@ahoeben -
Wow, I never would have thought to select the file type. Seems like it should be able to figure that out when I click on the file. Oh well...
When I do that, select my .gcode file (the one linked to above), I get the error: "Failed to import profile from (my gcode file): Expecting value: line 1 column 1 (char 0)". The first line in the file is "M190 S50.000000"
I'm using Cura 2.3.1.
