Make a CNC Hot Wire Foam Cutter from parts available at your local hardware store

Step 12 The Electronics

The electronics is the only part that is "kinda" hard to find.
You can search ebay and look for "4 axis stepper motor driver".
Then you will have to find 4 stepper that will match the drivers - pay attention to the type of driver you are getting. Some will work with Biploar motors and some will work with Unipolar motors.
The last step is to find a power supply. The power supply should be around 24V 5A, but its best to get all of the electronics from one source.
If you can't find anything on ebay try this

The Electronic box works together with the software you choose.
Make sure that the electronics you select can be programmed to accept pulse and direction for each of the 4 axis.
Mach3, KCAM and Foamworks will all work fine
Mach3 will only drive the electronics. Foamworks will also generate a file called "DAT" file, and with this file it will also control the electronics.

Sounds complicated, but take a look at all these web sites and after a while things will start making sense.
