Sunlu T3 Firmware [verified] Jun 2026

The SUNLU T3 typically updates via its microSD card slot: 0;16; 0;265;0;522;

The LCD connector on the T3 is sometimes wired differently than the Ender 3 V2. If you flash Mriscoc and get a blank screen or "No Printer Attached," your ribbon cable might need to be reseated or you need the DWIN display firmware update. sunlu t3 firmware
