Wifi Module keeps turning off and board wiping config.g file

  • Brand new board with config file from online configurator.

    Went through the guide and setup my wifi. Then went on my browser to boards page and started looking around(not changing anything). Suddenly the wifi was disconnected and the blue light on the board was off. Never came back not even after killing the power and on terminal by sending the screen command I would only receive "no PTY".

    After pressing the erase button and installing the firmware again everything looked fine except navigating to system tap which would give me a disconnect and loose the wifi again. Now in terminal i could send a "M552 S1" and reactivate wifi without having to kill power on the board.

    Next step connecting two motors, x and y, and testing the rotation of them. Cause I wanted to change the rotation went again into config.g and changed the S0 to S1. Board reseted fine and motors run the correct direction. During their run I lost the wifi again and after sending M552 S1 and going online I realised that config.g file is missing and my motors are going the wrong way again and joggering. Somewhere there I lost the wifi once more.

    After the erase of my board and bringing it back to life I managed to get a diagnosis test but it was the first ever run without motors or any changes.

    If the blue LED on the board (not the one on the WiFi module) was off, that means that VIN power was not present. That means either you have a bad connection in your power wiring, or something was shorting out or overloading the power supply. The first thing to check is that the VIN terminal block screws are tight. Also check that the underside of the Duet isn't shorting against anything metallic.

  • Sorry I meant the Blue one on the wifi module.

    I have no idea what's going on but I did a second erase and set up my wifi with M589 S"ccc" P"ccc" Inn.nn.nn.nn Cnn and seems to work without getting any disconnections.

    Can you see anything strange on my diagnosis report?

  • @dc42 Ok just found something weird.

    Safari (Mac) won't open the page every time were firefox will. When safari returns "page not found" firefox works like a charm

    Your WiFi signal strength is on the low side at -72dBm, and your WiFi server firmware is a release candidate version (1.21RC4), not the 1.21 release. Otherwise your diagnostic report looks OK to me.
