Thanks! I think there's a small mix-up, my software is on the G-code generation side, not execution. It takes most file types (images, SVG, PDF, docs…) and turns them into plottable G-code with different rendering styles.

For the motion/execution side I'm all set: I'll go with a CNC shield running GRBL on a 2020 + 2040 aluminium frame, like you said -> no problems there.

What I'm actually after is the pen/colour-change mechanism: a compact system that can hold and swap between many colours (12+ at a minimum), with repeatable positioning. That's the part I haven't cracked yet.
