Big CNC having calibration issue - yellow tag

The bit CNC is showing signs of slight calibration problems. It was noticed that the dog holes were slightly oval shaped, and a test circle also came out slightly oval. The machine is running, and if you don’t need high precision, it might be fine. But extra testing might be called for at this time

@JOSEGAYTAN - you seem the only person currently on the schedule, so wanted to make sure you saw this
