Dear Kaero
Your project looks great. Actually I am about to try something similar. Would you be willing to share some of your results?
You write about "free and open source applications are available for conversion of digital 3D objects into G-codes," and I have no idea where to search and how to start.
On the other hand I would be interested in more details, how you built it.
It would be great, if you could share your learnings.
Best regards,
Andi
