SO SORRY GUYS !!
I had mixed up inputs, all now sorted out as regards inputs. Float is 003 !
But there som other issues with float head.
Z is homed that is all the way up.
When I run circles from extras it goes to my commanded X/Y 200
Nothing happens, waiting for Z to move down and trigger float head
If I manually touch so float head triggers Z starts to move in wrong direction!
Z is moving UP with PgUp key just as I want it to do.
So where do I change Z axis movement after trigging float?

I do not get this, sorry old mans brain fart 
Home works = Z moves in correct direction.
Run a circle = it moves out and stands still, manually touch float >>>> Z moves the wrong way UP it should go down.
[AXIS_Z]
MIN_LIMIT = -20
MAX_LIMIT = 85
It does not matter what I do neg or pos numer or change position (Yes same on Joint)
Pls give this old fart a pointing finger what to do.

Hi Clive,
That sends Z in wrong direction, have been testing all combinations and no go
Home works as it should = lifts the axis UP and away from workpiece.

Ok that is probably because of the motor wiring which is fine so the numbers would need to be reversed
re mine;-
HOME = -5 this moves home down by 5mm
HOME_OFFSET = 1
HOME_SEARCH_VEL = 10 this sets the speed to search mine is +ve but changing it to -ve woul reverse the direction of travel
HOME_LATCH_VEL = -2 changing the sign will reverse the direction
HOME_FINAL_VEL = 5 this is the speed
HOME_SEQUENCE = 0
HOME_USE_INDEX = False
HOME_IGNORE_LIMITS = True
When you jog down does it show a -ve number on the dro ??
when you home to the top then you have to move the axis down to just below the slats and touch off then move the axis back near the top then never have to touch off again
your showing max limit as a +ve number
