So I finally found out why I was having problem tripping my spindle when I would use air to clean off my table. My air compressor is located far from my CNC. On Monday my spindle tripped just as it was grabbing a tool and it would not reach pressure. The air pressure at my compressor was fine, but I found that my one filter had clogged to the point that the pressure had dropped too low on the outflow side. I replaced the filter and all is running again. Between the compressor and my spindle I have a desiccant filter and Milton coalescing filter. I added an auto drain to my air compressor about 8months ago, and that made a huge difference to removing water in my line. Looking into things a bit closer now it turns out the desiccant my filter uses is very corrosive to the steel housing, so I need to replace it to avoid rust particulates clogging the filter downstream. I know commercial shops use freeze dryers and I likely should bite the bullet and put one in. I was trying to avoid spending another $1,500 (no harbor freight option here), but now that I have to replace that desiccant filter I am thinking it might be time to stop the slow bleeding of funds. My question (finally) is what are most using? I likely put 300 - 500hrs on my machine in 2years.
Thanks
