Two Trees Sapphire Configurations
This folder contains two default configurations for the Two Trees Sapphire Plus V2. The V2 has Dual Z Axis limit switches, and the V2.1 has a single Z limit switch, as well as a different board.
Supported Versions
| Version | Board | Z-axis switches |
|---|---|---|
| V2 | MKS Robin Nano V1.2 | 2 |
| 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.
Configuration differences on V2.1
- Build with BOARD_MKS_ROBIN_NANO_V1_3_F4;
- Disable ZMAX plug (Z increments lower the bed);
- Enable INVERT_Z_DIR (Z increments lower the bed);
- Disable PRINTCOUNTER (not supported with current settings);
- Rotate TFT 180º;
- Enable endstops always on;
- Disable multiple Z endstops;
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.
