Output a Prep/G-code with fixture offset -- If this machine requires a prep/G-code along with the offset address for fixture offsets, check this box. For fixture offsets that require only one code to be output (i.e: G54 or H01 etc.) do not check this box. If this box is checked the SELECT/gg,ADJUST,nn command is used where gg is the Prep/G-code and nn is the offset number. gg and nn are checked for their minimum and maximum values. (Intcom 3427)
