For anyone who needs a manual for a MyCenter-0 see the above link. I purchased a 1989 Mycenter Zero in January 2017. Now I am attempting to convert it to LinuxCNC control. I had to replace the z axis servo and amp. I did so with a Delta servo 750w with brake.
I have also replaced all of the airlines as they were old and brittle. Mercury 60 hp bigfoot manual start. I pulled the Kitamura System 1000 with Fanuc O-M controller and have replaced it with a touch screen PC booting Linux. I am currently working on getting the spindle and axis servos connected to the Mesa 7I77 so that I can get to the configuration portion of this conversion.

Problem. Need Help!
Folks, I just picked up a used Kit MyC 0 for a song. The machine is filthy, but fundamentally operational and mechanically sound (I haven't put it through all the paces yet), so we'll just call it an elbow grease discount. Operator panel abuse needs some attention and such, but otherwise its OK. I already have all the Fanuc manuals that would pertain to this control, but the machine didn't have any of the Kitamura manuals (operation, maintenance, etc.).
I hate to be another one to ask, but does anyone have a set of manuals for such a machine? This is an early 1990s model(as best I can tell, DoM isn't on the serial label, where you would expect it to be).
With a 'standard' table and access doors, not one of the sparkchanger units. If you have electronic versions, paper versions, anything that you would be willing to rent or sell, PM me to see if we can work something out. I'm sure I can figure out the Kitamura specifics on my own given enough time, but I'm hoping to shorten up the learning cycle by getting access to some of the documentation. I have a call in to Kitamura to get pricing for a set of machine specific manuals, but from what I have read, they're going to expect me to fork over way more money than any rational person would be willing to pay for that stack of dead tree pulp.
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 Bad Z Amplifier. Thanks for the help. The spindle is 230v 3 phase AC 2.2 kw continuous (3.7kw for 30min). It is a brushless servo with position control through a D/A converter.

D/A Converter I/O I will work on getting the manual scanned. The UVW will be commutation signals for the drives. (brushless motors are commutated in the drives, not in the motor).
If those signals exist then the choice of drives is much expanded. Is there a DC power supply in the system, or do the axis drives take AC input? I suspect that the easiest solution would be though cheaper options include the Mesa 8i20 (requires separate DC power supply) and 'Whatever turns up on eBay at a good price' It might well be simplest just to find a stock of spares of the original drives. Thanks for the education.

Servos and their drives are new to me. The UVW does exist in the encoders, I've seen the connections with my own eyes. These drives take 200V AC +-10%. I checked them yesterday and they are receiving 189V. I'll research those options. I have to go back through and troubleshoot it again as I keep getting different faults depending on my jog speed settings.
It always faults out while trying to reference the machine so I have no idea what shape the x and y drives are in. On the upside, I have a reasonable candidate for LinuxCNC. 17' Touchscreen panel mount w/serial port.
