AdeV:
Well, I can add my own tale of woe now.... after a happy 10+ hours of machining away, I am sufficiently confident I am not standing over the machine, so I'm the other side of the room when "Bang!" - no problem, just bust a cutter. So I go over, and sure enough the cutter's failed (not sure why, it was cutting as sweetly as you like). So I stop the machine, make a note of the program step, so i can restart in a civilised place instead of having to repeat hours of work, and for some reason I can't reset the controller to raise the spindle, it won't come out of "e-stop".

Reset machine. "DC 24v not present". Ubuggre. Machine = kauput.

I can turn everything on, the controller gets to sampling the 24v DC line & finds it dead, I can even turn the spindle brake on & off, and activate all the motor drives, but the controller of course won't send any signals. Ar­se.

The manual suggests testing the 24v regulator circuit, what it doesn't leave any hints about is what to do if it isn't being fed any juice....

awemawson:
It's a long time since I was in an Interact cabinet, but I seem to remember that one of the two 24v supplies is just a little regulator board. Top left hand side if I remember correctly.

John Stevenson:
I had a couple of 24v RS 'brick' type supplies go down in quick succession for no apparent reason, both were S/H so that may had had something to do with it.
Swapped to a DIN rail mounted one, again S/H [ got shed loads of crap goodies ] and been good to go for a couple of years now.
