Carbide motion ATC cut3d

so trying to carve 3d saw on youtube video reference to “carbide motion ATC cut3d” processor
can not find this anywhere is it a thing

Did You contact the maker of that YT video where it is mentioned?

When you setup any of the Vectric products and you run through the setup wizard there is a step where you select your machine manufacturer and options for post processor for that manufacturer. There are 2 options, if I recall, for C3D machines and one of them of them is Carbide Motion ATC.

I hav no idea how it differs from the other post processor offered but my guess is it has support for the BitZero (or is it BitSetter I get the names mixed up).
