Yes but secret is when you make a change dont save it, use save as instead, that way if you screw up you still have the original. I have about 30 different ones for my lathe LOL, it took quite a while to get it working with front and rear turrets and even yet its not perfect as for a boring bar on the front turret I need to tell the cam its on the rear and for a front turret turning tool for some strange reason the Cam needs to be told its aproaching from the rear.
I have given up messing with things for the moment as I am sure this has a bit to do with the way Mach handles front/rear tools and Brian is reworking things so maybe in about 20 or 30 years time we will have a new updated Mach3Turn to play with
