@eddygara If you're experiencing issues with connectivity between your printers that are causing printing problems, you may be wondering if there's a way to operate your machines without needing an internet connection.

One potential solution to consider is using a Duet touch screen to operate your machines. This would allow you to control your printers directly through the touch screen, without needing to connect to a network. By using a touch screen, you can bypass any connectivity issues that you may be experiencing and operate your machines directly, which could potentially help to improve your overall printing experience.

@ardisf said in 3.3 volts LED indicator doesn't lit:

i own a Duet 2 WiFi, i assumed i shortend the "always on" fan.
and right now, 3.3 volt LED indicator in my Duet doesn't lit. it makes motor LED indicator and WiFi LED indicator doesn't work.
is there any way to fix my duet?

Yes, it is possible to fix your Duet 2 WiFi. The first step is to check the power connections and make sure everything is connected properly. If the connections are good, then the next step would be to check the firmware and make sure it is up to date. If the firmware is up to date and the power connections are good, then you should check to see if the main board and other components are working properly. If anything is not functioning correctly, then you should replace the faulty part. Finally, you should check to see if the shortening of the "always on" fan could have caused any damage and if so, replace the damaged parts.
