    Laser engraver/cutter

    My engraver got halfway through an image, then the laser power dropped significantly. I'm using the supplied software and hardware, including their power adapter. The table and laser head move properly, the low-power beam is on to show the image area boundaries, and when it should be burning, the laser is simply too weak. Though it is significantly brighter than the low-power beam, it isn't the eye-searing intensity that it was before it failed. The problem isn't the wall-wart power supply that came with the engraver, either: I see the same behavior with an Apple iPad power supply capable of supplying 2.4 A at 5 V DC. A USB power supply monitor shows 5.2 V from the supply, with a draw of 0.48 A max while the engraver should be burning. This means the laser is drawing just over 250 milli...see more »My engraver got halfway through an image, then the laser power dropped significantly.

This means the laser is drawing just over 250 milliwatts max (discounting power to the other electronics and to the motors).Either the laser is damaged or the power control circuitry on the engraver has failed; I suspect the latter. My wife discarded the packaging, including the order number. Can anyone supply an order number for one of these, so that I can file a ticket with GearBest?
