    rubycons baked dry in 8 years flat

    not 1 of these rubycons are good.
    all very high esr.
    its what happens when you cram a bunch of electronics in a box with no ventilation.
    we see a ton of these.
    caps are just a minor issue with these.everything else gets cooked too.
    7-8 years of 24/7 and these units need a total rebuild.

    YK series are basic general purpose caps. They should be using something high endurance and 105C.

    But granted the caps weren't the only thing bad.

      Our school's cnc machine has a acu-rite almost like that one. Has a 166mhz MIPS processor and 6 megs of ram, is that what that is? Probalby the same everything except the outside shell and the keypads in the front.

          Actually, if i remember right, our school's has a LCD, not a CRT, and the processor is up against the back of the case, and the heatsink sticks out of the case and vents out into the open.

            the heatsink on the rear is the power supply.
            a few newer ones have lcd's
            and no i dont mod the case for ventilation.
            its a waste anyway as the operator cant be bothered to clean fan filters .

              kc8adu; you could always have a fan inside that unit
              Air blowing around is always better than air standing still
              Some of our (IMO) better CNC machines just move the air around in the electrical cabinets, they don't let any new air in. And therefore they stay clean and nice inside!
              (Well, the best ones have a watercooling radiator inside the eletrical cabinet but oh well, hope they never spring a leak lol!)
