README
README.mdDescription: Its a polar, 4axis, cantivileerian 3d printer! It uses a unorthodox aproach to rotate the hotend in b axis, and y axis, using only 2 motors and being pretty cool! The printbed is also backlit!! :3 WHy? idk, felt like it tbh. Saw a cool video on yt, thought: i wanna do that. And then highway happened. And then this happened.

Questions
How big is the Boop PCB?
It measures 188 × 126 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Boop use?
89 parts, built around the AZ1084CD-5.0TRG1 and WS2812B. 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 Boop KiCad files?
From the Magicninja7/Boop repository on GitHub, at the commit this page was made from: the board is pcb/boop.kicad_pcb and its schematic pcb/boop.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Boop design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
