Millennium Machines Milo V2 CNC Mill Kit

Milo V2 is the next evolution of the open-source desktop CNC mill from Millennium Machines. It builds on the OpenBuilds MiniMill concept with improvements to the size, rigidity, and customization. Designed for DIYers, the Milo V2 can cut soft metals like aluminum and brass, as well as steel if you're smart about it, while also excelling at composites, wood, and plastics.

Open-Source Desktop CNC Mill

Milo V2 is a capable desktop mill without the proprietary black box. This LDO kit includes the parts to build it, with full documentation from Millennium Machines. It cuts a wide range of materials and can be maintained with hand tools instead of a service contract.

What Changed in V2

• Bigger work area. More travel across the bed than the V1.5, so larger parts and longer stock fit in a single setup.
• Redesigned plates. The structural plates have been reworked for a stiffer machine and a more straightforward build.
• Simple tramming. Squaring the spindle to the bed is quicker to set and holds better, which is reflected in the surface finish.
• Magnetic way covers. They lift off by hand for cleaning, then snap back to keep chips and dust out of the motion system.
• Auto-adjusting anti-backlash nuts. They take up wear on their own, so the machine holds its accuracy through months of cutting.

What Can It Cut

Steel and Harder Metals

Steel is on the table with conservative cuts, sensible feeds and speeds, and a carefully assembled and trammed machine. The part shown is 303 stainless.

Aluminum and Composites

Aluminum is everyday work for Milo. Grades like 7075 machine cleanly, alongside composites such as carbon-fiber sheet and G10 for brackets and enclosures.

Wood and Plastics

Hardwoods, plywood, MDF, and plastics like acrylic and Delrin are easy work for prototypes, fixtures, inlays, signage, and enclosures.

Open Source

Milo V2 is fully open-source under the GPL-3.0 license. The full CAD, bill of materials, and assembly manual are all published on GitHub, so you can build it, modify it, and source parts from any supplier.

Milo runs on RepRapFirmware, with an optional MillenniumOS add-on for guided probing, toolsetting, and tool changes. Development is public, with an active community on Discord and Reddit.
