| Board | Common Version | Best Firmware | |--------|----------------|----------------| | MKS Robin Nano V1.2 / V1.3 | STM32F407ZG | Marlin 2.1.x (preconfigured) | | MKS Robin Nano V3 | STM32F407VGT6 | Marlin 2.1.x or Klipper | | MKS Gen L | ATmega2560 | Marlin 2.0.x | | TwoTrees stock board (green) | STM32F103 | Marlin 2.0.x |
Klipper is frequently cited as the single biggest "quality of life" upgrade for this machine. It offloads complex calculations to a secondary host like a Raspberry Pi, allowing the Sapphire Pro's CoreXY motion system to shine.
