Alternately, a more refined manual phasing method can be implemented. Knowing a good value which
would lock the motors onto a phase (using the above procedure), the following example locks (in small
incremental steps) the motor onto one phase then steps it back into the other phase:
Manual Phasing Example 2:

Mtr1PhasePos->X:$B4,0,24,S
#define Mtr1PhaseErrBit
