A project log for Minamil: a minimal CNC mill - HaDPrize 2021

Minamil: a minimal 3-axis CNC mill that works. Build from laser-cut hardboard with a screwdriver (mostly). Mill fine-pitch PCBs.

Certainly many people have made very low cost CNC machines from scavenged parts, scrap materials, an equipped shop, and a fair idea of what they were aiming for.

This project presents a design based on two main assemblies – the X+Y axes, and the Z axis+tool clamp – built from a few specified hardware parts and some laser cut flat pieces following detailed illustrated assembly instructions.

 The frame that holds the Z axis over the X+Y axes does call for ad hoc construction from available material, but that can be made to eyeball precision from practically any rigid flat-ish material and would not benefit from over-specification.
