Recently had to pull the table off my machine for service work to the rails and trucks. In doing so I removed the OTS from the table to prevent damage. Machine is back together, all aligned, squared, and working properly in that regard. For reference, this is a 2011 VF3SSYT classic controller.
Reinstalled the OTS to the table today in the exact same position, and ran the calibration procedures as I normally have in the past using a precision ground calibration bar in the spindle(Maritool). After doing so I pulled up a tool that had been in the machine and previously calibrated prior to the OTS removal and ran the probing cycle as a test. The cycle ran as it should, however the OTS is calculating the tool diameter(or radius in this case)incorrectly. Tool measured out length wise within .0001" from previous measurement, but the radius was WAY off. The tool is a 1/4" diameter 4 flute endmill, and had a previous radius measurement of .1247" The OTS repeatedly records it now at .0327-.0328" instead. We're not talking a few tenths or even thousandths. I have run the calibration process a handful of times today and nothing changes. I pulled the batteries out and reinstalled them today in the OTS as well and did not touch the stylus during the startup procedure.
What else should I be looking at here? Could something have changed without my knowledge while the probe was off the table? I had the probe stored upright tucked into the corner of the cabinet behind the controller, so it wasn't getting bumped around in a box or drawer somewhere. I am not that familiar with the actual macro(s) itself, nor the parameter settings on the machine so is there a specific data set that I should be looking at to see if something changed? It just has me stumped as the way I see it if the OTS was damaged it wouldn't be reading the Z axis length correctly, but it is.
Anyway, any help would go a long way here because it's either that or calling a tech back here
