  Is the electrical cabinet direct air cooled or is it using a heat sink system?

It‘s simply aircooled, nothing fancy.

Next week it will try to reset the parameters and se if I gan get her to move And see if I can breathe some more life into the monitor. I will prepare the LinuxCNC retrofit in case the monitor dies on me. Cause I am not willing to pay 600€ or more for an replacement.

If the monitor is dark an old tip is if you gently tap the neck of the tube near the heater this will knock a bit of crap of the cathode This has to be done with the monitor on ie heater on.. At your own risk of course

@Clive,
You had to go there ...
On the back of the CRT there is a detachable board, find the two pins that power the heater inside the tube, cut those lines then take a long piece of whatever thin isolated wire and wind it twice around the ferite part of the high voltage transformer and solder the ends to those two pins on the tube side.
That will bring it back nicely, but it will not last long.

Thanks for the tips, I think there are also ways to tinker with the high voltage part. But all is just buying time. And There is a quite good visible ghost screen.
I think I will start a linuxcnc conversion at some point.
But I would prefer to be able to use the mitt for half a year without any changes, to get her to know a bit. Maybe export some cycles and see what I would change. And the 1000mm x travel will be fun.

I can't read any of the date codes on the compts but the electronics look very 1980s vintage - are they analogue (DC brushed motors)?. Whether or not it can be persuaded to work as it stands, the electronics will be difficult to repair or replace if anything fails. The more time you devote to it in its current state, the more you will lose when it fails.

You are surely going to be doing a replacement with modern digital drives sooner than later. With today's toolpaths and controls, it will fly along in a way the original manufacturer could never have imagined. Looks like a nice machine and I assume it was built as a CNC machine in the factory?
