Hi @harardror,
I wasn’t able to find a G-code parser in the database of XOD libraries (https://xod.io/libs/). Creating a G-code parser and motion control system is not trivial. For example, if you want smooth acceleration/deceleration and cornering you will need an algorithm that can look ahead and plan movement. If you are looking for software that will run on an Arduino, but don’t necessarily need a XOD solution, I can recommend grbl. I’ve used grbl in one of my own projects.
