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've had to go
1.19(start) > 1.2 > 1.21 > 2.0 > 2.1 > 2.05 > 3.0I 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.
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 3.1.1If 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.

https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/Duet2and3Firmware-3.4.6.zipNow that you're on 3.1 you should upload these two zip files one at a time. don't extract them first.
-
will any config changes/pid tuning that I do on 3.1 need to be re-done after those updates?
-
@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.

That's the only thing? Config.g and Homex/y/z and tool change files are unchanged?
-
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 foundI 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.
-
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?
-
@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:
-
Check the settings > general tab on the left bar.
https://docs.duet3d.com/en/User_manual/Reference/Duet_Web_Control_Manual#settings-general
-
@Phaedrux Finally getting back around to this. I actually had some prints to do and other house projects to wrap up.
Looks like I'm running duet web control 3.3.0 and RR firmware at version 3.1.1
Aren't those 2 versions supposed to match?
Should I try and install version 3.3 again?
-
@Mklein23 If looks like DWC got updated, but RRF didn't, because of this error:
Error: M997: In-application programming binary "Duet2CombinedIAP.bin" not found
You need the Duet2CombinedIAP.bin file in your /sys folder. Download "Duet2CombinedIAP.bin" from https://github.com/Duet3D/RepRapFirmware/releases/tag/3.1.1 and upload it to your sys folder, then send
M997 S0to update the firmware to 3.3.Then download the RRF 3.4.6 zip and update to that:
https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.5/Duet2and3Firmware-3.4.6.zipIan
-
Duet web control is at version 3.4.6
RR firmware is at version 3.4.6Thank you so much for your patience and assistance throughout this adventure.
I added the combined IAP file, then re-installed the 3.3.0 combined.zip file for 3.3.
That installed perfectly, then I installed the 3.4.6 combined zip and it just worked.

@Mklein23 great, hopefully this resolves the initial problem of not being able to connect to DWC!
