In that case, it looks like a configuration-dependent firmware bug and what I ideally need is a Wireshark trace (the .pcap file) of a connection attempt. If you find that too difficult, then if you post your config.g file I can try to reproduce it.

JuL · 29 Aug 2018, 19:03

I've got a .pcap file for you. Unfortunetly is to big to upload. Can you give me your mail address for it (or an altenative)?

Wait, I think i've just find what's wrong. There was an error in the config.g . SSID name was different between M587 and M552
I'll try after my print and tell you

This is my config.g

Please put the .pcap file on Dropbox or another file sharing site and post the link to it here. Alternatively, look for the http 200 OK response where Wireshark reports that the response format is JSON but instead of letting you expand the json object is reports "Line based text data". That will be the faulty response. So right click on that, select copy as text to get the full data, and paste that here.

Having a different SSID name in M552 and M587 should just result in failure to connect to your router. The SSID is not passed to DWC so I don't think that is triggering the problem.

btw the M307 command in config.g will override any M307 command for the same heater in config-override.g that was obtained from turning the heater. We normally put the M501 command near the end of config,g so that it overrides values in config.g as the name suggests.

Let me know if this is what you want:

@jul, that's the truncated version, which is too short. If you right click on it you should get a number of options including "Copy... Bytes as printable text". Choose that one, then paste it in your post.

@jul said in Disconnected when M291:

In theory that's what I need, however there is no error at column 188 in that line. So either:

The line you copied isn't the one with the error. Did it say "Line based text data" or similar?
The error no longer occurs at column 188. Did you upgrade the firmware? if so the column number may have changed. Please check the DWC error message again.

EDIT: I just spotted an error at column 224. Investigating.

JuL · 30 Aug 2018, 19:17

Yes it say "Line based...". I have another but just with '/n /n' so i didn't think was relevant.
I didn't upgrade since T3P3Tony ask to go with non Beta version. Also, I don't have any error message since this upgrade, I can just see there is deconnection on the gcode console

dc42 · 30 Aug 2018, 20:04

Please can you test whether the new firmware binary at https://www.dropbox.com/s/fyvibzm0zl92hiy/Duet2CombinedFirmware.bin?dl=0 solves the problem. Caution: this is a beta, so babysit it.

JuL · 30 Aug 2018, 20:08

I'll try it ASAP, I hope Sunday

dc42 · 30 Aug 2018, 20:11

OK, that's probably too late for me to do anything else if the fix doesn't work, because a release deadline is approaching.

The bug I found occurs if there are both a beep and a message box pending at the same time. The M291 command causes the message box to be pending. I guess you have another GCode command nearby to generate a beep.

JuL · 30 Aug 2018, 20:20

I've got a bip command at my start script, but I can try without it tomorrow for my next urgent print

I just tried to launch an already made gcode without the BIP command (remove by hand)
TADA !!! No more disconnection
