3.5.0 RC3 cannot connect to DWC

KP0005

More testing:
DWC is mangled in safari on macos
Doesn't load at all in Chrome on mac os

KP0005

The issue has happened a few times before (including on stable builds months ago), but always resolved itself after a few minutes, hours or days.

I'm considering going to Klipper instead, since it's seriously impacting use.

@KP0005 can you run some diagnostics on the SD card? see https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card

I'll test rc3 on my Maestro when I get the chance.

Mangled DWC opened in OrcaSlicer. This is exactly how it displays on Mac and occasionally on my system

Screenshots obtained using Edge inside the windows vm

I do not think it's the SD card

Current theories are either a software issue, a hardware issue (I have accidentally shorted the mainboard for a few miliseconds with a fallen screw several years ago, long before this started happening) or some interaction with my network setup.

Due to being unable to run ethernet cables to this floor, I use an old wifi router with DD-WRT as a bridge. I have used it as such for several years now, and DWC did work.

Keeps happening for me too some times. Restarting the printer usually works, but it's for sure another issue that needs attention.

Like now, if i try to connect to the printer using my phone(chrome on android) it can't connect and gives the error "ERR_ADDRESS_UNREACHABLE".

Update:

reverting BOTH DWC and RRF to RC2 fixes the issue

KP0005

@KP0005 reverting DWC but NOT RRF does not fix the issue

KP0005

so could it possibly be an RRF bug instead? @dc42

KP0005

DWC RC2 + RRF RC2: works
DWC RC3 + RRF RC2: works (but gives incompatibility warning)
DWC RC3 + RRF RC3: does not work
DWC RC2 + RRF RC3: does not work

@KP0005 there have been a lot of ethernet network changes on the duet 2 and maestro between RC2 and RC3 so it'll be linked to that.
Stick to RC2 for the moment until it's investigated

Exerqtor

@jay_s_uk It looks like it might be effecting Duet 3 Mini as well for what that's worth.

@Exerqtor Are you saying you did not have that "ERR_ADDRESS_UNREACHABLE". on previous versions of RRF?

@gloomyandy said in 3.5.0 RC3 cannot connect to DWC:

@Exerqtor Are you saying you did not have that "ERR_ADDRESS_UNREACHABLE". on previous versions of RRF?

Never had it on multible devices before no, I've for sure had issues with RRF not being able to connect to the SSID, but I haven't had lasting connection issues when it's been connected the AP.

Now i see it on the management page of my network, so it's connected. But i can't connect to DWC:

gloomyandy

@Exerqtor Can you still connect to DWC from your computer? Have you been able to connect to your printer from your phone in the past?

Exerqtor

@gloomyandy When the issue is there it's not possible to connect with any of the devices i've tried doinh so with (Windows pc's & android phones).

And yes, "before" i was able to connect with phones etc. most of the times. Some times it was a little bit picky with letting devices connect, but after a refresh or two it usually let me in.

Now i have to restart the printer (M999 through PanelDue) to connect with anything once it's acting up.

@KP0005 I've updated my Maestro to rc3, and I'm having some problems with it. Mostly it works, but I only connect from one PC, via one browser tab. However, I can't 'refresh' the list of jobs without getting an error message:

Failed to get file list
Network error

and the list stays blank when I know there are files on there. Reverting to RRF rc.2 (with DWC rc.3) fixes this.

We currently think this is due to the reduction of network responders in rc.3 for Duet 2 boards, though I don't think I've seen any reports of problems from Duet 2 WiFi/Ethernet users:
https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x-RC#reprapfirmware-350-rc3-changes-since-rc2

[Duet 2] [Duet Maestro] The number of HTTP responders has been reduced from 4 to 3. This should not matter unless you have HTTP connections to the Duet open on several PCs or in several browser tabs, or you upload files from two or more PCs or browser tabs concurrently.

@Exerqtor The Mini 5+ issue is different, and related to WiFi; the Duet 2 Maestro is Ethernet. I also have occasional disconnections on Mini 5+ WiFi, so I'm trying to capture these with logging so we can investigate. I have a macro on the Paneldue that turns off Wifi (M552 S-1) waits for 5 seconds, then turns it back on (M552 S1), which has worked fine to kick it back in to life. It's always happened when I'm actively doing something on the machine, not when running jobs.

There are other threads relating to this issue; please lets keep this one for the Maestro issue.
