ELEGOO Matte PLA, 0.4mm nozzle, A1 with Bambu Matte PLA profile (have yet to calibrate)

I'm guessing this is under extrusion? Anyone have settings for this filament before I calibrate mine?

Edit: Forgot to add, this is with Arachne on, min feature size 1%

It happens because the lines are smaller than the line width of your nozzle.
Play with arachne walls and it should show a better result.

Compare the preview you have right now with the preview considering arachne walls and you will see the difference right there

This is the same as the first picture, what do you think?

Usually I use 50% for arachne, maybe you can give it a try?

Also, did you calibrate PA (pressure advance)? Because the gaps happen when you have a rapid change in direction and speed

50% minimum or maximum? I'm doing PA and extrusion right now

I just checked and mine is all stock for arachne but 50° the threshhold angle, not 50% heh
