Hi Jon... a friend of mine bought a Mycenter 0 with a Fanuc 0M controller and does not have any schematics for the power supply, amps, main controller, etc. During the boot sequence, some of the internal boards light up their leds, but the control panel & crt never light up or come online. Perhaps the ps is not delivering all the voltages needed to boot all the way up?? It would be nice if we can repair the existing ps enough to use the machine as it is, but at what cost? He is trying to bootstrap himself into business, so funds are limited. > The EMC crew did a Mazak > Micro-Center V at Roland > Freistad's shop in Galesburg, IL some years ago.

I think you are right.

I don't know if it is possible to mate these to different amps, or if it is possible to drive the Fanuc amps using an analog reference or pwm from EMC2. Have you any experience with this? Thanks!
