OSAI Numerical Controller Won't Power On

[akitchens]

Our CNC machine has been down all week. The lead time for CR Onsrud to get a new controller in is anywhere from 2-3 weeks and then they will have to set it to our machine. We cannot wait that long and cutting cabinet parts by hand is a lot slower, but we cannot bore our holes as we recently got rid of our old boring machine. We've tried everything we can think of to get our numerical controller back on, but it will not power on at all. Anyone have an idea besides the controller being completely shot that we could try to get it back up and running?

I would visually inspect the capacitors on the boards. If the x in the end is bloated it is gone.

 

Anything beyond that you should get a board schematic.or find someone familiar who knows what goes bad in those units 

One of our mx 520s blew the hydraulic pump for the second time. First they wouldn't sell us just the pump because of some efficiency b/s. So we got one from somewhere else.

 

Then the second time there was a 9 week lead time on a pump and 14 for the whole unit. 

 

We ended up getting a fancy unit with a small pump with its own controller. It seems to run cooler
