[Under extrusion after every layer change]

I think I may have solved it! Is it possible that there was a section of very fine lines before the retraction that causes your issue? I believe that during these very fine lines, filament oozes away DURING printing, causing ever so slight overextrusion in the structures prior to the retraction! So after the next travel move, the nozzle is empty and has to first fill up before the print can continue as normal. Usually, these defects occur in infill and are not visible in the finished print. This is unless there is no infill, either because the print is very thin and consists of only walls, or because a part of it is narrow and made up of only few lines to begin with! That is also why this issue shows up besides holes so often. I can't believe I may have finally figured it out

I have a similar problem. I printed a pumpkin with eyes and teeth and the more layers are printed, the more i get those empty lines. Later on everything is okay again.

How did you solve that?

Thank you for your answer!

I read about Ironing but wasn't sure, if i should try. But i will do and give feedback on this.

Cutting with a craft knife might end up with a worse result then the top layer actually is 😉

 

[Top Layer Problems]

Hi!

I hope to find some help here, as i get a little frusted i can't solve my "problem"

I use cura to slice an object i like to print.

My object is for example a flat cube with some holes/cut outs. The printer now prints a part on the left side, a part right on the right side and last it prints the middle part of the object. This causes an uneven top layer, because there is a kind of small seam or small gap between the parts. Like the space between the lines changes there because the printer prints close to the last line or more far away from it. How can i solve this? I changed the direction of the pattern in cura,so it looks a little better, but it's not solved.

Any ideas?

My settings:

PLA: 1.75

Temp: 195° (190-205 tested-not successful)

 

Layer Height: 0.2

Flow: 100% (decreasing flow doesnt make it better)
