General Mach Discussion / Re: DC Motor as Rotational axis

No, the relay was mentioned just because you said "one for each direction of movement" about the two wires. So I was thinking if you had a double pole double throw relay you could reverse the direction. You would not have any control over it except you could vary the supply voltage to control the speed and reverse the direction.
For positioning as you would such as with an axis you would need proper control over it by turning the DC motor into basically a servo and that is where the encoder and drive would be required.
