protocol for developing my own printer firmware?

I am planning to use Kisslicer and octoprint to send gcode to my printer. but I am going to develop my own firmware for AVR Atmega 128 chip to drive step motors according to the movement vectors that OctoPrint passes to firmware through serial port.

I have looked for the the protocol to parse the commands that is sent by octoprint, but I couldn't find a documentation. I believe there is a common protocol so that firmware and driver software can communicate.

If there is one, could you please share the link to that documentation? thanks.

You mean this?

Why do you do your own Firmware and don't just modify one of the existing firmwares?

I was just curious how those firmwares are developed.

Thanks for your reply
