ASA print problems

[Monitor_ing 0]

Hello, i've started working with ASA recently because of the UV resistance and other good properties of the material. In the meantime weird stuff started happening on my printed objects. I hope somebody can tell me what is the problem and what am i doing wrong. I'm using Ultimaker Cura v4.5 with Creality CR10 S Pro. Below are some pictures of the problem.

Print settings: Extruder temperature - 255 C- tried with 245 C and same results. 

Bed temp  - 100 C.

Nozzle 0.8mm, 0.2 line thickness.

Fan not enabled

Printer enclosed

  I have also added pictures of cura settings.

Nozzle is lifted 0.2mm from the bed surface. 

Proximity sensor is inductive.

Z axis adjustment is -0.05 mm because if i leave it on 0 mm gaps betweeen printed lines appear.

Not sure I have an answer to your query but one thing to help you out in future maybe: you can export a project file from Cura (File > Save as...) and anyone who opens it will have your exact settings so you don't have to make screenshots. it will export as a 3mf.

 

Off the top of my head your images indicate under extrusion or high nozzle temperature. Perhaps you could use one of these preconfigured profiles https://marketplace.ultimaker.com/app/cura/materials/3DXTECH/3DXTECH_ASA_2019

 

They're optimized for UM machines but you could use as a basis for your machine.
