I found it. Probe Offset in MatterControl is NOT the same as running M851. To elaborate: In MatterControl, 0_1646622462971_adb26788-7886-4379-a263-4255efd860d6-tempsnip.png is not the same as 0_1646622534423_5864d9ee-3c54-4d1d-af58-bc0cf11bfc75-tempsnip2.png Ran ->M851 Z-1 in the terminal and was able to run Z-Calibration and Print Level with probe.
