Windows 10 Pro

Additional system information

Path building mixes back slashes and forward slashes, creating a mess that Windows/Python chokes on.

Post-processing script "C:\Users\Eric\AppData\Local\Python\bin\python.exe"
"F:\Bricklayers-main\bricklayers_my.py" on file
C:\Users\Eric\AppData\Local\Temp/snapmaker_orca_model/Tue_Aug_25/23_25_58#31824#3047/M
etadata.31824.10.gcode.pp failed.
Error code: 1

Note how the Temp file path starts with backslashes, switches to forward slashes, then reverts to one last backslash at the very end.

This works correctly in vanilla Orcaslicer, and has for well over a year.

Printer

Snapmaker U1

How to reproduce

1. Make a basic python post processing script that accepts a path from the slicer (go use the Bricklayers script from github, for a quick one)

2. Add script to post-processing

3. Slice

4. Attempt to PRINT or SAVE AS GCODE file.

5. See error similar to mine, with mangled temp path.

Actual results

Expected results

Proper formation of path to temp file, and successful processing of gcode, which is then uploaded or saved.
