Here's a project I did using the new Scan N Cut engraver by Chomas Creations. The regular engraving tip available now is awesome for filling in lines like I'm showing on my bulldog engraving.
When you have details like this you have to send the project as a draw file, not a cut file. You will lose all the little lines that make up all the details. I also set the machine to draw and used a pressure of 9 and speed of 5. You can find the new Chomas Creations engraving tip here... engraving tip
Always remember to either use double sided adhesive or painters tape to secure your piece.
I got these acrylic pieces and the LED light bases from Craft Chameleon.
Here is the finished project!
