I'm trying G-Wizard on the free trial and am wondering....

Can the software run on a PC that is not connected to the internet? The trial seems yo run as a web based app.

Are any bench-top mill users derating the HP value to account for lack of rigidity? If so, any recommendations for the X3 platform.

And I'll toss in a tooling question while I'm at it.

Any love for the Atrax solid carbide 3 flute end mills? Would this be considered a high performance cutter for g-wizard purposes?

Thanks in advance for any thoughtful replies.
