Third-party software
Community projects that talk to NIIMBOT printers. None of them are affiliated with NIIMBOT, and listing here is not an endorsement or a review: the table records what each project says it is, so you can pick one and judge it yourself.
Note
Model support varies a lot between projects, and a project that names your model may still behave differently on your unit.
