+# 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. 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).
+* Checkout 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.
+* 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!
