Questions
How big is the Controller PCB?
It measures 144.8 × 104.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
66 parts, built around the 74HC165D and A4988. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Controller KiCad files?
From the phorton1/Arduino-cnc-cnc3018 repository on GitHub, at the commit this page was made from: the board is docs/kicad/controller/controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask phorton1 before reusing the design.
