Free CNC Info Packet at bit.ly/2mWwi3m - Laser Engraving Mug on EC Laser In this quick cut we customized a mug for an employee who is a fan of the show Twin Peaks. We used a rotary turner on the SmartShop® EC Laser to get a proper engraving on the mug. The employee then took the mug home and painted in the black that you can see in the final shots.
