Clogged bowden tube , cleaned but..

[Adriano]

Hello !
Well for some reasons my A10 printer decided to drive me crazy because the bowden tube got clogged. So i decided to see if anything about cleaning on Youtube and there are tons of videos. Following a video regarding the Ender 3 (basically it's the same printer) the person on the video unscrew the tube "stopper" at the top of the extruder and pull out the ptfe tube, then unscrew the nozzle (and clean it ) and he pick a spare ptfe lenght and put it through the extruder, ALL the way , from the top to the bottom , to "push" residues etc out . I've done exactly the same but the ptfe tube STOP , likely where the heating block is. That said...i think the man on the video has a "full metal" throat on the ender 3 extruder but we have the one with the ptfe tube inside on the A10 ? Does anyone know what throat the A10 extruder mount or have a picture/link for ? I think there's something who make a "gap" on my extruder, i have to clean it at kinda every day...thought it was because the plastic feeeder, so i've mounted the Geeetech aluminum feeder (it desn't fit well, if someone decide for the upgrade you have to work around with it..) but it's still the same. I'm printing PLA only (Geeetech PLA, white, i love the result!) at 210° , bed at 50 - 55° . I should receive some Capricorn tube to see if anything better. What i do when rebuild the stuff is : i screw the nozzle full, then back something like 1/8 turn, then i put the ptfe tube, all the way down ,secured with the "stopper" and THEN i fix definately the nozzle . I think this is the right way but still...let's see if with capricorn tube things goes better. Oh, this happened since the temperature gone wild here in my town...today we have 41° Celsius...Anyway...id like to know wich kind of throat the original A10 extruder has : if full metal or the one with the ptfe inside.
Thanks in advance,
Adriano

Hi, You can refer to this video to clean it up.https://www.youtube.com/watch?v=evslMa5Jpc8
The Teflon tube needs to be fully inserted,
otherwise, it will cause a blockage.
I hope this can help you.

Hello,
Oh yes, i know all Geeetech videos . Well the teflon tube don't "slip" anymore ..it was because the coupler so i fixed the plastic part of the coupler with a cable zip tie . There are "clips" to print on Thingiverse but the zip tie work nice
