| Issue | Description | |-------|-------------| | Auto-leveling | Often fails or produces incorrect mesh; requires multiple runs. | | Thermal runaway | Protection not fully enabled in all configurations. | | TFT response | Slow UI, occasional freezes. | | Filament runout | May trigger false positives or ignore sensor. | | Max temperature | Limited to 260°C (not ideal for high-temp materials). |

Official firmware for the Anycubic Chiron is based on Marlin—the open-source 3D printer firmware. Version 1.3.5 (often stylized as v1.3.5) was one of the last official stable releases before Anycubic shifted focus to newer machines like the Kobra series.

Key features of the original stock v1.3.5 include:

However, the term “repack” is where the real value lies.

| Problem | Solution | |--------|----------| | White screen / no text | You didn’t flash the LCD firmware. Re-do Part 2. | | “Thermal runaway” error immediately | Bad thermistor connection. Check the hotend and bed thermistors. The repack is more sensitive—this is actually a feature, exposing a real wiring issue. | | Printer moves backwards | Incorrect board version. If you have a Trigorilla Rev. A, invert the X/Y axes in the repack’s Configuration.h and recompile. | | Can’t flash—timeout error | Your board’s bootloader is locked. Use an Arduino Uno as an ISP programmer to burn a new bootloader (advanced—see YouTube tutorials). |

Anycubic Chiron firmware 1.3.5 represents a critical transition in the lifecycle of this large-format 3D printer, particularly concerning hardware compatibility and stability. While the 1.3.0 version was the longstanding standard, later models of the Chiron shipped with a different TFT screen panel that requires version 1.3.5 for full functionality. The Evolution of Chiron Firmware

The Chiron's firmware history is defined by the hardware it supports. Users with older machines often find that the 1.3.0 version available on the main Anycubic website works perfectly. However, those with newer units may encounter issues if they attempt to flash older versions, as the updated screen panels are not backward compatible with version 1.3.0. This has led many to seek "repacks" or specific downloads of 1.3.5 to restore features like auto-leveling. Key Features of Version 1.3.5 Hardware Support:

Specifically designed for newer TFT screen panels that are incompatible with older firmware versions. Functionality Restoration: Filename example (official): Anycubic Chiron V1

Resolves issues where auto-leveling becomes "locked out" or non-functional after flashing older or incorrect firmware. Official Origin:
