The Anycubic Chiron was released with two distinct hardware revisions:

Version 1.3.0: Found on older machines with white/blue screen themes.

Version 1.3.5: Required for newer machines with blue/yellow screen themes.

The Anycubic Chiron is a large-format FDM 3D printer (400×400×450 mm). The stock firmware shipped with early models was often v1.3.0 or v1.3.5. While v1.3.5 is the last official release from Anycubic, it still contains bugs (e.g., inconsistent auto-leveling, thermal runaway protection not fully reliable, poor TFT responsiveness). Consequently, the community has created “repacks” — modified versions of v1.3.5 that fix bugs, enable safety features, and improve usability.

Important: Anycubic no longer hosts v1.3.5 on its official site. The most reliable source is community repositories (GitHub, Thingiverse, etc.).
