Updated at 2026-10-28

This specific model in the catalog emphasizes its open-source motherboard, which is compatible with various firmware updates. It offers a large build envelope of 300 by 300 by 400mm, making it one of the larger options for desktop FDM printing. The machine is mostly assembled in the factory to reduce the technical burden on the user.

The inclusion of TMC 2209 drivers helps the printer operate with less noise and improved precision. It features a dual-slope support rod design that creates a stable triangular base, which is important for maintaining accuracy when printing tall objects. The user interface is designed to be intuitive for navigating files and settings.

This unit is built to handle long print jobs with its resume function, ensuring that a temporary power loss does not ruin hours of work. The glass bed provides a flat surface for the first layer to adhere to. It serves as a versatile tool for makers who require a significant amount of vertical and horizontal space.
