## Two Trees Sapphire Configurations

|
|
| V2.1| MKS Robin Nano V1.3|1|
|

|
Make sure you always test the endstops/limit switches after using this configuration, as newer printers may have slight electrical and mechanical differences.

## Available options
|
|
|
|
By default the standard Marlin Touch UI will be used. Enable the `SAPPHIRE_PLUS_MKS_UI` option for the MKS UI.
|
|
|
|
Enable the `SAPPHIRE_PLUS_BLTOUCH` option for BLTouch support.
|
|
|
|
Enable the `SAPPHIRE_PLUS_TMC_UART` option for TMC UART support for the X, Y and E steppers. Note: you will need some hardware modification skills to modify the stepper sticks. A solder pad needs to be bridged to connect PDN to USART pin. Then a 1K resistor and wire is needed to connect the USART pin to the appropriate spare pin on MKS Robin Nano V1.2 board.
