Tested with Chrome, no disconnection at all

Is there any way to fix or replace the wifi module if it is failing?

Yes it can be replaced if you're handy with soldering. I believe a hot air rework station is recommended.

Check this thread out. He was able to remove it with just a soldering iron.

[mike5490]

Okay, thank you.

Is there anything else that could potentially be the problem, as I'd only like to start desoldering parts from the board as a last option or is the wifi chip the most likely cause?

[Phaedrux]

Well we've ruled out the firmware, and your signal strength is good, you've tried another router.

Unless there is some other source of interference in the area you can identify and eliminate.

You could try switching to another wifi channel.

You can try and provide an M122 from when it's disconnected.

[mike5490]

Trying multiple different wifi channels didn't seem to have any effect on it.

This is my results from M122 after it disconnects

Was that while disconnected or after reconnection?

[mike5490]

That was after it had reconnected. Is it possible to get a readout while it’s disconnected?

Yes, via USB.

[mike5490]

I tried to get a M122 while it's disconnected but have been unable to

Every time it disconnects the USB connection to my computer also disconnects, similar to as if I was unplugging the USB cable

[mike5490]

After a bit more troubleshooting I've determined that the printer behaves as if I sent a M999 command but it occurs at random times

this always happen when the board is reset.

running M122 first thing after connecting to the board again would be helpful. is there anything that could short against the reset pins or trigger the reset switch on the board? pictures and M122 might provide some insight.

[mike5490]

The results from M122 immediately after it reconnects are provided above in a previous post. There's nothing that could be pressing against the reset button.

This is how the board is currently wired

[dc42]

Please upgrade to 3.1.0 release firmware and if the problem continues, post another M122 report taken immediately after it reconnects.

The ground wire between your Duet and DueX5 isn't done according to our wiring instructions. This might be part of the problem, OTOH the wires between them and the DueX5 are short, which will help to mitigate the incorrect wiring.

as in

?

Unless the firmware is wrong it would suggest you had a power glitch? In any case, what he said

[mike5490]

Thank you for pointing out the wiring issue. Unfortunately after fixing that and upgrading to firmware 3.1.0 I am still having the same problem.

This is my M122 immediately after the printer reconnects.

@mike5490 Can you please share your config.g? How can you reproduce it? If it happens while printing a certain file or while running a certain macro, please share that, too.

[mike5490]

I don't know how to reproduce the problem as it's intermittent and I haven't been able to find a cause yet. I haven't bothered to run any macros or prints yet as I'm trying to get the printer working correctly first.

Here's my current config.g file

Please try again with the 3.1.1 release, which we hope to make available later today.

[mike5490]

@dc42 I installed the internal build for 3.1.1 -18b8 last night and am still having the same disconnect problems.

[dc42]

Please try the official 3.1.1 release.
