about 3.9. HOME_SEQUENCE the single way - wiring to one pin can be done if there will be enforced sequence --- first home X, second home Y and third home Z. To guaranty that one axis at the any given moment can be homed if so than how do that? option only 0 and 1 how to mark each axis - there are 3 or more axis ?
