*1. Inspect the machine and bed for any debris, especially the ball screw
*2. Ensure that the hose to the compressor is attached to the CNC air-assist connection.
*3. Turn on the air compressor (push red toggle switch backward). Only if necessary, adjust air compressor regulator to provide 60-80 PSI pressure to CNC if it has been changed. The CNC has a second regulator regulator for the air-assist and should already be at 40-45 PSI since no one changes it.
