About this project

Help me upgrade my license to Eagle PCB from version 5 to version 7.  In return I will share my modified ULP script that allows PCBs to be exported to GCode and run on home CNC machines.

My updated GCode script is based on exiting well tested scripts and adds a number of features such as different milling layer for making unique shapes and being able to route double sided boards on a home CNC machine.

The ULP script is documented and clearly readable, providing for a great foundation to learn ULPs or modify for your own use.

Here is a screenshot of the GUI where you can select the options for routing on the CNC, including mounting holes for routing both sides.

 If there is enough interest I plan on adding autoleveling where the PCB is probed to determine the Z height before routing is done, this way the routing height is consistent. 

Be able to make home PCBs like this:

Risks and challenges

Very few risks, the script is functional and I use it all the time to make parts and adapter boards.
