@Stephen6309 thanks that did that was it. is there a reason the z babystep would not make changes before?

i have a gmax 1.5xt running a duet 2 wifi and a titan aero and bl touch
I have everything setup and working machine homes fine but everytime i start a print it prints in the air maybe 2mm off the bed no amount of z babystep or offset changes make a difference. hopefully someone can point me in the correct direction as i am new to rep rap and duet. thanks in advance below are my config and home files.
