I have several parts to make in mirror pairs. In reading the Mach3 manual I read that setting the Scale on a DRO axis to -1 means all readings are in the opposite direction. Does this mean that I can use the same g-code program to make a part's mirror by setting the scale of either the X or Y axis to -1?
I assume the G2/G3 words would need IJ rather than R format, but that's not a problem. However, the program would need to scale those values as well as the X or Y.
Does the scale function allow me to reduce/enlarge a part overall?
