Curious as to what others are doing to keep the fine dust out of your PC and the CNC control boxes. Without a filter on the Avid CNC control boxes, the electronics will coat out with fine dust. I have added a homemade filter to the inlet to try and manage dust incursion. Same with my dedicated desktop PC. Got it wrapped in one of those PC non-woven breathable dust covers. Works so-so. What are others doing?
