Positron V3.2
The Positron V3.2 is an upgraded version of Kralyn's upside-down, foldable, tiny CoreXY printer that conveniently fits into a filament box! Collaborating with the Positron team, LDO has dedicated the past year to optimizing the kit, ensuring it is easy to assemble and yields excellent results. The kit incorporates high-quality components, such as genuine Gates belts, an included Raspberry Pi-based screen, and a highly transparent ITO glass heater bed. We also upgraded the filament box to a hard case for easy and safe travels! Available early 2024!
