Begin by removing the engraving table from your system and insert the rotary device. To do this, lower the table and remove the engraving and/or cutting table. Insert the Rotary Attachment and plug it into the machine. Turn the machine off and on again to establish the Rotary's position.
Place the bottle on the rotary device and focus the machine. Run the job and you're all set!
