esp_set_master_initial_position() sets master initial position. This API function call
enables the user to define the master axis' initial position thereby eliminating the initial
'jump' that may occur in the slave axis as it begins slaving.
esp_get_master_initial_position() reports the present master initial position setting.
The controller defaults to normal (non-master/slave) mode after system reset.
