Different concentrical pattern on 2 computers with IDENTICAL settings??

[kayazuki 1]

I'm so curious which super knowledgable person can answer this one!

 

See image; I have the same Cura installed on my Macbook Pro and on my Mac Pro..

I may have started from 2 different default profiles (I don't remember), but as Category selection, I've selected "All" on both machines.

 

I have compared ALL the settings and all settings and values are IDENTICAL.

Also the 3 post processing plugins are identical and setup identical.

I've also installed the Linear Advance plugin on both programs, with the same values.

Printer settings, Extruder settings, material settings: EVERYTHING is the same!!

 

But in one program I get this strange messed up "connected" version of the concentric initial layer bottom pattern.

In the other I get a "normal" "real"concentric pattern (which I'm looking for)..

 

Who knows what setting is causing that strange "connected" concentric pattern???

I'm completely lost..
