face.py dimensions issue

[yeyeto2788]

Hey!

First of all, awesome set of tools!

I'm not an expert on Gcode nor CNC but I wanted to make the surface of my CNC with the face.py. It seems like it's adding the tool diameter to the whole perimeter so if my board is 50x70 I'll end up flattening a surface of 53.2x73.2 which s caused by (50 + (1.5 + 0.1 forward) + (1.5 + 0.1 backwards)) x (70 + (1.5 + 0.1 left) + (1.5 + 0.1 right)).

Is this correct? or the final code generated should go 0 to the max perimeter given?
