Questions
What parts does the Prototype use?
49 parts, built around the TEENSY 4.1, IRLZ44N and SS54. 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 Prototype KiCad files?
From the lpender3672/3D_printer repository on GitHub, at the commit this page was made from: the board is cad/pcb/prototype/prototype.kicad_pcb and its schematic cad/pcb/mainboard/hmi/hmi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prototype design in my own project?
Its repository states no licence, so its author keeps all rights: ask lpender3672 before reusing the design.
