Olá
recentemente comprei uma K1C, porém quando estou imprimindo depois de cerca de 1 Hora e meia ela para de exteusa.
Tenho que abrir a extrussora para tirar o filamento, alguem sabe o que pode está ocorrendo?
Which type of filament and is it snapping as it goes into the extruder? Gut feeling is wet filament.
Hola @Jose_Paulo_Reboucas …! 
¡Bienvenido al foro de Creality…! 
Another thing to check is if it’s PLA make sure the cover is off while printing… PLA doesn’t like heat and it will soften up and not be able to push through the extruder holes… 
And here is the Spanish version. I hope it’s accurate… 
Otra cosa a comprobar es si es PLA, asegurarse de que la cubierta esté quitada mientras se imprime… al PLA no le gusta el calor y se ablandará y no podrá pasar por los agujeros del extrusor…
hello.
Thanks for helping me. i will test both cases after these answers i will post feedback.
