Hello,
i also didn't want to give up my octoprint surface, so there is a small PI Zero hanging in my Mars.
The UART of the PI hangs directly on the UART of the printer.
The Pi also hangs as "Flash memory" on the mainboard. At the USB cable I have cut the positive line for safety reasons.
The Pi is powered by a buck converter from the 12V of the printer. Next I want to control the main power supply of the printer with the PI.

The printer communicates with 3.3V and 115200 Baud via the Uart.

My TODO`s:
- control Mainpower
- a heating element controlled by the PI
- Maybe I will try to adapt to Octoprint at some point.
