Skip unable to open V8 *.kicad_pcb files

[go2dev]

Skip fails to open PCB files if they were saved from Kicad V8. The parser returns the same error when using skip as a library in another script or interactively in a REPL session. Kicad V7 PCBs open correctly. Schematics also open correctly from both V7 and V8 files.

Example error:

pcb8 = skip.PCB("C:\Dev\myProject\Control Board\LEDTest_controlboard_8.kicad_pcb")

Tested on:

• Intel i7 5930K // Windows 10 x64 22H2 // Python 3.10.6 // kicad-skip 0.2.5
• M1 Macbook Pro // MacOS Sonoma 14.5 // Python 3.10.13 // kicad-skip 0.2.5

Test files:
LED_BOARD_REFv8.zip created in KicadV8 - fails to open

I'm not sure what _base_coords is so creating them in place or wrapping this bit in a try-catch doesn't seem sensible.

Anything that can be done the file PCB files to make them readable? (rather than changing the skip code).

I also receive the same error now when using KiCAD 8 and skip
