If HOME_SEQUENCE is not specified then the joint will not be homed by the HOME ALL sequence (but may be homed by individual joint-specific homing commands).

Immediate Homing If a joint does not have home switches or does not have a logical home position like a rotary joint and you want that joint to home at the current position when the "Home All" button is pressed in the Axis gui, then the following ini entries for that joint are needed. HOME_SEARCH_VEL = 0 HOME_LATCH_VEL = 0 HOME_USE_INDEX = NO HOME equals to HOME_OFFSET HOME_SEQUENCE = 0 (or other valid sequence number)
