If i am not mistaking for your values and 12v psu it would take ~0.0010779930014654s for current to rise to a set level of 0.5A. On the other hand the motors from this post datasheet would need ~0.0005995044. Latter is a bit lower, but not *that* much, but still it may show when the motor needs to rotate fast. So the torque applied to the rotor depends on this current. Though once it reaches the set level if we use a constant current driver then the voltage will be chopped for the current to stay steady. Therefore if driven this way it means its not important when holding position or at slow moves, but it can become an issue at high speeds - only. Bottom line, its not ideal, but since you bought them already, lets hope for the best. Probably will work coz normally should be room between the torque of the motors and what the printer *really* needs, or otherwise you could decrease acceleration parameters. In the extreme case you want to actually change something, then you may increase the voltage from 12v psu to 24v psu and then with 24v it will take ~5.93595*10^-5 to reach 0.5A, thats even faster than the other motor @12v. Also lets say that the current setting should be really more than 0.5A though, so the numbers above (and their proportions) arent nailed to the board, just the ideea.
