I start off with measuring the cup and perimeter and the the height of the cup and draw a box with the vector tool. This is a reference point to begin with. For this cup I did the bottom portion as one area and the top portion as another. I loaded an older file onto another tab and then copied and pasted the parts of the file I wanted on this cup. lined them up with in the box I created. 

First I remove the handle and bend the tabs so they do not hit the laser head while it is moving. install the cup on the RA2 tool and level it. Once it is level I use a erasable marker to mark my starting point on the bottom of the cup. Frame the cup and adjust as needed to fill the area desired. Once this is completed I double check my settings and make sure nothing has changed and start the process on the cup.

Once the cup is done I remove it from the machine and take it to a sink and clean it with a magic eraser. I have found this works the best for cleaning the cups afterwords.  straightened the mounting tabs on the cup and reinstalled the handle.
