Z tilt goin NUTS with beacon

Hello, V-Core 3.1 500 Toolhead Beta 2 with latest Beacon Revision added This has weirdly happened to me twice tonight. While tilt adjusting my printer just decides to go crazy and move z on one stepper by a 180+. No idea why this is happening but thankfully I've been able to catch it. Before it happens I'll get a "Empty clusters found" error, so I cancel the print, start it again, and then this.....Any ideas?

Wow That's insane, i have never seen that before Something must be going on with the z_tilt math. the measurements are almost dead on. 1.949 to 1.957 that's less than 0.01. Then it goes nuts for some reason. Wonder if it's some under/overflow issue. Not sure if related to beacon. Could be.. Twice in one night... hmm.. Curious.
