck. Any thoughts?
Extruder motor works when i fix extruder cable 1 to it…
