Slow upload rates and connection errors

[WillGIam]

Hello!

After being totally frustrated I´m trying to find some help in here.

I have 3-4 printers with duet 2 or duet 3. All of them are working fine. Today I finished my newest build and updated everything on the duet. After getting a blank screen, I tried different DWC versions and when updating again I got it running.

The whole file upload is very slow, often I´m getting connection errors and when starting heater auto tuning for example I´m just getting this error:

Connection interrupted, attempting to reconnect...
HTTP request timed out

I tried nearly everything, restartet router, restartet board, scanned the wifis and changed to channel 1 with my router - nothing helped.

Now I´m getting the blank screen again... connection via pronterface works fine...

I hope you can help me.

William

Do you get the same problems when running 3.1.1?

https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/Duet2and3Firmware-3.1.1.zip

The wifi server version in 3.2beta2 is updated (1.24) and you don't mention any firmware versions.

If you upload that complete zip file to the system tab in DWC it should flash everything back for testing.

[WillGIam]

Hey Phaedrux,
Thanks for your reply.

Server FW is 1.24, as you see in my comment. Also you can see, that I was using 3.2-beta3.

Because I´m not able to upload anything on DWC, I have to change the files on SD.

I changed the Duet2CombinedFirmware to the 3.1.1 and the DWC too. -- still blank.

After a while I´m getting the DWC (instead of blank screen) and can do something, but not uploading.

After putting 3.1.1 and DWC on SD I got no system drop down settings, but it seems as I´m now able to upload a firmware file without breakdown. - Lets see what happens.

[Phaedrux]

Can you place this wifi server bin file on the SD card in the /sys folder and then send M997 S1 to flash the module back to 1.23?

I flashed everything back to 3.1.1 and Server to 1.23, but still the same problems.

Could a board erase help?

[WillGIam]

Thats what it looks like most of the time. After a while DWC appears, but very slow with connection breaks.

[Phaedrux]

@WillGIam said in Slow upload rates and connection errors:

Doubtful, since we've already flashed the firmware again.

When you send M997 S1 does the flash process appear to proceed correctly with a percentage complete list?

When you lose connection, does the light on the module go out?

Can you create these macros and use them to clear the saved networks and reset the module with your SSID?

; Clear all wifi networks
;
M291 R"Clear WIFI networks? Y/N" P"Caution. New network must be added." S3 T10

M552 S0			; Disable network module
G4 S5			; wait 5 seconds
M588 S"*"			; Clear all saved wifi networls

M291 R"WIFI networks forgotten." P"You must add a new WIFI network."

; Add default wifi network
;
M291 R"Add default WIFI network? Y/N" P"This will add duetwifi access point." S3 T10

M552 S0			; Disable network module
G4 S5			; wait 5 seconds
M587 S"NETWORKNAME" P"PASSWORD"			; Add duet wifi SSID to remembered networks list
G4 S5			; wait 5 seconds
M552 S1			; reenable wifi module

M291 R"duetwifi SSID added." P"Check console to verify IP address."

IT's easier to use the macros because you can execute them from command line more easily than retyping everything. Just send M98 P"macroname" to run them.

[Phaedrux]

Is this a brand new duet wifi? When and where was it purchased?

Well...

Yes.

When you lose connection, does the light on the module go out?

No. its still on.

will do that now.

thanks a lot.

@WillGIam, are you certain that there isn't another device using that IP address? Try pinging it. Then turn the Duet off and try pinging it again.

Tried to clear all networks and added it again - same problem.
I dont really know when and where this duet was bought...

@dc42 said in Slow upload rates and connection errors:

Yes. When duet is turned off, there is a timeout.

[Phaedrux]

Does the Duet show up in the router interface?

@WillGIam said in Slow upload rates and connection errors:

That would make it difficult to ascertain it's warranty status. If it's within 6 months from an authorized reseller you would be covered.

[WillGIam]

@Phaedrux Yes, it shew up in the router interface.

Yes, I´m not covered I think. I dont think its a hardware issue - I tried nearly everything now.

[Phaedrux]

Only other thing I can think of is to try a new SD card in case it's having problems reading the file system.
