Error on Backside component placement

[Shackmeister]

When having the following input from the POS file:

Ref,Val,Package,PosX,PosY,Rot,Side
"H1","Pogopin_PNP","Mill-Max_Pogopin_0906-8-15-20-76-14-11-0_PNP_DUMMY",16.335000,1.485000,180.000000,bottom

I get the following output in the CPL file:

Please note H1 and H4 is suddently placed in the same position!

@purdeaandrei you seem to know something about the bottom placement algorithm :)

[Shackmeister]

flip_x autodetect, is assuming all components are placed at a positive coordinate.
It's not unusual to have components placed on both sides of 0.
I would suggest we remove the autodetect, and add a suggested export setting in the documentation

[boborjan2]

Could you detail what to set during export exactly? I also experience odd placement on the bottom. Thanks!

[Shackmeister]

Actually the issue is also present on the top layer
Issue is present when part are placed on -X or +Y (in Kicad)
