Clank-LZ is a variant of the Clank machine family, downsized and simplified to serve as a PCB Milling machine.
We built 30 kits for this machine for How to Make Almost Anything in 2020, so that electronics design and production could be taught remotely. Read my reflections on that adventure here
This involved developing a strong set of documentation for the machine, so you might be able to build one as well. The repo is the best place to start for this.
