Hardware

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.
