Location visible to members
The Chesapeake Area Metalworkers Society (CAMS) http://www.cams-club.... (http://www.cams-club.org). has a long-established and active CNC special interest group.
Don't be concerned if you only see 1 or 2 people RSVP here. Most group members aren't meetup.com regulars they know when the meeting is scheduled and just show up. If you have any doubts about a meeting being scheduled, contact me for more information.
CAMS CNC meets in Lorton, VA at the offices of Practical Micro Designs (pmdx.com) a manufacturer of CNC electronic devices.
The meetings are usually only 8-12 people but it is a very knowledgeable group. You'll absorb an amazing amount by attending, even more if you ask questions or bring along a project you need help with.
The members attending vary from month to month but we have people who own CNC-equipped machine shops doing commercial work, home shop hobbiests who have retrofitted traditional equipment, and several who have built their own woodworking CNC routers.
Contact me for meeting details and directions.
