If you are looking to upgrade your machine, here is an informative guide to the best firmware options currently available for the Two Trees Sapphire Pro.
Check the board to see if it is a Robin Nano V1.2, V1.3, or a newer version. two trees sapphire pro firmware best
If you need custom settings like BLTouch support or modified dimensions, it's best to compile your own firmware:
A. The Best Overall: Custom Marlin 2.0.x / 2.1.x (Modified for MKS Robin Nano) It is Klipper running on a Pi, tuned
Klipper is, for many, the ultimate firmware upgrade. It takes a different approach by moving the computational heavy lifting to a more powerful companion computer (like a Raspberry Pi). This allows the printer's mainboard to focus on the simple task of moving stepper motors, resulting in incredibly smooth and fast prints.
Klipper offloads the heavy calculations from the printer's MKS Robin Nano board to a Raspberry Pi or similar host, allowing for significantly higher print speeds without losing quality. Check the board to see if it is a Robin Nano V1
If your extruder or axis motors move in the wrong direction, invert the appropriate dir_pin setting. In Marlin, this is done in the configuration file. In Klipper, simply add a ! before the pin number.
