Anet A8 Sudden print quality issue
Hello all,
I'm hoping someone can think of something I have overlooked. I have spent a lot of time dialing this printer in and was really happy with it until I suddenly started having problems with layers missing their outer wall. Strangely it seems to mostly to affect recessed walls. The cube picture shows a cube I printed a few weeks ago and the 2 on the right are cubes I just printed using same settings but have annoying flaws. The other picture is the print in which I started having the issue. Hopefully someone here can help cause I'm at a loss.
Things I've tried:
Bed/z axis leveling
Replaced nozzle
Used different filament (different manufacturer)
Check extruder for debris
Tried different spool holder (3 different types)
Calibrated extruder steps
Made sure motors are secure.
Printer Info:
Anet A8 (old acrylic frame)
Glass bed
GT2 rubber/fiber glass reinforced belt
Polymer shaft bearings

I think I have the same problem. I tried to make some litophane photo but as you can see on the pic attached, a have some missed lines on the right side of the print.
So Hope I can get answer here for this issue.
Have a nice day'

I'm using CURA 4.4. I was actually able to nearly eliminate this by tightening the y axis belt beyond what I normally would do. I'm still seeing a very slight almost imperceptible shadow of the issue but I was able to reprint the Eiffel tower that I showed in the picture and I happy. Is it possible this really was a belt problem that only affected those layer on just those faces? the back of the cubes I showed look good.

I have updated the belt , I mean print a tensioner for it. It work perfectly the belt is tight enough but after the belt update I have the same problem. I'll try next to check the under extrusion maybe that's the problem and come back with an answer

Hi again,Finaly I think I have resolved the problem.-I have updated the Cura to 4.4.1 ( I don't think that this was the problem)-I have observed that I didn't set up a material profile. So I set up the profile regarding to the PLA I use ( Gembird and it has the mat. specification : density etc)-And last I have raised the hotend temp. It was 200 celsius, I have raised it to 210 ( I have read somewhere that the tempcontrol read less celsius than realy is)So as you can see on Pic attached now the print is smooth (I think )
When I have time I try another litophane and come back wiht a result .
