Pair Of Neje DK-8-KZ 1000mW Laser Engraver Printer Cutting Engraving Machines

You are bidding on TWO identical laser engravers. The engraver uses two USB ports – one for power and the other for data. I have used them with the manufacturer’s own software (PC) as well as EzGraverUI for the MacOS (open source). I have been using one perfectly without any problem. It works flawlessly.

It cuts and engraves as per manufacturer’s usual parameters. The other has developed some problem with its laser. It used to work properly when I bought it. But now even though the machine goes through the motions, it doesn’t mark or burn or cut at all. It could be a misalignment, or a dirty or defective lens - I simply don't know.

It connects to the computer, communicates with the software, and the laser beam seemingly fires but it doesn't actually engrave. I have tried software on the Mac and PC and neither software reports any problems or errors. So mechanically and electronically it is sound. But it may be a simple tweak of focus, or it may need a new laser diode - I don't have the technical knowledge to fix it. Included: 1 x working laser engraver 1 x non-working laser engraver I had bought them new in late 2016.
