/**
 * M906: Set motor current in milliamps.
 *
 * Parameters:
 *   X[current]  - Set mA current for X driver(s)
 *   Y[current]  - Set mA current for Y driver(s)
 *   Z[current]  - Set mA current for Z driver(s)
 *   E[current]  - Set mA current for E driver(s)
 *
 *   I[index]    - Axis sub-index (Omit or 0 for X, Y, Z; 1 for X2, Y2, Z2; 2 for Z3.)
 *   T[index]    - Extruder index (Zero-based. Omit for E0 only.)
 *
 * With no parameters report driver currents.
