I build the wonderful MidTBot and have been enjoying creating pen plots.

My version abuses the tiny bot by extending the linear rods to give me a drawing size of 360x240 mm.

Its brain is an ESP-32 running the flexible FluidNC which turns the GRBL into motor movements via two StepStick stepper drivers.

Plots

Mostly I’ve been doing procedurally generated pieces but I also played with 3D vectorization using Blender/Freestyle, pixel art fills, vector fills, clear layer topographic mapping (of the moon) and lots more.

You can see more in my IG or in my git repo of past plots.
