Any ELS requires mounting a motor and encoder first. Overall I recommend using 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.
For H2, there's an imperial version of the software for users who mostly work with inches / TPIs at https://github.com/gstwrt/nanoels-imperial.
- Questions: please open a new GitHub Discussion
- Successful/failed builds: please file a GitHub Issue with explanations and photos
- Code changes: to maximize the chance of your PR being accepted, discuss the planned change beforehand
- Only make the necessary minimal edits
- Run in the
TESTmode, add new tests if needed - Split unrelated changes into separate PRs
- PCB changes: please open a new GitHub Discussion
- 3D models: in most cases, don't edit the model, add a new file. PNG preview and a dimension would be nice too.
If you're willing to manufacture this device and/or sell it as a kit, we'd be happy to link to your page for free - especially if it makes the build cheaper than buying all the components separately.
