How do I change my current setting on the stepper motor drivers?
There are 2 styles of stepper drivers that we have for the E3. Both styles work equally well, but the
current needs to be set with different values. The yellow circles denote the driver with the R200
resistors. The blue circles are the R050 resistors. Note that these resistors are in different locations.
