Does anyone know where I can get schematics and detailed specs for IH (Charter Oak) CNC mill controllers made around 2009/2010? Got it mostly figured out by now but I would like to get the specs of the servo encoders without having to disassemble the housings.

Thanks

ps. Someone moved my original post into the "benchtop machines" category for reasons unknown. Please leave this post in Charter Oak. It's not a benchtop machine.
