Server Details

Whether you're new to 3D printing, designing a motion system that needs a user interface, or an experienced 3D printer enthusiast who needs to modify Marlin Firmware for your needs, this is the Discord for you. This Discord server was founded by Marlin lead developer @thinkyhead as a place for contributors, patrons, sponsors, users, and companies who use Marlin Firmware to get familiar, help one another, and share ideas to improve 3D printing and keep the RepRap project moving. As we go forward we face many challenges to relevance and funding in a constantly evolving industry. But there is no shortage of work, both in clearing up everyday issues and in preparing for the next chapter in single-processor 3D printers. The 3D printing and maker community does so much to breathe life into this challenging project and keeps us all motivated, so join up and become a part of the movement!
