Keeping your Sunlu T3 firmware up to date ensures optimal printing performance, access to new features, and resolution of known issues. This guide covers the two main firmware components:
Before starting, check your current firmware version via the printer’s Info or About menu.
Warning: Do not download random "T3 firmware" from a sketchy Google Drive link.
Updating the firmware on your can unlock enhanced features like better temperature stability, improved "Fast Print" acceleration, and even bug fixes for SD card printing. Since the T3 uses a modified BTT SKR Mini E3 V2 Go to product viewer dialog for this item.
motherboard, it is essentially a high-speed Ender 3 clone that runs on Marlin 2.0. Preparation Checklist
Before starting, ensure you have the following ready to avoid "bricking" your machine:
MicroSD Card: Use a low-capacity card (8GB or 16GB is ideal) formatted to FAT32 with a 4096 allocation unit size.
Latest Firmware: Download the official .bin file from the SUNLU Support Page or reliable community repositories like GitHub. sunlu t3 firmware update better
Record Current Settings: Note your current Z-offset and E-steps values, as these will likely reset after the update. How to Update Your Firmware Sunlu S8: How to Update the Firmware
Looking to get more out of your SUNLU T3? While the stock experience is solid for many, upgrading the firmware can unlock better performance and fix persistent bugs. Why Update Your SUNLU T3?
Upgrading your firmware isn't just about getting the "latest" version; it often solves specific hardware quirks.
Fixing Component Errors: Some users have found that updates help with probe self-test failures.
Safety Features: Newer Marlin-based builds often include better thermal runaway protection.
Improved Efficiency: Custom versions can optimize the extruder cooling fan, which sometimes fails to stay on during hotend maintenance in stock versions.
Better Customization: You can adjust build volume limits (from 220x220 to the physical 235x235) and tune acceleration for faster prints. Official vs. Custom Firmware There are two main paths you can take:
Official SUNLU Updates: SUNLU occasionally releases updates like v3.40, which focuses on language support and LCD refresh rates. You can check for official support on the sunlu 3d Facebook page. Note: If your printer is stable on v3.31, some users suggest staying there, as v3.40 has reported heating sensor bugs for some units.
Custom Marlin Firmware: For more control, many users prefer community-created Marlin builds. You can find highly recommended versions like the Custom Firmware for SUNLU T3 by Kaot93 on Printables.com. These often include features like 5x5 point Auto Bed Leveling and babystepping.
