Anycubic Chiron Firmware 1.3.5 New! Download Info
Technical Brief: Anycubic Chiron Firmware v1.3.5 Implementation 1. Overview Anycubic Chiron Go to product viewer dialog for this item.
is a large-format FDM 3D printer that has undergone several firmware iterations. Version 1.3.5 is a factory-distributed update often found on newer Chiron units or provided directly by customer service to resolve specific hardware communication errors. Unlike standard open-source Marlin builds, this version is frequently distributed as a compiled package containing both motherboard (.hex) and screen (.bin) firmware components. 2. Official and Community Sources
Version 1.3.5 is notably absent from many of Anycubic's primary English support pages, but it can be found through regional repositories and community archives:
Direct Download (Official CN Server): The official Chinese Anycubic support site hosts the Chiron v1.3.5 ZIP package.
GitHub Repositories: Users have uploaded requested source files and compiled versions to GitHub Issue Threads to assist those with "bricked" screens or broken factory installs. 3. Installation Procedure
Updating to v1.3.5 typically follows one of two paths depending on the file format received: Method A: Cura Slicer (Standard .hex) Anycubic Chiron Firmware 1.3.5 Download
Connect the printer to a PC via a high-quality USB data cable. Open Ultimaker Cura and navigate to Manage Printers Select the Anycubic Chiron and click Update Firmware.
Choose Upload Custom Firmware and select the v1.3.5 .hex file. Method B: SD Card (For Screen/TFT Firmware)
Warning: Users have reported that flashing the screen firmware included in some 1.3.5 ZIP files can lead to an unresponsive display.
If necessary, the .bin file is placed on the root of a formatted SD card and inserted into the display's dedicated slot (not the printer's main slot) before powering on. 4. Known Issues and Stability
While v1.3.5 aims to fix file offset errors and power-loss recovery, it has a documented history of community-reported bugs: Technical Brief: Anycubic Chiron Firmware v1
Screen "Bricking": Flashing the screen firmware without specific instructions from Anycubic often results in a permanent progress bar or total loss of touch functionality.
Homing Failures: Some users reported that Z-homing functionality, which worked on v1.3.0, failed immediately after updating to v1.3.5.
Auto-Leveling Conflict: Downgrading or incorrectly flashing the firmware often breaks the printer's unique 25-point auto-leveling system. 5. Recommended Alternatives
Due to the lack of official documentation for v1.3.5, many advanced users recommend transitioning to community-maintained Marlin 2.x builds:
Nick Wells Marlin 2.0.7: A popular stable alternative that supports the stock Chiron hardware while adding features like Linear Advance and improved thermal runaway protection. Troubleshooting After Installation
TH3D Unified Firmware: A simplified Marlin branch that allows for easier configuration via VSCode.
Troubleshooting After Installation
- Printer won’t boot (blank screen) – Reflash, ensuring you selected the correct COM port and board type (Sanguino 1284p 16MHz).
- Z-axis makes grinding noise – Reset EEPROM as described; then redo Z offset calibration.
- Temperatures read “0” or “def” – Thermistor connection loose; power off, check wiring.
- Can’t upload via USB – Install CH340 USB driver (common for Anycubic boards).
5. Installation Procedure
This process involves overwriting the motherboard's flash memory. Do not power off the printer during this process.
