So I purchased this machined a couple of months ago:

It is a Raycus laser engraver 50W in a cabinet.

I set it up all good, been cutting for a few days with no issue. Suddenly I start getting messages that the USB device drivers are not installed, Win automatically detects the drivers and no problem there but it was starting to get annoying. Anyways one day while cutting it suddenly stops and the same message comes up but this time it does not recognize the USB device. Uninstaled the device. Win detects it, but it no longer list the device but without the relevant driver. It now list it as an unknown device. When trying to update the driver, it does not do it either.

I believe it is probably the control board that crapped out. Manufacturer has magically disappeared, refusing to answer my DMs or e-mails. Before I make a very expensive mistake of purchasing a new board (which I don't know when it will crap out again)..... any advise to confirm this is the case?
