BIGTREETECH SKR Mini E3 V1.x and V2.x mainboards are ultra-quiet, low-power, high-quality 3D printing machine controller boards from BIQU.
These and other SKR mainboard/motherboard for 3D-printers are produced by the 3D printing team of Shenzhen Bigtree Technology Co., Ltd.
The first BIGTREETECH SKR Mini E3 V1.x 32-bit control boards with integrated TMC stepper-drivers was initially specially designed to be a drop-in replacement upgrade board for the Ender 3 printers by Creality, making replacing the original 8-bit mainboard/motherboard hardware used by the very popular Ender-3 3D-printer quick and easy for most users. Software updates have since released also added compatibility for other 3D-printers with a single Z-axis stepping-motor, including support for CR-10, CR-10 Mini, Ender 3 Pro from Creality.
BIGTREETECH SKR Mini E3 V2.x has added additional hardware improvements and enhancements based on community feedback. Among other things, these improvements and enhancements with SKR Mini E3 V2.x include two Z-axis interface ports, and SKR Mini E3 V2.x is today, in addition to the 3D-printers already support by the V1.x boards, also compatible with CR-10S, CR-10 S4, CR-10 S5, Ender 5, Ender 5 Pro, and Ender 5 Plus from Creality.
Pre-tested Marlin Firmware configuration example files for these 3D-printers with stock is available in an upstream repository here:
Note: If your motherboard version is BTT SKR Mini E3 V1.x, please check the correct BIGTREETECH-SKR-mini-E3 V1.x documents which are located respectively in both the firmware directory and hardware directory with that version.

Note! After refreshing the new firmware, please always restore defaults first and then store settings, the new coordinates used for levelling will take effect, LCD option path: Configuration-> Restore defaults, Configuration-> Store settings.
Disclaimer! Marlin firmware needs to be configured aND CUSTOMIZED by the customer themselves, the reason for this is that BIQU / BIGTREETECH does not know the specific hardware configuration of each individual customer and can therefore not support individual configuration of special firmware specific to each customer. BIQU customer service will however if contacted provide configuration suggestions if details on your specific hardware setup are described.
