    This command sets and/or reports the Linear Advance K factors.
    Setting the K factor to 0 disables Linear Advance.
    With the EXTRA_LIN_ADVANCE_K option Marlin maintains two slots for each extruder. The first slot is set with K and the second slot is set with L, then select the first using S0 and the second using S1.
