CNC Interest Group meet-up

June 5th, 2015 by otto_pjm

We will be having the first, of what I hope will be many, CNC Interest Group meet-ups this Sunday 6/7/2015 2:00 PM at the Hack Factory. It is open to everyone, but machine use requires membership. The agenda is rather loose, but will likely include, updates on the CNC area, the status of the 4 CNC routers at the Hack Factory. Information on how you can get checked out to use the CNC Routers.
We’ll also be plodding through some of the lovely features of Autodesk Fusion 360s CAM module, and have some cutting demos.

If you have been wanting to get a project cut on a CNC or get checked out on the CNC machines, this is where you want to be to get the process started. Hope to see a good group of folks Sunday.

CNC Projects? Show us yours!

May 16th, 2013 by otto_pjm

Following the most recent CNC Class, which I think was a great success on many levels, I was inspired to make a project that has been on the back burner for awhile. I want to use a CNC to make some furniture. I’ve been inspired by the work of Gregg Fleishman, and as a starting point I cutout a scale model of one of his designs.

CNC Checkout and Intro to CAM Class

April 26th, 2013 by otto_pjm

Routing a skateboard mold

Learn how to use a CNC router to cut 2D and 3D objects out of a variety of materials. TC Maker has 3 CNC routers available at the Hack Factory, come and learn how to use them and start making your own awesome stuff!

The class will have two parts (Machine Check-out, and CAM gcode creation) with the machine introduction and check-out scheduled for 1pm – 5pm Saturday and the CAM workshop from 10am – 2pm on Sunday.

Intro to CNC Class Sign up here. It’s $45 for the 2 days of class

Intro to CNC and CAM class

January 17th, 2013 by otto_pjm

Routing a skateboard mold

Learn how to use a CNC router to cut 2D and 3D objects out of a variety of materials.

The classes will be held on February 2nd and 3rd. CNC Introduction and Check-out on Saturday, and CAM / gcode creation on Sunday. The schedule will be 10am – 4pm both days. Intro to CNC Class Sign up here. It’s $25 per class / day or $40 for both classes.

VERY IMPORTANT! if you want to be able to generate your own gcode (so you can cut out something you want) you will need to take both classes, The CNC introduction class is just to demonstrate safe and proficient use of the machines, and everyone will be cutting a pre-selected file that I have prepared. To cut your own creations you will need to take both classes,


Intro to CNC
, CNC overview and safe use check-out

Attendees will be provided a 2D gcode file, and need to demonstrate proficiency, by safely cutting the part on the machine.

  • Saturday morning: Use and safety training on the machines ( class room, then with the machine(s) )
  • Break for Lunch
  • Saturday afternoon: individual user check-out on the machines


Intro to CAM
, 2D and 3D Computer Aided Machining (CAM)

Attendees will be given an overview on how to use 2D and 3D CAM software to generate the gcode or tools paths that the CNC machines use to cutout parts. Please see the important notice below on how to acquire the software before class so you are ready to go!

  • Sunday morning: gcode creation for 2D, and 3D objects.
  • Break for Lunch
  • Additional instruction, likely classroom and shop.
  • Sunday afternoon: individual help with gcode creation, user check-out for those who couldn’t Sat afternoon and cutting of files for the code creation group.

CNC Lithophane, 1st try

October 5th, 2012 by otto_pjm

I’ve been wanting to try this for sometime, and finally had my setup mostly ready and the right materials. A Lithophane is an image etched into something translucent. In my case I used LinuxCNC, which runs my CNC router, and includes a script called Image-to-gcode, that creates a gcode height map based on the color or light to dark variations in an image. The material I used is 1/2″ Corian.
The original picture is this one of my son at the beach.
