This probably isn't the right place to post this, but I have to vent somewhere. I went to look at a fairly recent used machine, a Thermwood CS45 5x10 CNC router with C axis. 4 years old. Nice machine, 150k or so new. Guy says he never really got the hang of it and closed up his shop. Broker says a toolchanger pocket got damaged in shipping, which seems odd, but I'll play along. It's in Atlanta, so a flight and a whole day to go see it. They're asking 99k which is too much and I have them down to 92k, which is worth the trip if the machine is as cherry as I'm being told.
Well, it turns out the tool changer pocket got damaged by crashing another tool on top of it, which bent parts. Not great for a ceramic bearing spindle, plus he never bothered to fix it, which says a lot. I tell him to fire the spindle up. Can't seem to remember how, calls tech support. While he's doing that, I'm poking and prodding at the machine like you do. The machine has an automatic oiling system for the linear rails and the ball screws etc. Which, of course, is bone dry, other than a bit below the pickup. The lines... bone dry. Eventually he figured out how to turn the spindle on (which sounds fine) and notices me poking at the oiler. He tells me, rather cleverly
"Yeah, after about a year it ran out of oil, and they wanted like a hundred bucks for oil so I disconnected it. But don't worry, I sprayed it with WD40 every week!"
