So the machines are running the Windows based Vulcan software?  If so, yes...you can keep that software.  But take note....

Unless you had CAMduct when you bought the machines and made that a requirement, the Vulcan software likely won't work "as is".

You'll want to check first just in case but you can buy a "file download" option from Trimble for the controls. I believe it's about $3k a license when I last did this a couple years ago.

With that option enabled, you can change modes on the controller so instead of downloading from the main Vulcan database/server, it'll read the NC files CAMduct produces.

The guys is the shop will likely not prefer this because the Vulcan system has some nice features allowing them to rerun a single part all from the control. CAMduct has a "single part recut" option but you need to do it from a CAMduct station and regenerate a new NC file for loading.
