Is G70, G71 and/or G72 on Mazak lathe controls too?

[@cnctrainingcentre603]

Yes when you use the ISO option it all works the same on a Mazak

[@highlander67gt92]

@@cnctrainingcentre603 cool thanks!

[@TomErickson-kc6uh]

Where would you put in your G42?

[@cnctrainingcentre603]

On most fanuc controls you can't put it in the G71 you have to add it before you go back in and use G70
