I'm the proud owner of a Mitutoyo 3D CMM (Coordinate Measuring Machine), Model C806-10, vintage probably around 1995. Has a heavy cast iron base (forming the X-axis), upright (Z) and cross (Y) beam, containing a bunch of fancy THK rails and linear bearings (unfortunately rusty, but hopefully not irrecoverably so :-). Spans a volume somewhat less than a cubic meter. Movement is manual via hand wheels and rack & pinion gearing. Measurement is done optically with (chemically etched?) stainless steel gratings along the rails and small (~1x1x2") read heads.
All of the external electronic gear is gone, so I'll have to handle the signals from the CMM myself. Intend to use standard microprocessors (e.g., Microchip PIC or TI). Suspect I'll be dealing with a more-or-less standard A/B-channel quadrature pair. (Been there, done that, standard ICs make it easier...)
But I don't have any manuals or other documentation, such as wiring diagrams, schematics, interface specs (supply voltage, signal levels, etc.), connector pinouts, etc. I can reverse engineer the interface boards, but it's more reliable (and a lot less work :-) if I can find the appropriate docs.
Can anybody help me?
I'm specifically looking for tech info on three types of Mitutoyo components (if not the whole CMM):
1. Optical read heads: no part number, but serial numbers like "880876"
2. "TF-AMP3" PC Board, with what appears to be part number, "MP-121201".
3. "REF AMP" PC Board, "MP69006"
