Figured out why my 5 year old Haas was throwing alarm 167 after 8 hours of hunting
Machine kept dropping out mid cycle with that stupid spindle load alarm. I spent all day Tuesday swapping sensors and checking the VFD only to find a 50 cent O-ring on the coolant line was shot. It was letting just enough coolant mist hit the encoder. Spent 2 hours on forums and another 4 actually working on it. Total waste of a shift for something a dab of silicone wouldve fixed. Has anyone else had a tiny leak cause major phantom issues like that?

I spent a whole afternoon once chasing a bad ground on a CNC lathe turned out to be a half crushed soda can under the panel shorting things out. It's always the cheap stuff that makes you feel like an idiot.

My buddy had a similar thing on his Okuma lathe last year. He was going crazy over a misaligned turret for like 3 days. Turned out his apprentice had dropped a 10mm socket in the chip tray and it was just rattling around hitting the home sensor at random times. Took 2 minutes to find once he finally looked.

It's funny how those little random things always end up being the culprit, isn't it? That's just life though, the most complicated problems usually have the simplest answers staring you right in the face.
