About a year ago, i purchased a Cut3D and VCarve Pro bundle, believing they would fit my needs for generating tool paths at a reasonable price point. Being a guitar builder, all of my CNC work involves either complex 3D carving, or fairly straightforward pocketing.
I'm happy to report that VCarve Pro has been getting a LOT of use for generating tool paths for all of my pocketing/routing operations. I really like the way it works, and the simulations are invaluable.
However, i have not used Cut3D once. The main reason is that limiting the machined area is not possible. This is an absolute deal-breaker, and had i known that it was not possible with Cut3D, i wouldn't have purchased it. (I had assumed that such a logical feature would be standard in a program of this calibre, and should have done more research and/or worked more extensively with the demo version beforehand.)
The reason i need machining limits is that some of my pocketing is NOT as straightforward, and involves complex contours and non-flat bottoms to the cavities, which cannot be done with VCarve Pro's "2.5D" tool set. Generating tool paths for a pocket like this in Cut3D results in a tool path file that machines the entire surface, wasting hours of machine time. As a result, i am now using a different (though slightly less flexible) product that DOES allow for machining limits.
I would like to request that machining limits be added to Cut3D's feature set. It would allow me to use the software i paid for. I use Rhino for my modelling, so the feature set of Aspire is redundant and not what i need.
P.S. Another feature that would be VERY useful would be the ability to set a custom angle for parallel finish paths. Sometimes i have a cavity that is not perfectly aligned to the X- or Y-axis, so a raster tool path often results in a "jagged" wall cut. If i could set my own angle, i could get the smoothest cuts possible. Thanks for listening!
