Clogging inside Unusual spot
It was an air print. I thought I had a clog inside the nozzle. I did clean it, and make it worked. But not long, it did it again (air print). Then I realise, that it is not clogging inside the nozzle. It was inside the printed part above the Bondtech pulley (strange..).
At first I thought the filament is so dirty, so I put a Filament Cleaner ( https://www.amazon.com/gp/product/B00NXIO22S/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 ), but it did not work. It was air printing again.
Then I thought it was the dirt from the filament, when the Bondtech pulley pull the filament. So I make the idler loose. I thought it was to tight, even I did not see any dirt on the Bondtech at all. But, it did not solve the problem.
Please see the video how hard I tried to push the filament in. It was blocked with something I don't know what it is since the filament is Black, and the dirt is grey... dust ?
Any suggestion ? help please....

is that the ptfe tubing?
Re: Clogging inside Unusual spot
I don't think it is ptfe tube, I can tear it.. like a tissue... or is it possible the ptfe tube ?

Could it be too much dust on the filament ?

😮
I think that may be it.

I've had so many nozzles get clogged with dust that I now routinely run all filament through a piece of foam sponge to wipe the dust off.
There's lots of models on Thingiverse for sponge holders, but the solution I eventually settled on is the simplest:
When the reel of filament runs out, I just throw away the foam. It's amazing how much dust can collect on the foam, all of which did not go through my extruder.
