I posted this in mach mill but not too much action going on there I guess. So since I'm using a Tormach I will post here as well.

After facing my part I have the perfect zero for z. So I zero out z. I then touch the facing tool off on my manual touch block. Now, what buttons do I push (procedure do I use) to enter the offset number from the z dro so that when I manually put a new tool in (I am using collets) and touch off on the same block It will go to and start cutting at zero when I start the program?
