I recently picked up a Masterwood Speedy 207 for next to nothing, it has 6 hours on the counter. I set it up and for what it's made to do, it works beautifully. But, what it does is boring. As in, it bores holes in cabinet parts and that's all, it does not have a spindle. The "Z-axis" is operated by a pneumatic actuator, so it has no real control besides a mechanical stop for depth.

The controller is woefully obsolete, it's like using MS DOS. I doubt there's any way to configure it to add the Z-axis.

I can see the following options:

-Replace all motion electronics with a typical 3-axis stepper control system like WinCNC or Mach 3. My main question with this approach is how to size the motors, the heavy gantry is run from a single DC servo.

-Replace the controller and keep the drives and DC servo motors on the X and Y. Add a stepper or servo on the Z. I would use WinCNC for this if it can run the Axor MiniSpeed 140 drives. If not, Centroid Oak has been recommended. Not sure how to determine the compatibility.
