: A user named Kaot93 released a popular Custom Firmware for SUNLU T3 on Printables. It enables 5x5 point Auto Bed Leveling (ABL) , raised hotend temperatures for all-metal setups (up to 285°C), and PID tuning for both the bed and hotend [23].
An advanced user named Anson Liu has created a custom Marlin configuration for the Sunlu T3 using the latest Marlin 2 bugfix branch. This custom build fixes several issues present in the stock firmware: Before changing firmware to fix "heat creep," verify
