New guy here...

[jure_bilic]

Hi everybody,

I'm new here and in the world of CNC. Also excuse my english, I don't live in english speaking area.

Anyway, I decided to build a small 3 axes CNC machine.
Since I primarily work with wood, CNC will be used for that purpose. I got some steper motors from old printers and I thought of building the body of CNC from wood or aluminium.

Now the problem comes to the electronics. Since I don't have access to large amounts of money, I wanted to make the breakout board and controllers by myself. But, the problem is, I can't find any schematics.

So I'm asking you if you could help me out here, give me some links, advices etc.

And apologies if there is already a similar thread, I searched but ended up with nothing :P

Hope to get some help from the experts here and to become a useful memeber one day

Greetings from Croatia

p.s
once more, sorry for the bad english

Here is a "DIY" breakout board:

Four Axis Interface ST - PMinMO.com

There is a lot of other useful information on the Pminmo.com site.

Here is an example of a DIY motor driver (for small to medium sized unipolar stepper motors):

Linistepper V2 Build Instructions

And here is another example of a DIY motor driver (for small bipolar stepper motors):

Here's one that I have built for bipolar motors...

Thanks guys, these are great. But I have a little dilemma here - I forgot to mention that these motors have only 4 wires, not 6. Do I need to change them?
Since I only need a cutting area of about 30 cm x 30 cm...

Thanks very much for the links

4-wire motors should work with bipolar stepper drivers.
