====== Pencil Plotter ======

Project initiated May 2021. 

Probably going to start with Andrew Sleigh's v3 design of pencil plotter and improve from there if I need to.

  * 2 NEMA 17 motors
  * 2 GT2 timing belts

  * 30 or 40 tooth pulley for x-axis timing belt
  * 20 tooth pulley for x-axis timing belt
