Has anyone retrofitted a Biesse machine?

We have a Biesse Rover 20 point to point machine that runs on NC410 programming by biesse. It's a okay program but I'm trying to get all are machines to run off of Bobcad20 and Mach 2.

Anybody ever change out a system?

Does this have horizontal drilling spindles as well as vertical? ATC? I don't think you can program the drilling spindles with standard Gcode in Mach2/3? I could be wrong, though.

Yes it does have both vertical and horizontal.

Are the drilling spindles and router on the same Z-axis? You may be able to use M codes to turn on or drop individual spindles, and use G1 moves to drill. Programming in BobCAD to use the spindles might be tough. rewiring the machine to interface with Mach2/3 would not be an easy job either, I don't think.

Does the machine work fine right now?

We just brought a Rover 20 NC 410 on the floor for evaluation and are not sure we are going to retrofit it. However, we run a Thermwood C50 with Galil controller / Camsoft package and One CNC Mill XR for Cam.
WE recently added an air drill on the Thermwood and drive it as follows ;
Piggy back of on of our two Z axes, Fired with M codes using offsets to avoid crash between Z head and drill. In our code, the drill is basically a head driven on a common axis ; Router = T1, drill = T3, driven with all standard G codes. It really was rather easy to implement and works great.

Any tips on the NC 410 would be appreciated ....
