No, the motors are supposed to be any value 4-5 times lower than 12v. For example motors labeled 2.56v, 3v or 4v will be ok when supplied with 12v. If the stepper motor label says 12v and you supply them also with 12, thats not good: it may work, but poor performance.Quote

I get that it doesn't effect the torque but when I set the values really low like 20 the motor will move and I wont be able to stop it like I could before. It has the torque that it should instead of the puny barley moving nonsense. Which is weird I don't see how it makes a difference, maybe has something to do with the motor needing more steps or the steps are screwy? Could this be a problem with my ramps or mega board? My motors are 12v aren't they supposed to be?
No, not weird, actually its normal, if you set steps per unit small values like 0.1 and you order small moves, it will move an imperceptible distance or wont move at all. Because said value is supposed to be bigger. Thats normal.Quote

This is what is really weird, if I set it super low all of the larger values like 1,10, and 100 will work(and like before it has the torque that the motor should) but the lower value like .1 will not move the plate... well it will but the plate wont move at all until I hit .1 like 3 times and then it budges once the same distance as the 1 jog. But if I set it higher then the motor will either not move at all or will only move on the .1 jogs and make high pitch noises for all the other values increasing in pitch the higher you go in jog vale 1,10,100. weird right?
And the noise changes because of microstepping changes the coils, one coil is at some% and the other coil is at other% sort of speaking the coils are "fighting" each other in order to balance the rotor somewhere in between them. Again, normal.
