As far as my knowledge of this printer goes:
- It runs a modified version of Klipper.
- It is not compatible with the main line Klipper version.
- Rooting only allows you to experiment with additional components, not Klipper itself.
- You are mostly limited to what the manufacturer provides.
- Experimenting with Klipper itself could have unintended consequences, including catastrophic failure.
