Investigating Anycubic Chiron Firmware 1.3.5 reveals a complex landscape where the "official" version is often difficult to source, leading many users to seek "repacks" or custom alternatives. While version 1.3.5 is the stock firmware for newer Chiron models, it is not always publicly listed on Anycubic's primary support pages, which frequently point back to version 1.3.0. The Role of Firmware 1.3.5

Firmware 1.3.5 was primarily released to support hardware variations in the Chiron's production run, specifically different TFT panel types. Using older firmware like 1.3.0 on a newer machine can disable critical features like auto-leveling or cause the touchscreen to become unresponsive. Repacks and Alternative Sources anycubic chiron firmware 135 download repack

Because 1.3.5 is hard to find officially, the community has created "repacks" or custom builds:

Official Repacks: Some users have mirrors of the original v1.3.5 Direct Link Example from Anycubic's Chinese servers.

Warning on Screen Flashing: Expert users warn not to flash the screen firmware included in some 1.3.5 zip files unless absolutely necessary, as it can brick the display.

Custom Community Firmware: Many owners opt for Marlin 2.x repacks which include 1.3.5 hardware compatibility while adding features like Thermal Runaway Protection and PID tuning. Update and Installation Methods Updating a Chiron typically follows one of two paths:

Anycubic Chiron Firmware 1.3.5 Repack Report This report summarizes the details, features, and installation procedures for the "repacked" version of the Anycubic Chiron firmware, specifically version 1.3.5. While the stock firmware provides basic functionality, community-driven repacks often fix bugs and unlock features like manual mesh leveling.

The Anycubic Chiron is known for its massive build volume but often struggles with stock firmware limitations. Version 1.3.5 Repack is a community-optimized version of the original factory code, designed to improve print reliability and user control without requiring a complete move to Marlin 2.0. Key Features of the 1.3.5 Repack Enhanced Mesh Leveling: Improves the accuracy of the 25-point probing system. Thermal Runaway Protection:

Ensures the printer shuts down if temperature sensors fail, preventing fires. Babystepping:

Allows for real-time Z-axis adjustments during the first layer of a print. EEPROM Access: One user wrote: “After three failed prints and

Enables users to save calibrated E-steps and PID tuning directly to the board. Bug Fixes:

Addresses UI freezes and SD card reading errors found in earlier factory releases. Download and Prerequisites To install this firmware, you generally need the following: Firmware File: Typically a file (e.g., Chiron_v1.3.5_Repack.hex Connection: A USB-B cable to connect the printer to a PC. Cura (Firmware Update Tool) or PrusaSlicer. Installation Steps Backup Settings: Record your current E-steps and PID values. Connect Printer: Plug the Chiron into your PC via USB. Open Cura: Settings > Printer > Manage Printers Update Firmware: Update Firmware and choose Upload Custom Firmware Select File: Choose the downloaded 1.3.5 Repack Reset EEPROM: After flashing, send the followed by G-code commands to initialize the new settings. Important Considerations Calibration is Required:

After flashing, you must recalibrate your Z-offset and bed leveling. Hardware Compatibility:

Ensure your Chiron uses the standard Trigorilla motherboard; some newer versions may have slight variations. If you'd like to proceed with the update, let me know: Do you have the original Trigorilla board or a replacement? Are you comfortable using G-code commands via a terminal (like Pronterface)? Would you prefer a version specifically optimized for stock leveling probe

I can provide specific calibration steps once the firmware is loaded.

While the 1.3.5 repack is the safest choice for purists, note that Knutwurst and others have released Marlin 2.0.9.x repacks for the Chiron. These offer:

However, 2.0.x requires a bootloader update and sometimes hardware modifications (removing capacitors from the stepper drivers). For most users, the v1.3.5 repack remains the “just works” golden standard.
