Jubilee Plotter Tool
An actively-driven pen plotter toolhead for the Jubilee project.
Limitations!
My machine's "ooze control assembly" is placed significantly lower than on a standard Jubilee, so I have enough room to mount the motor/pulley assembly on the top bar, directly under the tool dock. In that configuration, a stock 600mm spring guide is comfortably long enough to cover the full build area. However, on a stock machine that requires the motor/pulley assembly to be mounted on the lower extrusion, a longer (650mm?) spring guide is probably a good idea.
At the moment, I'm using a silly large stepper motor - this design is probably compatible with a smaller "pancake" style stepper, but that is untested at the moment.
Printed Parts
Print one of each stl in the meshes folder in PLA using the standard Jubilee settings and the provided orientation. Or not, you're a responsible adult and can choose part orientation and printer settings.

Nope, not yet. Ask me on discord - maybe I'll take more photos of the pulley wire routing?
