Help! DWC Disconnects and Drops after extensive troubleshooting

Danal

Strictly for troubleshooting, have you considered putting the printer in Access Point mode?

Then testing with a phone or tablet or laptop a few feet from the printer, then further away, etc. Then with the mobile device in the next room... then near the router... etc, etc. A demonstrable "map" of connectivity.

This type of testing removes your home network from the picture. Once you've verified that the DWC is (or is not!!!) stable from various distances when the link is direct printer<>device, you can go back to making it reliable on your home network, with some data points in your mind about the printer's basic physical capability to wirelessly reach various places in your home.

I attempted access point mode already with no success. It's not a matter of physical distance for sure, as my printer is literally adjacent to my wifi modem with no barriers between them.

Danal

Edit: Wrong thread. What I meant to say here:

If AP mode is unstable, it is guaranteed that everything else will be unstable. Go back to AP mode, thus eliminating a whole bunch of variables, and debug from there.

Probably minor, but you have M587 in your config.g. You should comment this out or delete. From the Gcode dictionary:

Important! Do not use M587 within config.g. As well as being a security hazard, writing the access point parameters to WiFi chip every time you start the Duet may eventually wear out the flash memory. Also, the wifi module does not get enabled until the end of running config.g. It is better to use a macro to send M587 (source: https://forum.duet3d.com/post/42798)

Well...it has officially quit working completely...

When I try to access the DWC I'm met with a blank white screen that never populates...

@dc42 would doing a hard firmware reset be a possible solution?

Does it time out?

Can you ping it?

@droftarts

I don't have a filament sensor or panel due fitted.

It's strange that that is what it's reporting considering the last reset was done by me via M112.

Please run another M122 report after the network has disconnected, without doing any emergency stops. I want to see if the "Heat task stuck" report is a recurring thing, or if it is a consequence of the emergency stop.

alexd607

@Danal

It does not timeout, and it still pings without any loss.

@dc42

I was able to get momentarily connected and run M122 right after power-up, here's the result:

If it pings, you have a solid network connection and we can quit looking at the basic networking stuff.

Were it me, I'd rebuild the www directory on the SD card.

And/or, as a test, you can put your own "test.html" page on the www directory, and test via:

http://(ip of printer)/test.html

I've tried rebuilding the www folder already, as well as every other folder. I've tried rolling back to older firmware, and I've tried reloading the most recent full releases. All had the same result, no luck.

Danal

If it pings, you can get packets to/from. That means WiFi is working, fundamental packet routing, etc. If it does not show a web page, that means something is broken in the HTTP layer, or web server, or content.

To help decide which try putting:

<html>
<head>
<title>Test Title</title>
</head>
<body>
Test Body
</body>
</html>

In /www/test.html

Then use a browser to attempt to load http://(ip of printer)/test.html

What happens?

alexd607

@Danal

I'll give this a try this evening and report back.

Please try firmware 2.05RC2 in case this issue is related to a USB output issue in previous releases.

@dc42

Tried upgrading to firmware 2.05RC2. No change.
