Wi-Fi Module

SMKForum

Board: Duet 2 WiFi
I also have the DueX 0.11

When powered from the PSU, the WiFi module never turns on. I measured the voltage of the +3.3v using the X Stop +3.3v and the Z Stop GND.

I got a perfect 3.3v.

When I power the board with USB, the module is always able to be turned on and is functional.

The difference in voltage is that the USB voltage result is 3.306v.

When using the multi-meter, I left GND before I left the +3.3v pin while powered on from the PSU, and the Wi-Fi was then able to be turned on.

Any ideas on resolving this issue?

@SMKForum that is a very unusual fault. The 3.3V regulator is powered from the 5V rail either way, and if you have 3.3V present on the board then that regulator is working.

Can you try with noting plugged in except for the power supply (including do not plug in the Duex5)

I know you said to remove everything, but I removed the DueX ribbon and the power connectors to the DueX and I removed the PanelDue display that I have from the main board. Powered it up and the Wi-Fi module still couldn’t boot.

@SMKForum is there anything else still connected? Could the back of the board be shorting out against anything where it is mounted? Please post a good picture of the Duet board as it is at the moment.

Do you mean that it turns on without you sending any commands from USB? Or so you need to send M552 S1 to turn it on?

@dc42 In my config.g, I call a program that executes the command M552 S2.

However, since the Wi-Fi module does not turn on, I type any networking related G code into the display and receive no response. I can definitely take a picture of the board and post it tomorrow.

Please provide your config.g file and that macro you call that executes M552 S2. Also please confirm that sending M552 S2 from USB turns the module on and allows you to connect over WiFi.
