I'm needing some help with my Hurco bmc 50 mill it has ultimax controls. I can't get it to boot up. The machine was working a month ago and now its not. The monitors are " working" I get different thing that come up (ultimax, blinking courser, and executing start up diagnostics but its on the right-hand side instead of the left. Sometimes the buttons light up and some times they don't. Where do I start? The shop I work at you have to fix your own machines and I'm not a maintenance man so any help would be great!
