Currently not working on this, not sure if I will continue this still.

To teach myself more about electronics, as well as to finally step into the world of stepper-motors I would like to try to make a plotter. Since I don't know enough yet to completely design one from scratch, it will be build after Ben's PlottyBot as he did an excellent write-up on how he did his. It also has limiter-switches for homing and a servo that can move the pencil up and down, as well as an adjustable pen holder.

Right now this project is still in an "can I?" and "sourcing parts" state.

Note: I'm not including the raspberry pi zero in the part list because I still have one laying around.
