@dylanmc said in Scale issues with gcode output:

Make sure you're in "mm" mode - this code only runs in that mode. If you're in inches, pt, or cm mode, it won't work.

i'm in milimeter mode. that's why i'm founding it so confusing. anyway
this is print screen of my document properties

edit:
so i do some simple math (man know maths!)
my model is precisly 100mm long
gcode output from inkspace is 30mm long
magic!

edit:
