Infill visible on outer walls and something like z wobble

Hello,

I have a question. I printed some parts and discovered that the Infill is visible on outer walls. I printed with standard ABS parameters (perimeter: 2).

 

Has someone any idea why this happens? I also have something like z-wobble mit it's not from z-axis. I was able to solve a part of this problem by doing mesh bed correction.

something like z wobble?

RE: Infill visible on outer walls and something like z wobble

For infill print through easiest solution is adding a perimeter or two. 

For wall variations, the ones on you part look like speed variations due to a variety of part conditions. Can also be slice control of print movement direction.  Some of us have found turning down the detection of layer print speeds can help smooth wall printing; also slowing down the perimeter print speed is helpful.  

There are threads discussing these artifacts -- search for "Bulge" and read this rather thorough discussion:

I tried with 3 perimeters, but same error.

Maybe it's also because I used tinkercad for the objects and the algorithm is not good enough.

 

For the walls: I will try this, thanks.

This is the number to change for layer speed slow down for cooling...

Tip: In the sliced view, change 'feature type' to 'speed' and make sure all your external perimeters print at the same speed after changing the above setting.

Hi,

I have no access to this value because I disabled automatic cooling.

I use for ABS cooling fan speed 7% and Bridges 25% (if I change cooling speed bridges nothing change).
