The first 3 week the printer whit cfs was working well. i had to print a big project whit the same filament so i started to use the lateral spool instead of the cfs.
Now i can print only from the spool and not the cfs. When i try to extrude from cfs the filament is loaded correctly , but when start to extrude is look as the motor of the CFS and the extruder is not synced . when i look the upper part of the extruder i sow the tube is moving like the cfs is pushing but can’t go, after i got and error.
Usualy the first error is Software-triggered sustained overcurrent followed by an error jammed.
After the error whitout doing anything if i make retract the filament everything is fine or if i extrude from the lateral spool everything work perfect.
I think is the buffer that is not working. (opened checked cleaned and look fine mechanical).
The blue light is always on, (i don’t remember if when trigger the stop have to turn off or change color i can’t check if working )
I already changed :
The filament sensor above the extruder,
All the ptfe tube. (verified the filament goes smooth)
The Noozle
Thanks
