1st- Set up your Rotary Attachment. I have the rotary pro with the laser to line up laser module to the center of tumbler. 

2nd- wipe down the tumbler to remove any oils or dirt.

3rd- insert tumbler and check for level.

4th- on XCS change from flat process to rotary chuck and insert parameter size.

5th- place cross hairs at edge of clamp (chuck), rotate template along with outside border (make sure to set to ignore). Double check that the design is combined to help with run time. Check your settings. Power-90, speed 400, lpc 200.

6th- I put the corner of border to the cross hair. Then if you have the updated version, click on preview in the top center area. This will give you a nice preview of the tumbler before you engrave.

Do your framing to ensure you like the position. click start and sit back and watch it run. 

Runtime just under 60 minutes.

After machine is stopped, loosen the chuck. I use magic eraser to remove any soot. Then I take La Awesome and spray the engraved area and leave sit in the sink for a few minutes after rubbing the cleaner over the tumbler. Last step use scrubber and warm water to scrub and rinse and dry. 

Enjoy.
