Yeah, but you don’t need any gcode to know that 79mm isn’t going to work. I would guess that 0.56mm is also far enough off to be a problem, but I’ve never measured it. What am I thinking? I’ll go measure that now.
I’m thinking there has to be a problem with a) temp control, b) extruder gears/idler, or c) stepper motor driver adjustment, if it was underpowered it could cause the 79mm too.
