3.3 to 3.4 on Duet2Ethernet DWC Reconnecting/crashing

[clegg78]

I recently upgraded from 3.3 to 3.4 on my Duet2Ethernet (with Duex)

First thing I noticed is the MAC address for the machine changed, my DHCP IP for it went somewhere else, I found the new MAC and got the right IP assigned. This is the first time I've seen such a behavior from an upgrade, this normal? (This was resolved below)

Second, I am seeing a rash of reconnections/disconnections/connection issues when working with DWC since the upgrade. During a print it will especially disconnect me and reconnect me. I am using Edge (chromium) on Win 11, and on my iPhone 13Pro with Safari, both disconnect/reconnect rapidly. Nothing changed with the network wiring or configuration of the Printer. This printer specifically runs most days and on 3.3 was flawless.

Here is an image during a run. I'll post 122 during a run to show the diag.

[Duet 3 MB6HC in standalone mode] [Duet 3 Mini Ethernet in standalone mode] The default MAC address will change in this release. This means that your router is likely to assign it a different IP address from the previous one. If you have a DHCP address reservation for the Duet configured in your router, you will need to update it for the new MAC address.

The change log indicates that it would apply to the Duet 3, but perhaps it also effects the Duet2. I'll try to confirm.

[Phaedrux]

How did you update to 3.4? Did you upload the full zip file? Is DWC also updated?

[clegg78]

@phaedrux Yeah full zip file upload. I am tempted to try it again. And thanks for the note on the MAC change, I kind of skipped over the Duet 3 notes since this is a 2. DWC looks like its updated, looks different and says its 3.4 so I am guessing it is is updated.

You can see in the log above the "Operation failed (Reason: Service Unavailable)" is noted, that is what I have been seeing.

[Phaedrux]

@clegg78 said in 3.3 to 3.4 on Duet2Ethernet MAC Change? DWC issues?:

"Operation failed (Reason: Service Unavailable)"

Can you share your config.g and the results of M98 P"config.g" please?

Can you try with logging disabled? It can be quite resource intensive.

@clegg78 said in 3.3 to 3.4 on Duet2Ethernet MAC Change? DWC issues?:

MCU temperature: min 27.3, current 45.1, max 45.9

Is your board actively cooled?

[clegg78]

@phaedrux Sorry I thought I replied - yes the board is actively cooled, it has a air channel with constant airflow (and thermostatically controlled fans that keep the MCU from going above 45C or so. )

I can disable the eventlog and try, not much goes in there other than the start/stop of the prints it seems.

Everything on this printer was relatively error free until 3.4.0 upgrade caused this pretty chaotic DWC stability issue. I've noticed it from multiple PCs and sometimes DWC wont even come up on mobile devices for some weird reason.

[clegg78]

Update on some testing @Phaedrux @dc42

I disabled both my filament sensors for some testing (Duet Rotating magnet sensors v1.7). 2x of them.

If I enable either of them, DWC constantly reconnects. if I enable both, it gets crazy.

If both are disabled the DWC instance is stable. You can see the sequence here, the system is stable, I enable one of the sensors, and DWC starts dropping and reconnecting.

My Tool 0 sensor: M591 D0 P3 C"e1_stop" S1 R40:140 L26 E60

My Tool 1 sensor: M591 D1 P3 C"connlcd.enca" S1 R40:140 L26 E60

This is crazy repeatable as well.

[Phaedrux]

Interesting. Would you be able to downgrade to 3.3 and see if the behaviour is definitely isolated to 3.4?

[clegg78]

@phaedrux I am in the middle of a large set of production runs on the machine and I am not sure I have my 3.3 config saved (I should, but I need to find it) if I can get a gap I will test, but I had none of these issues before upgrading.

[dc42]

@clegg78 it could be that the object model has grown too large for the output buffers. Please provide your config.g file so that I can investigate this.
