The only stupid/ignorant question is the one that isn't asked!
...so in that frame of mind...

Maybe I missed something, but if I have a VCP file using lets say 3 different tools (e.g A V-Bit, A Ballnose, and an endmill), and save as g-code for Mach3, then import to Mach to do my carving, will Mach automatically stop and tell me to change tools when necessary? (Maybe a pop-up window?...I don't have any Mach experience yet).
thanks
