Thanks for clarifying that.

Similar things can be done with a KFlop, however not using any industrial standard.
I do have a Mach 4 Industrial license, however I doubt I'll ever use it. Dynomotion have no current plan to develop a Mach4 plugin, and the only controller that might temp me would be a CS-Labs, but I far prefer the flexibility of KFlops.

As Gerry says, anything that's not a true industrial controller, is not likely to ever have macro B.
