QUESTION Retract Tower Extension vs. .stl Part

[Salty_Doug 0]

Hi,

I am using Cura 4.9 beta for slicing. I used the Extension "Part for Calibration" to make a Retract Tower. I used the settings "start at 0.0mm and increment by 0.5mm". I have an all metal hotend on my Maker Select Plus 3D printer. The part came out perfect with no stringing whatsoever. Refer to the attached pictures. 

I have a .stl file created in Fusion 360 that I use for the same purpose. I sliced the part with a retract setting of 1.0mm. The part came out with very fine strings, picture attached. I have looked at the GCODE files for both prints, but I don't see where the retract distance is defined.

My questions are

1) how can I adjust the normal slicer settings to match the retraction Tower?

2) Where are the retraction settings in the GCODE file?
