I'm trying to make a rectangular pocket using MillWizard (2.0.5 although it says v4). I want the outside of the pocket to be defined by the corners (0.5, 0.5) and (1.5, 2.5). I pick SW corner and parameters Xorign: 0.5000 Yorign: 0.5000 Length 1.0000 Width: 2.0000 and a 0.250 end mill. I wouldn't expect to see negative coordinates in the Gcode but I do. Is there something I don't understand about this? Here is the Gcode file:
