# Installing BLTouch-compatible firmware onto the TwoTrees Sapphire Pro
|
|
|
|
I installed a BLTouch/3D Touch probe onto my TwoTrees Sapphire Pro, and configuring the firmware was a bit involved. The Sapphire Pro has a MKS Robin Nano v1.2 board. Here's the process:
|
|
|
|
* Clone the [Marlin repo from GitHub](https://github.com/MarlinFirmware/Marlin).
|
|
* Download [the configurations](https://github.com/MarlinFirmware/Configurations/archive/bugfix-2.1.x.zip).
|
|
* Check out the `2.1` branch (the configurations seem to be tailored to it and I couldn't be bothered changing).
|
|
* Replace the `Configuration.h` and `Configuration_adv.h` files with the ones from the configurations zip.
|
|
* Uncomment the `SPRO_BLTOUCH` define.
|
|
* I also changed my dimensions to `X_BED_SIZE 230` and `Y_BED_SIZE 225`, for a more realistic bed size.
|
|
* Enable Universal Bed Leveling (replace the `AUTO_BED_LEVELING_BILINEAR` define with `AUTO_BED_LEVELING_UBL`), as Bilinear was terrible for me.
|
|
* You can also enable the Repeatability Test command with `Z_MIN_PROBE_REPEATABILITY_TEST`.
|
|
* Build with `pio run -e mks_robin_nano35`.
|
|
* Copy `.pio/build/mks_robin_nano35/Robin_nano35.bin` to the SD card.
|
|
* Insert the card into the printer and turn it on.
|
|
* Done!
