If the motor becomes too hot it means your current is too high. The minimum current required is that just (about 10 to 15 percent) above the point where it starts to miss steps under your normal load. Any more current will just be wasted as heat in both the driver and motor and may actually cause it to run rougher.

No, microstepping on 2130's (V1.1 and higher) can only be configured through SPI.
OK. I try to further reduce the motor current. But as a stepper in the RA AXE the same engine supplies 0.67V and was not hot. The driver "DRV8825" also is not to hot...?
