@T3P3Tony by everything works I mean when it’s plugged in all the leds come on and when the power supple is on all the fans and the bltouch come on. I have no way of controlling it. Device manager doesn’t see it. No program sees it. Not yat, not Bossa, not SAM-BA, not anything. At this point I have exhausted all options. I have tried different usb cables, ports, computers, softwares, the works. I am running windows 10. Is there a warranty or something on it. I got it in December from I believe matterhackers.

@t3p3tony No detection of it at all in any form. Tried with different software, USB ports, usb cables, and computers. When I power the printer on everything works but I can’t access web control because I don’t know the ip because I can acces it on the computer

1. When you says "everything works", what do you mean by "everything"? Does the printer work, and if so, how are you controlling it? (from an LCD perhaps? What sort?)

2. Do your PCs run Windows, Linux, or MacOS? If it's Windows:

• Open Device Manager, expand "Ports - COM & LPT", and see if anything changes when you connect or disconnect the Duet. Also look out for an "Unknown device" showing up in Device Manager.
• Try a different USB port, and/or reboot Windows. Windows sometimes gets into a state in which it is unable to use a particular USB port.

3. Which type of Duet is it; and is it a genuine UK-manufactured one?

@t3p3tony I tried 5

@T3P3Tony I have poured through all of the fallback procedures and all of them either didn’t apply or didn’t work. All the fans and lights work but no external device will recognize it.

@t3p3tony how do i reinstall if i cant acces web control?

as the title suggests when i plug in the board all the lights go on but YATand my computer as a whole doesnt acknowledge the duets existance. it has been working fine for months and i have restatrted and replugged everyhing and have reinstalled the drivers
