Mining units are fully autonomous but need to be calibrated to work efficiently Each mining unit has a calibration score and slowly loses calibration over time if kept unchecked When the calibration score is below 100% the mining unit will produce less ore at 0% it won t produce anything at all To remedy that it must be calibrated
