Just something to think about...unless you have a few electronic test instruments (oscilloscope, voltmeter, etc.) you'll most likely spend alot of time being frustrated if you attempt to build from a schematic...I don't know your level of expertise, but it might be simpler to buy some Geckos ($300) or one of the other stepper driver boards advertised on the site...just depends on the experience that you want to live for the next couple of months. |
