The OLSK Small CNC V3 is a desktop CNC milling machine with an innovative open-source tool changer, one of the first in an open-source machine.
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 logical order to provide a smooth assembly.
