I run a Partner 4 mill, with a Cent 5 control on it.
If the machine is run for any length of time with the the feeds and cutter rpm way up, the screen flickers, then cuts out. If allowed to continue, the control would eventually stop in place, and the machine had to be reset to continue. Minor PITA. Kinda figure the issue to be heat or a voltage drop due to loads.
Once that was determined, we found that we could afford to wait the extra minute or so, vs. having the machine crap out. Dunno if your symptoms will behave the same, but we found that lowering the rpm and feedrate allowed the control to carry on. Have not bothered to dig into it further, as we rarely need to run the machine as fast as all that.
I installed a 17" Philips LCD in a frame over the front of the control, and just left the original monochrome CRT in place. The Philips screen auto adjusted itself to the resolution it was being fed by the vid card, and has been a great mod. In addition, we got color, rather than the shades of yellow that we had before the potting fell apart on the back of the CRT.
