Does stickerbom work in KiCad 6.0?

[Phozer]

First of all, great Project!

I tried using the stickerbom.py to create labels to stick on my component bags. I face some problems using it, so I want to ask if it even works with KiCad 6.0?

This is what i get as output.

python C:\03_Data\repos_external\git\agg-kicad\scripts\stickerbom.py C:\03_Data\repos\SVN\TestAutomation\TestAdapter\SNIFX\SNIFX.QP2\2_KiCad\SNIFX.xml C:\03_Data\repos\SVN\TestAutomation\TestAdapter\SNIFX\SNIFX.QP2\2_KiCad

Thanks for opening the issue! It looks like KiCad 6 made a few changes that broke stickerbom, mostly renaming "modules" to "footprints" in the board file and changing how graphic arcs are represented from "centre, start, angle" to "centre, mid, end". I've just pushed an update to stickerbom that seems to work for me on some KiCad 6 boards, could you check if it works for you?

Thanks for your quick fix. Seems to work much better than before. Now i have this issue:

C:\03_Data\repos_external\git\agg-kicad\scripts>python stickerbom.py C:\03_Data\repos\SVN\TestAutomation\TestAdapter\SNIFX\SNIFX.QP2\2_KiCad\SNIFX.xml C:\03_Data\repos\SVN\TestAutomation\TestAdapter\SNIFX\SNIFX.QP2\2_KiCad\stickerBOM.pdf

    cr.show_page()
__main__.cairo.MemoryError: out of memory

I tried with different boards, all get this same error. A PDF gets created but it's blank.

Hm, that's odd. It seems like this might be an issue with PyCairo on Windows, see https://github.com/pygobject/pycairo/issues/239. Perhaps you could try the builds linked there, or a Linux/WSL build?

[Phozer]

Do you have e public project which worked for you? Then I can check for differences and troubleshoot. Would love to get this to work.

[Phozer]

Works now. My Problem was that I had to add the Field name to stickerbom.py line 523. My Field name is Mouser-Nr.and not one of the already ones mentioned there: Farnell,RS,DigiKey,Digikey,Mouser. The empty PDF mislead me to some problems with pycairo and not my wrong usage of the script or not providing the correct data. Maybe Info could get printed out in such cases that the user gets notified that Supplier Numbers are necessary.

Is there an option to use the copper layer instead of the fab layer for the drawings?

[adamgreig]

Ah cool, glad you figured it out! There's not a built-in option at the moment, but if you change F.Fab for F.Cu and B.Fab for B.Cu on lines 579-593 that should do it; currently it uses F.Fab first but if a footprint doesn't have any items on the fab layer it will instead render use the copper and silkscreen layers.

I will now close this Issue because for me it's fixed now. I just noticed that my Board outline did not get drawn. Just if you bother you may fix that. Thanks for your work. It helped a lot.

[adamgreig]

Thanks for sticking with it, I'm glad it's working for you now! Not sure what's up with the board outline, I'll try and look into it.
