A community of designers, engineers and artists.
Our mini CNC conference yesterday was a huge success thanks to InGenius and Doug.
Doug’s notes: Getting Started, CNC Overview
Also we had an amazing surprise appearance of Micah Black of A2DElectronics.ca and a laser cutter that he built. See images below. Also he has a build article.
Here’s a video:
Blink CNC is a group CNC build within the hack613 community!
The fist challenge is to build a drawing machine based on this electrical kit.
Two of these steppers with controllers ($3.88 CAD)
One of these servos ($1.83 CAD)
An Uno ($7.64 CAD)
A power supply ($4.31 CAD)
That comes out to $17.66. None of this links or prices are well researched, your mileage may vary. Many people will have an Uno and a power supply so for them this is a $5 project.
A drawing robot was chosen because it gets rid of the spindle. Also the servo can simplify the Z axis.
2) 2 AxisTwo of these steppers or these cheaper steppers. This motor shield. One of the above servos.The above Uno. Some kinds power supply.
3) 3 AxisThree of these steppers. One of these grbl boards. Three of these stepper drivers. Some kinda power supply.
4) 3 axis nema 17 kit: Parallel port based kit.Desktop computer with mach3Spindle kit.

Way back a few years ago for a short time our group was called Blink. The idea was that when newcomers came the objective was to get them to be able to run the Arduino Blink program. Sort of an initiation and also a way of welcoming new people to the group.
That was pretty successful.
Our group has made many leaps and bounds since then and now we’ve got a group build of an experimental CNC machine! Newcomers can now get a CNC machine at low cost.
We had fun engraving/carving hockey pucks last Weekend. It was like a mini-CNC-faire. We had four CNC machines onsite with a team of nine people designing and cutting pucks.
This is all thanks to Artengine, the City of Ottawa and Hack613 (us!).
A few more pictures from preparation leading up to the event.
CNC613 is a project to create a shared CNC machine. People can learn to use it and understand their needs and eventually elect to buy a machine or just use the shared machine. The exposure to the machine and community around it would lower the friction for people to buy or adopt this method of fabrication.
It was initiated by Darcy Whyte and the first machine was assembled by Doug Commons and Dave Hunt. A bit of help from Richard Sloan.
We now have a great community of practice around CNC techniques.

Joe’s CNC” design, made from MDF and conduit pipe/skate bearings for the rails. The “spindle” is just a Bosch wood router. Approximate work area is 2′ x 4′. Currently fits snugly in an 8’x10′ shed 🙂

Cutting area is about 17″x14.5″
Spindle is a 400W brushless dc motor.
Software used is linuxcnc.
