Using a keyhole tool

[WillAdams (William Adams (Carbide 3D))]

This work-around is no longer necessary, now that Carbide Create v714 and later have added a Keyhole Toolpath:

Carbide Create V7 Question- Keyhole toolpath

I’ve seen more and more references to people trying to work out how to make keyholes in CC. We’d be open to adding that as a toolpath in V7 so I’d like a little feedback. To simplify, we’d probably define the location with a circle, like the drilling toolpath, and then you’d define how tall you’d like the keyhole to be, and what direction from the center, Y+, Y-, X+, X-. We’d probably implement the toolpath as a plunge, line to the end and back, then a retract. We would not offer to “expand”…
