Fusion 360 post — the 2026 update broke my tool numbering

Posted G-code now outputs T0 instead of the assigned tool number. CAM project worked fine before the Fusion 2026 update.

Anyone else hit this after the Fusion 360 February build? My existing CAM project posts correctly except every tool change line outputs T0 instead of the actual tool number from the library.

Tested:

  • Re-installing the CycleCNC post from the Post Processor page — no fix
  • Manually reassigning tool numbers in the library — change saves but doesn't carry into posted G-code
  • Opening the same project in Fusion 2025 — posts correctly

Looks like a Fusion-side regression rather than a post issue. Workaround: I'm hand-editing the .nc file. Any cleaner fix?
