overextrusion at beginning of print
Hello,
as you can see in the pictures, I am having issues with overextrusion at the beginning of my prints. Do you have any ideas which setting might cause this?

This could be a to low z offset
You can activate first layer compensation in your slicer

Thanks, but would this affect layers at rhe top?
The round part is 140mm tall and the cube was turned upside down (so the pictures show the layers 16mm-20mm)
A few layer after the first layer yes maybe up to 3/4 layers
Can u send a pic of the bottom of the block to see the first layer
U need to get a nice flat surface as the first layer with no gaps
And no ridges

Then this is not the problem. I don't have a picture right now, but the phenomenon occurs at the top layers (150-200 layer) also
I think too much material is extruded at the beginning of the perimeter, but I can't figure out why

Can you post the gcode? I think you might be having same problem as me. Blob on perimeter start after doing a gap fill
Did you calibrate your pressure advance and your flow rate?
rare-sapphireOP•2y ago
Yes and yes. PA is at 0.04 and the flow rate is also calibrated
That might actually describe my problem
I will post it this afternoon
This could be related to bad retraction settings
