Re: Newbie questions???????

On the fanucs at work if the toolchange command has the toolblock
number and then the offset number. T0101 and T0102 would change the
offset but not index the turret. We do all the gang tooling like this.
T0203 would be the fist tool in the second station for example.

Let me get this straight, in the current version of Mach, there is no
way to change offsets without having to press cycle start?
