Thank you, i raise to 0.300 instead of 0.200 and solved my problem.
Still model come with imperfections
Bottom layer come all good, no imperfection
With this setting i got a bit less of strings, still not that less.
Also surface is not clean as other filaments, a tiny dot of filament is left on top layer but that can be easly cleaned, no more than 20 dots.
And last it left some scars on model
Seens this PETG melt at lower temps, i’m using the max recommened 230-235 but it works at 190. Can this be a problem in terms of resistance?

I print this without setting overextrude overall, my calcs give 1.11% rate but i print a test model and come worse than 1%. Also in octoprint i use to extrude 100mm at 111 rate and it stop exactly at same position if i use prusa lcd controls to extrude 100mm. Can’t understand this, if flow rate is 0.11% more why it stops exactly at same height?
