This is a firmware for reprap single-processor electronics setups. It also works on the Ultimaker PCB. It supports printing from SD card+Folders, and look-ahead trajectory planning. This firmware is a mashup between Sprinter, grbl and many original parts.

The Marlin development is currently revived. There's a long list of reported issues and pull requests, which we are working on currently. We are actively looking for testers. So please try the current development version and report new issues and feedback.
