Pattern g code when loading in mach3, doubles in size when cut.
Any ideas on what is going on?

Maybe I have worded the first post incorrectly,
What is going on is, if I load a pattern (G Code) that is say 9.5 inches wide by 4.5 inches high, in the passed it has been cutting it correct. Now I load the same pattern (G Code) into Mach3 it is making it twice the size.
Any setting in Mach 3 that may have gotten changed by mistake?
Have checked everything I can think of, to check.
Any help on what could be going on here?

Only things I can think of that  could do that are your code has a G51 in it or your steps per unit are half what they should be or lastly you have a scale set in the boxes next to the DROs.
