Why is my T2 Tumbler making a grinding sound?

Twister T2 Troubleshooting

Inspect the tumbler for any visible damage or obstructions on the machine. If none are visible make sure that the bedknife is properly adjusted and in contact with the helix blade. If the bedknife is not in contact with the helix blade it can contact the tumbler. Please see our video on how to properly adjust the bedknife here.
