My spindle is calibrated to move 25.4mm to get 1in of travel, so assume if I increased my numbers 25.4 times I would get what I want. Except I don't want to go through my files and convert them manually.

Am I missing something to get files to run at a 1 on the display = 1in ???

Thanks for your responses so far guys!
Does the code have a G20 in it?
