Open one of the EPS files in Corel Draw and get it lined up with the art board. You will do this for each file.
Step 12: Print Settings for the Laser
Open the print box and click on preferences to open the settings for the laser.
Step 13: Set the Power and Speed Settings
Set the power and speed settings needed for the laser you are working with. We used 100% power, 10% speed, and 300 ppi to cut the wood, and 100% power, 84% speed, and 500 ppi to engrave the wood.
Step 14: Focus the Laser
Follow the necessary steps for focusing the laser you will be using to cut out the pieces.
Step 15: Cut the Pieces of R2D2
Press play on the laser to start cutting the first sheet of wood. Repeat for the necessary number of sheets of wood.
Step 16: Organize Pieces
Once all of the pieces are cut out, organize them by layer.
Step 17: Ventilation and Space
Make sure you have proper ventilation and space to work.
Step 18: Assemble R2D2
Using the instructions from AutoDesk 123D Make start assembling R2D2 using spray adhesive or other glue.
Step 19: Let Glue Dry
Allow glue time to dry, using clamps of other methods to hold the slices in place while the glue dries.
Step 20: Enjoy!
Enjoy your awesome R2D2!!
