 In `Configuration.h` enable the `MOTHERBOARD BOARD_BTT_SKR_SE_BX_V3` option at the top to specify the BTT SKR SE BX V3.0 motherboard, otherwise the V2.0 board will be applied (slightly farther down).
 
 Enable the `BX_ALL_METAL_HOTEND` option to permit higher printing temperatures for the newer H2 extruder with an all-metal heatbreak.
