Sunlu T3 Firmware [exclusive] Link

If you are nervous about compiling code, stick to the official T3_V1.0.4.bin from Sunlu support. If you want to turn your budget T3 into a high-speed, high-quality machine, learn to compile Marlin 2.1.x or switch to Klipper.

The Sunlu T3 (often called the Terminator 3) is a popular FDM 3D printer known for its impressive price-to-feature ratio and high-speed printing capabilities of up to 250mm/s. Its heart is a 32-bit silent motherboard, which is a modified version of the BTT SKR Mini E3 V2 board, running TMC2209 stepper drivers in standalone mode.

The Sunlu T3 is a capable machine whose potential is unlocked through its firmware. While the official software provides a solid foundation, the power of the open-source Marlin and Klipper communities offers a path for enthusiasts to fix quirks, add features, and push their printer further.

Compile the firmware using the make command, transfer the resulting Klipper .bin file to an SD card, and flash your T3 motherboard. If you are nervous about compiling code, stick

The is a Cartesian FDM 3D printer (a clone of the Artillery Hornet / modified i3 design). It runs on a 32-bit board (usually a proprietary STM32-based variant) with a touchscreen UI. Unlike Marlin-based printers with LCD12864, the T3’s firmware is a specialized Marlin fork integrated with a GUI for its color touch display.

. Analysis of the source code shows this mode primarily overrides standard acceleration and speed limits in the configuration rather than implementing advanced algorithms like Input Shaping. Auto Bed Leveling (ABL): Supports a

The (also known as the Terminator 3) is a high-speed FDM printer marketed for its ability to reach speeds of up to 250mm/s . While its hardware—a dual-gear extruder and 32-bit silent mainboard—supports this, the firmware is the true engine behind these capabilities. Its heart is a 32-bit silent motherboard, which

If you want to unlock the true speed of the Sunlu T3 (90mm/s+ with quality), install Klipper. The process involves:

Updating the stock firmware is straightforward. The consensus across user forums is that the process is simple and reliable.
