Experimenting with CNC Dovetails

December 5th, 2010 by otto_pjm

I’ve had a wizard to do Dovetail joints for awhile and never had a reason to use it until now. We need some drawers built for an odd sized cupboard, and as you may know the HF recently received a pallet or two of drawer sides as a donation. So it seemed like a good time to check out the wizard and try and make some drawers.

Here’s a shot of the setup,



It’s kind of a pain as you need to operate on the edge of the board. I built my latest table in two pieces so I could do dovetails and put the 4th access I hope to build under that part of the frame.

CNC Router Operator – Check-out class 12/12 9-Noon

December 4th, 2010 by otto_pjm

Due to the weather the class will be rescheduled sometime in January. The User Guide is ready for review, I’m trying to figure out how to get it posted at the moment.

This class is primarily targeted at TC Maker member, who wish to use the CNC Router. The intent is to give practical step by step use and operation instruction. The public is welcome to attend, but due to the focus on one specific system and the time limitations general questions about CNC systems and tools will only be addressed as time allows.

CNC Router user operation training class, allows you to use the router to work on your own projects

The HackFactory

Sunday December 12th from 9:00 AM to Noon.

What you’ll need:
Nothing really, you may want to take notes, (I hope to have a rational step by step guide put together, but holes will certainly exist) also laptop’s (or classroom PCs) with design tools to create 2D or 3D object maybe useful. (formats such as EPS, dxf, stl, etc)

Non-members and those interested in CNC, but not wishing to run a CNC Router

I intend to have additional Cut, Turn and Burn classes in 2011, and these are the forum for general questions and will deal with the end to end process turning ideas into physical objects.


Cut, Turn, and Burn – Ideas to 3D objects, Sat. Oct. 16th

September 30th, 2010 by otto_pjm

Cut Turn and Burn Banner

A Class Featuring 3D Printing on the MakerBot, CNC Routing, CNC Lathe turning, and possibly Laser etching will be held on Saturday October 16th from 1-4 PM at the Hack Factory.

Please Register on Eventbrite so we can plan accordingly.

Bring your ideas, CAD files, pictures, and questions. The class is open to everyone. For non-members, a donation of $5 to cover materials is suggested. We will strive to make the class relevant to the interests of those present. The class will include an overview of basic creation of g-code files, (The instructions that the CNC systems understand) by various means in the classroom, and demonstrations of how the various systems interpret the g-code to produce objects.

The intention is to keep things as interactive and hands-on as possible, if you have electronic media with your ideas, pictures, cad files please bring them. If you have CAD software (anything that can produce a dxf file), Vector Graphics Software (Illustrator, Inkscape) or 3D Design software (anything that can produce an stl file) on a laptop bring it along.

We’ll do our best to get your ideas into your hands, please be aware that the materials, tools, tooling, and time available may not allow us to produce all items.

[Update] Pyrodogg, took some great pictures during the session, check the TC Maker flicker group for more.


Hacking Up a Laser CNC

September 3rd, 2010 by otto_pjm

We have been working on converting a CNC inspection machine into a CNC capable of using multiple tools.

CyberOptic CNC

The Y axis is only supported on one side, so the tools will need to be light unless, we can devise another support. At our last open house on Wednesday, we had a great hacker collaboration and not only got the machine to draw with a Sharpie, but trying some engraving with jtbarclay’s blueray burner. Here’s a shot of the engraving in progress.
