Post by fl_enoc »

Hi, yesterday the extruder clogged, i had to remove the extruder and passed the filament many times in it, it worked all night. untill 10am when it got clogged again, then all day it got clogged after one good printing. when i check the inside of the extruder i only found a little peace of filament in it, this went on and on all day. in the 2 last prints it didnt improve with the cleanning

Hola, ayer extrusor se bloqueo, tuve que remover el extrusor, lo desarme y trabajo toda la noche, en la mañana volvio a bloquearse, esta vez tambien retire un pequeño pedazo y realizo una buena impresion, para atorarse de nuevo, todo el dia el mismo patron, lo limpiaba para que en la siguiente impresion se atore. En las ultimas impresiones que he hecho sigue atorandose el filamento se extruye muy poco. por favor ayuda

Change retraction to 1.25mm;
Do not remove filament because than clogging will happen. Change the filament by cutting off and feeding new from the top in.

Thanks Bachgassenbande. i did what you say and the print improved a lot. but when i extrude in the panel Manual control it seems like its not enough. im making prints but in some of them i can see extrusion deficiency. thank you a lot

Additional it seems for you that you have a sticking issue with your material.
Get a glass plate (2-3mm thick) apply hairsprai extra strong on it, heat up your bed to 60 or 65°C
Then post again.

If you get constant jams, I recommend taking a guitar string or wire to clean the tip of the nozzle. I'm not exactly sure why, but I've had this happen several times, always after running the nozzle into the bed a little too hard or bumping it.

I didn't figure this out for a long time, and kept wondering why the nozzle jammed every few hours for no apparent reason. Ever since I started flossing, it's all good :)

Also recommended is to calibrate your extruder
