CFS upgrade kit issues with my K1 printer

Hi, I am trying to install the cfs upgrade kit to my Creality K1, I have installed it but when doing the self checking / leveling is giving me an error saying that filament has been detected in the extruder to unload it before doing a factory reset, there is not filament in the printer or any jam as the filament is extruding just fine, is anyone having the same issue, is there a solution to this, thanks

I have just encountered this very same issue after fitting the upgrade to my K1 Max. I have no filament loaded. There has not been any filament put through the new extruder yet. If I place a piece of filament into the extruder a blue led on top of the extruder lights up.

Many printers are giving the same error, you need to contact Creality and keep contacting them as the CS is slow, i have been waiting for over 1 week and still no solution, i think this is a hardware issue, some sort of problem with the toolhead pcb board or something like that i hope you get it sorted soon my friend

I have sent a support request to Creality Support and contacted them via Facebook Messenger. It is the weekend so probably wont get a response any time soon. Thanks for the reply. At least I now know I am not alone or worrying that I have done something wrong.

Hola, yo tuve el mismo problema despues de imprimir 3 cosas, lo que hice fue desmontar todo el sistema de extrusion, abrirlo y limpiarlo bien, verifique que el pcb estuviera en buen estado y que no estuviera atascado. Despues empezo a funcionar perfectamente.

En mi caso fue facil porque siempre tenia el led azul encendido. Probar a ver si de esta manera solucionan el problema
