Hello,  I am really new to this prgram.  All my G code has a default 60 z axis for rapid moves.  How do I change this- Also I am using the THC300 plasma torch heigth control and and there skin removed the tab hot button to give me the ability to move all axis manualy.  How can I get this back ( I know that is MACH 3 but thought someone might know how)
