CNC Snap is the place to go for a DIY desktop CNC and stepper motor drivers. We're raising the bar in inexpensive CNCs. Start making cool and amazing things.

Temporary Store Shutdown

We are shutting the store temporarily to get caught up on current orders.
Will be open March/01/2012
This will allow us to better serve future customers. Less lead time new custom parts and A new version of 3D printer is in the works with laser cutting ability. I like to call it Ceasar Pillar of Light.

C-Borg 3D Printer making upgrade



C-Borg is a 3D printer and CNC mill platform in one.
The goal is to make it as affordable as Possible Under $600.

Wiring Diagram for DC Motor + Domo*pes or Arduino + Circuit + Code

This will make your DC motor go forwards, then backwards repeatedly. It is done by using four transistors. They will split the two wires from motor and make four wires. One half is forward's ground and +. The other half is reverse's ground and +.

Supplies:
-DC Motor
-a Domo*pes or an Arduino
-4 2222A NPN Transistors from Radio Shack or wherever - be careful not to mistake for PNP
npn transistor
-Breadboard from Radio Shack or wherever
-Wire such as CAT5 or whatever
-Power Source for motor - depends on motor but somewhere around 3V probably and around 5V for Domo*pes or Arduino. So, a 9-12V 800-1000mA would be a good starting point.
-DC Move Motor Sketch for Domo*pes and Arduino

Breadboard View:
The transistor name 2222A should face you like the N in pic below when enlarged. If not, the collector and emitter will be backwards.
