[Combing Z Seam Issue]

You talking about underextrusion but I can tell that I actually have overextrusion with my e-steps calibrated to Polyterra PLA and still get those ugly Z-Srams whenever I turn on combing.

 

Can somebody help?

[Abs print keepst on warping :(]

I managed to get it stick with a glue stick without solvent at 110° plus raft shield plus corner anti warp plugin and cooling off.

[Combing Z Seam Issue]

I ran into some weird z seam issues ending with some kind of underextrusion at the z seam. After calibrating my Lin Advance I still had this issue wherever I was using cura. It seems like Combing mode no matter if changing to not in skin causes this issue. 

 

I'd like to understand what's going on with this setting and hopefully someone may explain me what's causing this.
