Anycubic Chiron Firmware 135 [better] — Download Repack

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:

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: anycubic chiron firmware 135 download repack

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

The Anycubic Chiron firmware 1.3.5 is an official update primarily released for newer Chiron models equipped with specific screen hardware. While users often seek "repacks" for extra features, version 1.3.5 is frequently used as a base for custom Marlin builds or to restore original functionality on newer machines.  Download Sources 

Finding version 1.3.5 can be difficult as it is not always listed on the main English support page. You can typically find it through the following channels: 

Official Chinese Support Portal: Anycubic often hosts newer or region-specific firmware here. You can download the Firmware 1.3.5 Zip directly, but use caution with the included screen files.

Official Global Site: Check the Anycubic Firmware & Software page for the latest updates, though version 1.3.0 is more common there. Anycubic Chiron Firmware 1

Community Repacks: For advanced features like baby stepping or improved thermal protection, many users prefer third-party Marlin builds such as Nick Wells' Marlin 2.0.7 package.  Installation Guide 

Installing version 1.3.5 usually involves flashing a .hex file to the motherboard. 

Preparation: Connect your printer to your PC via a USB data cable. Using Cura:

Open Cura Slicer and add the Anycubic Chiron as your printer. Navigate to Settings > Printer > Manage Printers. Select your printer and click Update Firmware.

Choose Upload custom Firmware and select the .hex file from your 1.3.5 download.

Alternative (XLoader): For a lightweight option, use XLoader. Select the ATmega2560 device, the correct COM port, and set the baud rate to 115200 before clicking Upload.  ⚠️ Critical Warnings  Thermal Runaway is spotty – Not safe for

Why Do People Search for a “Repack”?

The stock 1.3.5 firmware has three famous problems:

1. Thermal Runaway is spotty – Not safe for unattended printing.
2. No Mesh Bed Leveling (ABL) integration – The stock sensor works, but the firmware doesn’t use the mesh well.
3. Loud stepper motors – No “StealthChop” enabled.

A “repack” usually means someone has compiled a custom version of Marlin that:

• Enables thermal runaway protection (critical).
• Adds M600 filament change.
• Improves bed leveling.
• Sometimes adds Linear Advance.

⚠️ HUGE WARNING: Downloading “Repacks” is Risky

Before you grab that random .hex or .bin file from a Dropbox link in a Reddit thread from 2021, know this:

• Brick risk: The Chiron uses two different mainboards (Trigorilla and a later revision). Flashing the wrong “repack” = dead screen + dead printer.
• Malware: Executable flashers (like Cura’s firmware flasher) can contain keyloggers.
• No support: If the repack breaks your Z-offset, you’re on your own.

Phase 3: Update the LCD Firmware (Critical)

The repack only works fully if the LCD firmware matches. Stock LCD firmware will show scrambled menus.

1. Format a microSD card to FAT32, 4096 bytes allocation unit.
2. Copy DGUS_Chiron_135.hex to the SD card and rename it to DWIN_SET (if required).
3. Power off the Chiron.
4. Insert SD card into the back of the LCD screen (remove back cover).
5. Power on. The screen will flash blue/orange for 30 seconds.
6. Remove SD card and power cycle.
