Kiwi-
My machine uses these codes...incremental offsets (both G58 and G59). If you're looking to repeat the same program you'd change it to:
(ORGX58=?,ORGY58=?,ORGZ58=?) The ?s being the incremental moves...if you're looking to move the part over 1" in X only and repeat the program with a deeper Z depth of, say, .25 you'd change it to:
(ORGX58=1,ORGY58=0,ORGZ58=-.25)
G58
(RPT N100,N400)
Hope that helps.
