3.5.0 RC3 cannot connect to DWC

[KP0005]

DWC dooes not load on a Kindle

[KP0005]

Works on chrome on linux but not Vivaldi

[KP0005]

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

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

[KP0005]

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

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