The original design files contained within this repository were backed up from http://devel.lulzbot.com/electronics/dolores/ on Sept 8, 2021. In case that gets taken down as well, please see this archive.org backup as well.
This repository acts as a backup to that original design (which was sadly removed from all other Lulzbot servers) while complying with the original CC BY SA 4.0 AND GPL v3 license.

Questions
How big is the Z Brake PCB?
It measures 47 × 47 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Z Brake use?
28 parts, built around the EC2-24NU. 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 Z Brake KiCad files?
From the Project-R3D/Z-Brake-Board repository on GitHub, at the commit this page was made from: the board is Z_Brake/Z_Brake.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Z Brake design in my own project?
Its repository states no licence, so its author keeps all rights: ask Project-R3D before reusing the design.
