- A CNC mill used for PCB Milling
- Can't make as small of traces as a lithography+ethcing system, BUT it is far cheaper and easier to use (ie no chemical etchants or photoresists needed)
- Uses the D3D Univeral Axis

Note on CAD Procedure and Organization:
- Draw a frame piece, and create a complete frame made of 6 of these pieces.
- Save file: File:D3D 13" Frame.fcstd
- Begin the design by downloading the X axis - File:D3D 16 Sub-assembly X Axis.fcstd
- Correct the length of the axis to 11" length (for 13" frame - 1" shorter on each side to accommodate mounting on the Y axes). Rotate the axis such that the orientation - when looking according to the Viewing Direction and XYZ axis orientation of Slide 1 in Working Document - is that the motor is on the left side of the axis (note that the orientation shown in First Slide in the Working Document has the motor on the right hand side, which is not correct).
- Save the file as File:D3D Circuit Mill X Axis.fcstd once the length is 11" and orientation is correct. This will be the file you can use later for the x axis (2 of them) to merge into the final assembly - with the second x axis being a mirror image.
- Now create the Y axis according to the orientation convention of the First Slide in the Working Document. This axis should be 13" long.
- Save the y axis file as File:D3D Circuit Mill Y Axis.fcstd.
- Now create the Z axis as in the working document. This axis can be 8" long - as we don't need a lot of z travel.
- Save the Z axis file as File:D3D Circuit Mill Z Axis.fcstd.
