Controller can be built from generally available components or from the official kit:
Apart from controller, any ELS requires mounting a motor and encoder. It's suggested to use STEPPERONLINE CL57T closed-loop driver with NEMA 23 3NM motor or stronger. If you use some other driver, make sure it has 200 steps per resolution mode, most start from 800. See hardware.md for more info.

- Successful/failed builds: please start a new GitHub Discussion with photos and comments
- 3D models: in most cases, don't edit the model, add a new file. PNG preview and a dimension would be nice too
