Now, I understand that most normal CNC require 34 size stepper motor. But at this time I want to use this (http://www.compucanjes.com/products/view/14268.html) stepper motor to make a small CNC machine yet. So I have found this (http://www.cecs.csulb.edu/~hill/ee347/Bipolar_Stepper_Motor_Lab/images/EXTERN_0009.png) circuit to drive this small stepper motor. Now I have 24V, 1.7 Amp power supply adopter and +5VDC logic supply from computer power supply. Now I want to ask that is it a good power supply to connect with this ULN2003 circuit? If not, then which is batter power supply?
