Hello!
since a few days my nozzles frequently are clogging with some strange dirt.
When I get it out, it reminds me to sand.
I have a dust cleaner just ahead to the extruder.
But this stuff comes through.
Any idea to prevent this?

The printout I mentioned in my last post looked this way:
just after about 10mm it got messy and then it printed on as usual.
Maybe the white stuff is too humid?
After this, I took a spool from GRR and it was fine.
Oh, yes: the hotend is PTFE and brass, so no Bakelite.

When I changed the nozzle, I manually extruded some filament without nozzle,
it looked this way.
I'm curious where this dirt comes from.

Hello botfeeder,
good suggestions. I already store my filaments in large (15 liters) buckets with lid.
I also put a bag of air dehumidifiers into the buckets. I have a humidity of about 35% in those buckets.
I do not have pets here, so the risk of fur hair is down to 0%
I just got an Idea: Instead of a complete case, I could make a cover for the spool (a round tupper pot with lid or a cake cover)
and a tube for the string that goes down to the extruder.

Great, keeping the filament as dry as possible is the best way to keep it fresh.
I usually keep my opened filament in my electronic dehumidifier and keep the filament in the range of 10-15%.
haha, I have a dog at home, so I have a slight fur problem. I build my printer a case. With the case I can even heat up my print bed to even higher temperature for better adhesive. love the case.
Yes, making a tube like spool case will work. Just make sure the cover would interfere with the feeding process. Enjoy

Hi botfeeder!
I'm happily printing without the cleaner since days now. No problem at all.
But the orange filament seems to be a bit too humid. I can hear the water bubbles
exploding while printing.
So this electronic dehumidifier makes me curious. What technique do you use?
Kind of a air condition and cooling down the air until the water condensates?
