Not able to run third party scripts on macOS

electrophile · February 6, 2021, 4:53am

I came across these awesome scripts from Greg Davill for exporting beautiful images of the board layouts, silkscreens etc. I will later import these in Fusion 360 to create a realistic 3D model of the final board. I’m on a Mac running Mojave and this thread helped a little towards running these scripts from the python builtin with KiCad. However, I get the following errors listed below. I’m fairly a newbie when it comes to Python and any help in running these would be appreciated.

How exactly are you running the script? Can you post your full command here?

electrophile · February 6, 2021, 9:02am

python plot_board.py /path/to/kicad_pcb_file/pcb.kicad_pcb

qu1ck · February 6, 2021, 9:24am

Are you using python from kicad app and not system python? Have you added sys.path patch as described here Running a KiCad script on MacOS ?

electrophile · February 6, 2021, 9:58am

Yes. This is the modified python file. Inkscape path is on line 422.

I don’t know how to help you further, the error seems related to macos codesigning issues. Report this on kicad gitlab if you can.

But if your goal is to get pretty image of the board then you can try importing the board into freecad using KiCad StepUp tool plugin and that will give you actual 3d model of the board with copper and everything, you can then use that model in your rendering software.

Another option is to use https://www.pcbway.com/project/OnlineGerberViewer.html

It allows you to save pretty svg files like this

Thank you for trying. The boards that you can export as STEP from KiCad are sufficient TBH. I just wanted to see how I can make them more realistic.
