Abstract
A laser engraving machine with a three-point suspension system and an inverted X-Y axis support system wherein the X-axis beam is to and mounted below the Y-axis beams and the Y-axis beams are mounted inwardly of the outer ends of the X-axis beam and are structurally integrated with the machine housing. In addition, a counterweight in the form of a second, independently activatable laser is added to the drive belt to reduce or eliminate vibration during rapid reciprocal movement of the tool during an engraving process.
