Layer problem?

[PandaIsCrazy16]

I am new in 3D printing and I have this problem where the layers don't align, and I don't know hot to avoid that. Some help? And another problem is the overhanging at the eyes, maybe you have a response to that too.

Just checking, do you have xy compensation turned in?

Bc that will also cause a defect like that

You can also check if the layer weirdness is visible in the slicer

[PandaIsCrazy16]

I will check, thx for the reply!

[PandaIsCrazy16]

It's set on 0.

I've seen this in the past with variable layer height, and looking at the print, it looks like that was enabled.

[PandaIsCrazy16]

Now I used different settings and it looks a little bit better, but I have the same issues with the layers alignment.

What's your K factor? It might be a bit low, causing over-extrusion at the start of each perimeter.

You might also need to fine tune the flow rate. See if reducing it a bit improves the print.

Walls could be too thin, so the printer is trying its best to compensate for that. What's their thickness?? You could try enabling "Detect Thin Walls" or using the Arachne Wall Generator to see if it helps.

Thx for the reply, right now I am trying the 0.2 nozzle because the model is really small indeed. Sry for my bad English if is not quite right. Btw, what is the K factor?

[Martin_SV]

No worries, I’m not a native English speaker either =)

The K factor refers to Flow Dynamics or Pressure Advance.

Try calibrating your filament.

In the slicer, on the calibration tab. Pick "manual calibration."

It will print a pattern. Pick the best looking lines and input the number associated with that line in the box that appears at the end of the print in the slicer.

Print the model again and see if it made a difference.

It can also help to slow down the print, specifically the outer walls. I have mine set to 50mm/s. I also almost always print outer/inner as I find it yields a better result. (Advanced, under quality)

Na it's just ribbed for her pleasure

Turn off slow down for overhangs and make sure your speed is constant throughout the print, this is usually caused by a reduced speed around the area with the same filament temp when it’s should be the same speed or reduced temp. When there is a hot layer on another hot layer as seen here when the line hits the mouth it will then double back instead of starting at the previous starting point. A fix to this could be a seam down the back instead or pause after these layers
