Extrusion seems to start too late with 0.6mm nozzle
Hi Prusa Forum.
I have a strange issue that I am trying to solve. It seems to me like my extrusion is just a bit slow to react when it starts printing a line. This is with a 0.6mm nozzle, on a standard Mk3s+.
All advice and articles I've managed to find that relates to the issue, points to linear advance and extrusion multiplier settings. Linear advance is on default and seems to be correct if you look at the attached picture of a test print. Extrusion multiplier is at 1.05, obtained from doing the calibration tests and measuring the prints with callipers. So they both seem to be correct.
Have a look at the picture attached. Look at the left starting point of each line. See the gap where there is just nothing when the print line is starting? That is the problem. It results in nasty seams, and creates blobs and things everywhere there is a bit missing on the previous layer.
I did not notice this problem with the 0.4mm nozzle.
Please help?
Kind regards, Wietsche.

Hi Wietsche,
Would it make sense that you share a zipped 3mf example in a way we can compare your parameters with ours?
Regards

Sure, I can do that. Any 3MF print file? Or the linear advance test? For the linear advance I used the GCODE on the prusa site and changed parameters to 0.6mm nozzle, like instructed. I can share that file, but have no 3MF for it.

Pictures of actual print issues. Late extrusion opens up seams on round shapes:

Suggestions would be appreciated, thank you.
