@MiguelASTavares can you see the version of the plugin anywhere in the gui? Want to confirm its the latest version.

[MiguelASTavares]

@chmorgan Can you tell me where to look for the version? In the top of the window, I have “JLCPCB Tools [dev]”. I have cloned the repository, but I have also tried to add the repo to the Plugin manager of KICAD, but had the same behavior.

I had exactly same issue on Windows 11 + KiCad 8.0.2 + kicad-jlcpcb-tools 2024.05.01 until I have removed the database and let kicad-jlcpcb-tools 2024.05.01 re-creacte it from scratch

[MiguelASTavares]

I have tried to downgrade the KICAD install to 8.0.1, and it worked (on windows), but in Linux I'm not seeing an easy way to downgrade. @bvernoux how did you remove the database and re-created?

I have tried to downgrade the KICAD install to 8.0.1, and it worked (on windows), but in Linux I'm not seeing an easy way to downgrade. @bvernoux how did you remove the database and re-created?

1. Quit/Exit KiCad 8.0.2 (check with ProcessExplorer ... that there is no any KiCad instance running, if yes do Kill process on KiCad instance(s) you see) then just delete the jlcpcb directory in the project (it include project.db ...).
2. Start KiCad 8.0.2, remove Bouni JLCPCB plugin then quit KiCad (check there is no running instance of KiCad again ...)
3. ReStart KiCad 8.0.2 reinstall Bouni JLCPCB plugin kicad-jlcpcb-tools 2024.05.01
4. Open your project and launch jlcpcb plugin and it will recreate jlcpcb/project.db ...
   Now all shall work fine

[MiguelASTavares]

I tried to do this steps, but the plugin is still not working. Any other ideas?

[Bouni]

@MiguelASTavares Can you give the latest release a shot?

[MiguelASTavares]

I have updated the plugin it's now on: JLCPCB Tolls [2024.06.02], the behavior remains the same. I can't open the Assign LCSC number button.

[Nick-Doe]

Same issue here re-installed as suggested
Started jlcpcb tools - database updated as normal
No partslist comes up
exit jlcpcb tools
restart

Exit kicad and kill remaining kicad task
Restart kicad
start jlcpcb tools
everything looks ok but cannot assign part
cannot right click paste part

[Nick-Doe]

I have noticed the exception may happen several times when trying to start jlcpcb tools. Eventually the parts display comes up and then seems to come up reliably. Still not part assignment

Additional attempts:

Reverted back to old tools version

Install plugin via Plugin manager: KiCAD-PCM-2024.05.01.zip

Overwrite mainwindow.py with changed one: 30856ea

Same behavior.

Reverted back to previous Kicad May 26 2024 00:43:30

Same behavior.

With existing designs, BOM output format is now wrong. Gerbers seem ok. Not sure about cpl files.
