OtherMill (Bantam Tools) CNC Mill
The OtherMill (now Bantam Tools) is a CNC mill used mainly for milling printed circuit boards (PCBs). In the Maker Lab we have 2 OtherMill Pro machines.
Training Required: Basic Training and OtherMill Training
Workspace: 5.5 x 4.5 x 1.6 inches
Materials: FR-1 boards (machinable wax, aluminum, plastics) DO NOT MILL FR-4.
File Types: Eagle .brd and Gerber
Material Fees: We have single-sided and double-sided FR-1 boards available in the Maker Store.
Common Terminology: Traces - the flat, narrow part of copper left after milling that connects the electronic components together; Vias- the electrical connections between the front and back of the board.
Software for creating file:
Eagle (Autodesk) (.brd or Gerber)
Software for connecting to OtherMill:
DIY Arduino Board
Students used the OtherMill to machine DIY Arduino boards for creating "useless boxes". They soldered on components and laser cut the box housing.
