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.).
If you own an Anycubic Chiron, you know it’s a beast of a printer—massive build volume, sturdy frame, and, when tuned correctly, capable of producing stunning large-format prints. However, like many budget-grande 3D printers, the Chiron’s Achilles’ heel is often its stock firmware. Enter the sought-after Anycubic Chiron firmware 1.3.5 download repack.

The repack only works fully if the LCD firmware matches. Stock LCD firmware will show scrambled menus.
Some users modify firmware to:
These modified firmwares are often shared on forums like: anycubic chiron firmware 135 download repack
But they are NOT official "repacks" – they are custom compilations.
The Anycubic Chiron uses a Trigorilla motherboard (often version 0.0.2, 0.0.3, or 0.0.4). The repack ensures the pin mappings, thermistor tables, and stepper driver currents are correct. Using a vanilla Marlin build can brick your LCD.
"Repack" firmware is not an official release from Anycubic. Repacks are third-party modifications that may contain:
Always download firmware from official sources only.
As of this writing, the most reliable source is the Knutwurst GitHub repository. User “Knutwurst” is the de facto hero of the Chiron community. His repack of Marlin 1.3.5 (and later 2.0.x) fixes the core issues. The Anycubic Chiron is a large-format FDM 3D
