It is a copy of my message : https://groups.google.com/d/msg/wanhao-printer-3d/30XbEh81yjI/rlw51dHvAgAJ
Hello Gary, I have a problem with extruder. You can show video on facebook group https://www.facebook.com/mathieu.fabris/videos/10153611916964599/
Printing starts normally. But after a moment (about 50% of printing): gear and bearing make sound “click clik” and It can’t load filament. It seems to be blocked in tube ptfe/throat/pipe/nozzle.
I need to abort the print and the filament is stuck in throat:
I need to click on “Tune >Abort” print
Maintenance > Advanced
Lower builplate twice (x2)
Unscreew the 2 hexa screew for throat/pipe
cut the filament blocked/stuck in throat/pipe
unscrew the nozzle
Cleaning the nozzle with gaz light or blowpipe (after I can see through the hole. The interior of the nozzle is perfectly smooth and clean)
Cleaning the throat/pipe (after The interior of the throat is perfectly smooth and clean)
Cleaning the PTFE Tube (replaced already 2 times)
I assemble all the parts
And to start a new print I need to do this steps :
Maintenance > Advanced > insert material and I test loading with > move material.
I have checked the gear ( the wheel notches seem to be clean).
I have tested 3 Brand of filaments (Wanhao, BQ, ICE)
I have tested on 2 spool holder of filament
In both case, The filament unrolls successful on the all spools (proceeds without force )
I have order 2x MK10 nozzle to test in 3 days his remplacement.
Do you have an idea ? a solution ?
Note: 2 screws on X and Y axis were unscrewed !
I permanently banned BQ and ICE PLA filament.
Now I use Wanhao and Hatchbox filament
Thx for sharing this information. Had the same problem twice using “Prima Select” filament (PLA, black, print temperature: 210 C). Did the problem reoccure meanwhile using Wanhao and Hatchbox filaments?
