The Sunlu T3 is a fantastic budget 3D printer, but like all technology, it benefits from regular updates. The V3.43 firmware update is a small, free investment of time that pays off with , more reliable clog detection , and overall improved stability .
The stock firmware was fine—safe, boring, and full of artificial limits. The acceleration was capped like a minivan. The mesh bed leveling only used three points, ignoring the warped corner she knew existed. She had heard whispers online about a community-built firmware for the T3, one that unlocked the TMC2208 drivers in UART mode and added features the OEM never intended.
