I have recently added a pneumatic valve to control mist coolant. Now my monitor often momentarily blanks when turning coolant off and very occasionally my VistaCNC pendant resets. That sounds like perfect symptoms to install a Tormach "33059 - Electrical Noise Suppression Kit". I am in Canada so delivery won't be for a week or more. From the description and picture on the Tormach site it is simply a RC snubber. Is that all there is to it? If I'm right a 0.1mfd capacitor in series with a 100ohm resistor should do the trick...
