Hi, I'm UM2 user in Korea, so please understand even if you can't read my English.

My problem is bad output of UM2

I've used UM2 about 1 year, but I can't get anyting from my 3D printer.

Please watch these images :

I've changed filament and nozzle(new) and PTEF coupler.

But It still doesn't work!

And I cleaned knuckle of extruder, and changed setting of filament diameter from 2.85mm to 2.95mm

How can I do more?

Please help me!

    Some other user might help you more but for what I see the ptfe coupler and the metal part need 1mm space

    Think indeed you need to create 1 mm of distance between the PTFE and the Hot-end-isolator (metal part with holes). You do this by turning the hot-end-isolator. You may need the heat the nozzle a bit to be able to.

    another thing, why did you change filament diameter to 2.95 ? is it because you actually use thicker filament? if so this can be a reason for under-extrusion due to higher friction in the bowden tube, you should better stick to 2.85 mm filament.
