Duet 2 WIFI

Hi all, I've had a bit of a hiatus for 2 years and I'm finally back into this passion project of my 3d printer. I got a new ISP and now when my printer is in my basement, I get this AJAX error after 30-45 seconds, and can not reconnect unless I power cycle the machine. It does not matter if the machine is moving or not, and it will never reconnect. The connection is completely stable However when the printer is in my office (first floor) I can connect and use it no problem. I have done 3 test prints with no issues. 2 years ago, the printer was in the basement and never had an issue, which is why I'm inclined to believe it has something to do with the ISP change.

I am completely befuddled. Some useful information(?) is: like I mentioned, I got a new ISP (Century link/quantum fiber) which came with a 2 pod mesh network wifi.

I am running an old board, version 1.0, and old firmware version 1.19.2.

Anyways, here's an M122 that I was able to send before the disconnect:

RepRapFirmware for Duet WiFi version 1.19.2 running on Duet WiFi 1.0

RepRapFirmware v1 hasn't been supported for ages. I suggest you upgrade at least to RepRapFirmware v2 or even better to v3. See https://docs.duet3d.com/en/User_manual/RepRapFirmware/Updating_firmware

[Mklein23]

@chrishamm I figured that may be my best way forward. I've been watching firmware installation tutorials all morning.

Seems like the best bet to jump up from ver 1 to ver 3.1 is to install it using Bossa.

Will new firmware require new system files? Config.g, homeall,g, etc?

[droftarts]

@Mklein23 3.4.6 is the current release, not 3.1, so update to that version. You can do that directly with Bossa. Yes, you'll need new configuration files, but don't forget to backup your current SD card to be able to refer to your old config. You can upgrade via DWC rather than Bossa:

To update to 3.x, if you still have access to DWC, upload these zip files one at a time in the system tab. Don't extract them first. Reboot after each. Use M115 in the gcode console to verify the firmware has been applied.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/Duet2and3Firmware-3.4.6.zip
You'll need to generate a fresh config set for RRF3. https://configtool.reprapfirmware.org/
There are notes on migrating between 2.x and 3.x here: https://docs.duet3d.com/User_manual/RepRapFirmware/Migration_RRF2_to_RRF3

Though sometimes it's worth starting with a new SD card to this specification: https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card#specification

@droftarts so I downloaded files you linked, and started with 2.05, duet recognizes it as firmware and prompts me to install it. I click yes, some installing happens, and the wifiserver setup gets almost all the way to the end, then the progress bar disappears, and nothing happens. M112 shows firmware 1.19, and wifi 1.0.

Is there anything I need to check on the board itself?

I'm using the SD card that came with the board. I can dig around for a different one and try that?

This is all Greek to me.

[Phaedrux]

If you still want to do the DWC metho, try updating to 2.0 first.

Or try sending M997 to trigger a firmware flash.

If that fails, BOSSA would be the way to go. You'll need to manually update the DWC files in the WWW folder. If that all works you could upload the 3.4.6 zip file again just to ensure you have all the IAP files, etc ready for the next time you update.

[Mklein23]

@Phaedrux ill give earlier versions a try.

If I go with bossa, do I still need to install firmwares sequentially, or can I go straight to 3.4?

[Mklein23]

@droftarts I'm finally making progess on this, I had to go back and start at 1.2, then step forward one release at a time looking at the change notes to see when the big changes were.

I've had to go
1.19(start) > 1.2 > 1.21 > 2.0 > 2.1 > 2.05 > 3.0

I tried going to 2.05 first but it wouldn't take. I think in 1.2 and 1.21 had wifi server updates that conflicted with the files in 2.05.

Keep on chugging I guess.

[Mklein23]

@droftarts
I got up to firmware version 3.3, WIFI server version 1.26, and web interface version 1.22.3

Now I'm getting an Error:

M997: File 0:/firmware/DuetWiFiServer.bin not found

Tried a few older versions of that file name but all give that error.

Not sure where to go from here.

[oliof]

somewhere at the release train you are at now, Duet3D moved the firmware files from /sys to a dedicated /firmware folder.

Best way forward is to create that /firmware folder and moving firmware files (and the iap4e binary IIRC) there.

[Phaedrux]

Don't forget to update the DWC files. The version should match the firmware release version. Things will behave strangely or not work at all if they are out of sync. With such an old version who knows what will happen.

I tested updating from very old versions a while ago. You should be able to update straight to 3.0 from any version later than 1.19, so long as you have the in-app-programmer (iap4e.bin) in the sys folder. You appear not to be uploading the zip file of the firmware release, which should update DWC and WiFi server as well.

After updating to 3.0, you can update to the latest, just upload it twice, so firmware folder is created the second time and files are put in the correct place.

Occasionally the WiFi update hangs on update from 3.0 to later, and may need a manual update via USB.

@droftarts This morning I could not connect to the DWC. This morning I followed this video. Things were behaving a bit wonky and the file structure didn't match what was in the documentation so I figured I should start fresh. I followed the documentation for a new SD card and reformatted the card, and followed the above guide for flashing firmware. I tried substituting version 3.5.4 but I got a BOSSA error (I of course didn't write it down) so I figured I would just follow the guide explicitly.

And success! (?)

Looks like I'm successfully on version 3.1.1. I've copied my M122 below.

Can you confirm that the software versions are in order? I have:
Duet web control 3.5.0-rc.3
duet wifi server as 1.26
RR firmware for duet 2 wifi as 3.1.1

If that is correct, my next step is to install firmware version 3.5.4 through the DWC.

Edit:
Upon correcting my config file ( had some end stops set wrong) I get an error message about incompatible software:

Incompatible software versions

The installed software versions do not match. Please operate your setup only at equal versions to avoid potential incompatibilities and unexpected errors.

Please check out the docs on how to upgrade your Duet software components.

Now that you're on 3.1 you should upload these two zip files one at a time. don't extract them first.

[Mklein23]

@Phaedrux

will any config changes/pid tuning that I do on 3.1 need to be re-done after those updates?

[droftarts]

@Mklein23 yes, because the heater tuning parameters have changed. Just redo the heater tuning. You can do the tuning by tool now, which allows compensation for part cooling fans.

@droftarts said in Ajax communication error: connection terminated:

That's the only thing? Config.g and Homex/y/z and tool change files are unchanged?

[Mklein23]

@Phaedrux

Followed your instructions, and started with 3.3, downloaded the *-3.3.zip file, and did not extract it. I followed the "Usual procedure" on the updating firmware documentation, DWC prompted me if I wanted to install the new firmware, I clicked "yes."

I got this error:
M997 S0:1
Error: M997: In-application programming binary "Duet2CombinedIAP.bin" not found

I don't know if this is worth noting, but now my system directory is full of firmware files.

I thought the documentation said that the firmware files are supposed to go into a new file 0/firmware.

[Phaedrux]

What version does your DWC report? It will need to match 3.3, if it doesn't you can download the DWC SD zip file from the 3.3 release and extract it's contents to the www folder on the SD card to get back in sync.

What do you have in the firmware folder? Is that IAP.bin file present there?

[Mklein23]

@Phaedrux How do I check the DWC version?

I quick google search only brings up checking the firmware version, not the DWC version.

These are the only files in the 0/firmware folder:
