I have no idea which one is better, Im using ramps 1.4 and A4988 (Black edition)
Which one do you guys suggest?
and if by any chance you know something about the voltage and amp for A4988, then please tell me how much voltage and amp (or anything else which im missing) can a A4988 driver give to each step motor.
unipolor likely will have 6 wires, or 8 wires. they can be wired up to work as bipolar. bipolar have 4 wires, and require alternating the direction of voltage. either one will work for ramps. just make sure to follow the bipolar configuration of each motor. the diagram of the motor should state what wires to use. the correct labeling of the wires to use are -a,a,-b,b
