Under Extrusion and Bad Output

[sw-jeong 0]

Hello,

I'm using UM2 from 2 years ago in Korea.

But recently, My UM2 have a trouble printing my cad data.

I'm using two of UM2, but all the machines make problems.

Here is the photo of output.

What is the problem?

This is my CURA setting

Layer Height : 0.1mm

Wall Thickness : 0.8mm

Top/Bottom Thickness : 0,.8mm

Infill Density : 20%

Enable Retraction

Print Speed : 60mm/s

Travel Speed : 120mm/s

Enable Support

Placement : Everywhere

Enable Support Roof

Support Roof Density : 100%

Adhesion Type : Brim

Brim Width : 10mm

What is the problem? What should be different? Those look okay. I can think of some improvements - especially I wouldn't do so much support. But what's wrong with these? Maybe circles and arrows on the photo and some words?

The support seems to be under extruded, but still functional so maybe not a real problem but not as it was intended. Maybe the support is printed too fast?
