Hello all, I've been lurking and reading for awhile. Now I need some advice. I recently purchased a 1989 Kitamura MyCenter Zero With Fanuc O Mate and Sanyo Denki drives (BA030-04) and servos (65BM004) with a Z axis fault. I was told it was the encoder. The problem was the brake not disengaging. Once that was fixed the Z axis drive faulted with no load, the solution per the manual is to replace the drive.
Instead of fighting this thing through all the problems it may have that I haven't even gotten to yet, I would like to do replace the axis drives and steppers and use LinuxCNC as the controller. I would like to keep the spindle servo and drive so that I can use it to ridged tap and index for tool changes. I found this thread regarding setup of the spindle.

The 12 position ATC and its controls can wait for phase 2. My main goal is to get the axis, spindle, and drawbar operational.
Here is the hardware that has stuck itself in my brain.
Panel mount touchscreen PC (need to load Linux and check latency)
Mesa7I76E
Clearpath SD servos on X, Y, and Z
Optionally I could reuse the amplifier and servos that work with a Mesa 7I77. Any suggestions on a reliable amp for use with the stock servos?
What would you do? Any help is greatly appreciated.
I have built a couple of small, stepper driven, CNC machines before and ran them with Mach3. I was very disappointed in the control and rigidity. I have installed linuxcnc on a couple of computers in the past to try it out. I have never ran a machine with it.
I tried to link some photos of the machine but recived an error stating I have too many links. I'll try more once I prove Im not a spammer
