This is the hardware (and firmware) repo for the hotplate, an automatic, fully printable toolchanger for cnc machines. It's ostensibly part of the clank machine platform, but you could probably stick it on anything. Or reference the design patterns, and stick the idea on anything.
Read the dev log for updates, and you can find the most up to date CAD in /cad. Associated circuits are in /circuit and their firmwares in /firmware. Some of the firmware stuff is still private (submodules) so cloning might be troublesome at the moment, just download the zip.
More extensive documentation is online at clank.tools/tools !
This repo is mirrored on github and the cba internal gitlab.
