Sunlu | T3 Firmware [upd]
Use these at your own risk – you will lose touchscreen support unless you port the DGUS LCD.
If you need help tailoring this firmware setup to your specific printing goals, please let me know:
The 3D printer is widely regarded as a high-value, fast-printing Ender-3 clone, often applauded for its out-of-the-box performance and automatic bed leveling. However, the true potential of this 32-bit machine is unlocked through its firmware .

(also known as the "Terminator 3") is often described by enthusiasts as an "Ender 3 clone" with some significant "under the hood" quirks, making a firmware update one of the most recommended first steps for new owners. 🏆 Top Recommended Resource
Because the Sunlu T3 architecture closely mirrors the Creality Ender 3 Neo series, many users compile custom Marlin firmware using VS Code and Auto Marlin Builder. Key Compiling Edits
For users seeking to push the performance envelope, is a revolutionary alternative. Unlike Marlin, Klipper uses a powerful external computer (like a Raspberry Pi) to handle calculations, freeing the printer's mainboard to simply execute movements. This can enable higher print speeds and advanced features like input shaping for vibration compensation. What is your
Because the stock firmware's "Fast Print" mode is somewhat opaque, many users opt for custom builds to unlock better control or fix specific bugs. Kaot93’s Custom Firmware : Available on Printables.com , this build enables features like 5x5 Automatic Bed Leveling (ABL)
Z-offset or probe offsets are incorrectly defined in the new firmware.
Uses an accelerometer to measure the vibrations of your T3 frame. It then uses algorithms to cancel out those frequencies, completely eliminating ghosting and ringing at 150mm/s+ speeds.
