Over and underextruded solid top layer
My solid top layers are both under and overextended at the same time. Has anyone any hint?
Flow is tuned. PLA @ 210, 60mm/s top layer and 1k acceleration, 60% fan, VC4 idex

Any ideas?
I don’t understand this..
When I do a test print with one solid bottom layer, 2 infill and 4 top, I got a perfectly smooth top surface
And next time I print the real model I get again the over and underextrusion pattern
I have also this issue that the first layer gets worse over time and also there the weave pattern: https://discord.com/channels/582187371529764864/1315742724221304903/1315742724221304903
Wasteland 😂
some additional information:
my slicer project
Anyone?
@Helge Keck do you have any additional idea? I am not sure if this is related to the first layer issue: https://discord.com/channels/582187371529764864/1315742724221304903. Mesh is now within .1 range
Flow is perfect except those areas
One more with over and underextrusion very close to each other. Underextrusion at line end. Layer height 7.16; monotonic infill and 38% overlap
Are we related by any chance? https://discord.com/channels/582187371529764864/1318247769806471168
One more (bottom right overextension). I am not almost at 8kg wasted PLA 😦
Has anyone an idea?
Is that just visual, or is the plastic actually warped much? Like, is this just a cosmetic issue?
These are under = physical gaps and overextrusion = waves/lumps at the same time on the top layer.
Interesting is that if I print the exact same shape on the same VC4 in just 2mm (cutted of from the top), then the top surface is perfect
From 2 to 10mm z is enough that the top surface is not perfect anymore
