DuetRFF Cura plugin Duet 3

I am discussing with my colleagues the best way to get all the upload plugins working with Duet 3 + SBC. What I don't want is for users to have to choose one of two different plugins according to their Duet configuration, because that would inevitably result in a lot of forum support due to users selecting the wrong one.

@resam I can see the same result as @Sotidii

It seems that the mode-switch is not working. What makes me wonder is that it says 203 Error as if that would be a HTTP/203 return code though when I call this URL directly I get the (correct) HTTP/404.

@wilriker Cura uses Qt - and Qt introduced their own error codes:
https://doc.qt.io/qt-5/qnetworkreply.html#NetworkError-enum
i.e., QT 203 means more or less HTTP 404.

@Sotidii @wilriker I pushed another code change to hunt the the problem with the mode switch. Please post parts of your Cura log. On macOS you can find the log under ~/Library/Application\ Support/cura/4.5/cura.log. Or on Windows under C:\Users\<Username>\AppData\Roaming\cura\4.5\cura.log. I'm only interested in lines with Cura-DuetRRFPlugin.DuetRRFOutputDevice in it.

Thanks!

@resam sorry me for delay.
I can't do anything at the moment, I disassembled the printer to finish some works with duet 3

@Sotidii @wilriker I just realised that my original instructions where probably a bit misleading. Here the correct ones:

Please follow this link to download the correct testing version:
https://github.com/Kriechi/Cura-DuetRRFPlugin/archive/duet3-sbc-DuetSoftwareFramework.zip

Then, with Cura not running, unpack the zip file to this specific folder:

• Windows: C:\Users<username>\AppData\Roaming\cura\4.5\plugins\DuetRRFPlugin
• macOS: ~/Library/Application Support/Cura/4.5/plugins/DuetRRFPlugin
• Linux: /home/<username>/.local/share/cura/4.5/plugins/DuetRRFPlugin

Be careful, the unzipper often tacks on the name of the zip as a folder at the bottom and you don't want it nested. You want the files to show up in that folder.

Make sure that the plugin folder name is a listed above and it does not have any trailing version numbers (-1.0.0) or similar.

@resam Hi Thomas,

first I have to admit that accidentally I was on the wrong branch when testing before. Now I am on the correct branch but still get an issue. I even get a Cura pop-up with a traceback:

Traceback (most recent call last):
  File "/home/manuel/.local/share/cura/4.5/plugins/DuetRRFPlugin/DuetRRFOutputDevice.py", line 201, in _check_duet3_sbc
    Logger.log("d", self._name_id + " | rr_connect failed with errorCode " + errorCode)
TypeError: can only concatenate str (not "NetworkError") to str

There is no logging line containing Cura-DuetRRFPlugin.DuetRRFOutputDevice though.

@wilriker thanks - almost an expected error.
I pushed another commit - please try again.

@resam said in DuetRFF Cura plugin Duet 3:

@Gio @Danal if you could install the plugin manually and give it a test - and send me the Cura log output back - it would be much appreciated!

Been away for a bit, back now.

Will do.

@resam So upload works with latest commit now. Simulating fails with

Traceback (most recent call last):
  File "/home/manuel/.local/share/cura/4.5/plugins/DuetRRFPlugin/DuetRRFOutputDevice.py", line 216, in onUploadReady
    self._stream.seek(0)
ValueError: I/O operation on closed file

I could not test printing right now (and won't be able to before tomorrow) but I guess if Simulate works, Start print will also work.

Big shout out to @wilriker for a quick live debugging session!

It looks like the Cura-DuetRRF plugin now should fully support Duet3+SBC printers.
I will keep the dedicated branch for a few more days - anyone who is interested in testing, please grab a copy of the plugin here: https://github.com/Kriechi/Cura-DuetRRFPlugin/archive/duet3-sbc-DuetSoftwareFramework.zip

I plan to upload an updated plugin version into the Cura Marketplace on the weekend. Please let me know if you encounter any issues.
