Alright guys, I'm baffled. My machine is a 2011 VF-2 with probes.

Yesterday I was running a program that I always run, and I noticed a bit of an anomaly in appearance. My ballnose that was running surfacing toolpaths was cutting too deep it seemed, which is odd because I just measured all the tools before this part. So I stopped the program and started remeasuring all the tools. Most all of them measured shorter than when I measured them before the program, some as much as .015" shorter. The ballnose was the closest to its original measurement which is why it was cutting too deep. I packed it in for the night, came down tonight, and first thing, warmed up the machine and measured all the tools again. All of them measured shorter than when I left last night, some were only off .0003", while some were off .0125". At this point, I can't make sense of it.

The Haas service tech was here yesterday before I started running to check out an odd spindle noise (sort of like whipping wind or a plugged up shop vac) that I was getting at 7500rpm and above (10k spindle). He couldn't nail down any explanation, but he did find that the spindle didn't seem to be getting enough lube. This spindle has 400 hours on it and has never been crashed. It just doesn't sound right to me.

Any insight guys?
