Fan stopping when klipper shows 70%

I'm having issues where the part cooling fan stops completely while klipper shows 70%, I can't figure out what is going wrong.
I'm using orcaslicer 2.2 and latest klipper/ratos.

When I'm not printing I can control the fan perfectly with the slider from mainsail.
Anyone has any ideas? In the slicer preview it never goes to 0% fan.

I also saw the post processing step for the first time in klipper before starting a print, might that have to do something with it?
Here is a gcode snippet;
