[CAD_CAM_EDM_DRO] Mach1/2 - Tool offset when manually installing tools ??

Hi All

I'm using/playing with the DEMO version of Mach1.

Is there a trick for manually setting the tool offsets
on the fly. (IE: when a tool change is requested).

Since I don't have a pile of R8 tool holder for every end mill
I can't prefab all the tool offsets.

Am I stuck buying tools holder or is there a way around this ??

Thanks
Mark
