Once again, we've got a user who has really impressed us (this is becoming really common). Marc, one of our earliest users, just posted a thread in our forum showing his process for milling PCBs and the results.
Check out the thread here: http://community.carbide3d.com/t/great-results-milling-pcbs-from-eagle-with-the-nomad/
We know that lots of users are interested in making PCBs with their Nomad and Marc's thread has almost everything you need to get started.
