Hi Mauricio,
Most of the MHx00P series MAHO's connect the axis lead screws through a gearbox and clutches onto a single servo motor. They can not do 3D motion. Check if that is the case on the machine you are looking at. If it doesn't have simple 1 servo- 1axis like the x00E or C series, then you are going to have a lot of mechanical work and cost to remove that gearbox, fabricate and install servo mounts, buy servos and drivers, connect them to the lead screws with belts or couplings, etc.
Basically I'd avoid a MHx00P series machine with that sort of axis drive, and keep looking for a decent MHx00E or C. It is much cheaper to convert a machine keeping the existing drive hardware, (even if it is tempting to use modern AC servos). Make sure you get the electrical schematics for your machine (they vary within a series). You can buy schematics from DMG.
Assuming a MHx00E or C machine with working Indramat servo driver and Heidenhain scales, you need MESA interface cards (5i25/7i77/7i84 is what I used), a PC, and a fair bit of patience as you wire it all up, and then configure LinuxCNC.
Later you can make a control panel, pendant, fourth axis etc.
There is no private messaging thing in this forum. Send me you email address via CNCecke.de, or Practicalmachinist.com where I have the same user name, and I'll send you my draft "how to" guide which summarises everything I have learnt from my build and thread.
