OLSK Small 3D Printer v2 is an open-source desktop 3D printer with a printing volume of 240 x 240 x 240 mm. Its rigid frame is fully composed of aluminum interlocked plates. The coreXY motion system allows a good quality fast printing of max motion at 1200mm/s at 20k mm/s2 acceleration (it prints this Prusa 3D model 2x faster than its original Prusa 3D printer). The bed has an automatic mesh leveling and Z tilt alignment and the printing surface with a non-sticking layer is removable. It also features a user-friendly interface with Klipper-based firmware, a touch screen, and a filament runout sensor for a smooth printing experience. The housing is enclosed to keep a higher temperature.
All OLSK machines are open source and have the BOM and necessary files available in this repository for replication. The assembly of parts is also documented in a workbook where each step contains a list of parts, tools and instruction remarks, following a logic order to provide a smooth assembly.
