      got that same Problem like @alexdotz in 2018.

      alexdotzalexdotz 19 Jul 2018, 03:50
      I recently got a duet WiFi, had it up and running, and printed a few hundred hours on it, and then it just stopped letting me connect. My friend in computer science helped me try to figure it out and we determined that the WiFi module just wouldn’t turn on when the board would start up, so we couldn’t connect with the web interface. Though the commend line we can manually start the WiFi module, but this obviously isn’t an ideal situation to have to turn it on every time the printer gets turned off. I would really apply any help on getting this solved so I can go back to flipping the power switch and being up and running right away.

      Thanks,
      Alex

      My Wifi Modul works with usb but not without.

      Thanks for help.

        1. Are you certain that you have a M552 S1 command in config.g to turn on WiFi, and you don't have a M552 S0 command later in config.g?

        2. Make sure that you don't have any M587, M588 or M589 commands in config.g.

        3. You could try adding a delay command at the end of config,g, for example G4 P1000.

              That's odd, because the WiFi module uses the same 3.3V supply as the processor. Perhaps the 5V rail voltage is low when you don't provide USB power, and that is causing the 3.3V rail to be low too. Are you using the internal 5V regulator to produce 5V, or are you using the external 5V input?

                    Can you measure the voltage between the 3.3V pin and the ground pin of one of the endstop connectors, with and without USB connected?

                        Thats it. I forgot a jumper to set on the board. I will uploadt a picture later for anybody who had the same problem.

                        thanks
