Printing quality is so bad

Recommended Posts

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!

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.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
