Solved - Panet CNC TNG Toolchange keeps hitting limit switch after tool measure

hi everyone, i hope you can help me, I am trying to get the toolchange sorted on my little cnc machine. So far the machine sops when it comes to a tool change in the way that I want, it moves to the front corner of the machine and raises to just before the z limit switch so I have plenty of room to change the tool. The program is now in pause mode. It lets me remove and change the tool as well as jog the spindle back to the part so I can do the tool z measure. After i have measured the z value I then go to press pause to resume the program and the z axis raises all the way till it stops on the limit switch.

Not sure if im making sense but I will try and get a screen shot of the tool change settings now, Any help would be most appreciated as im so close with this but falling over at the last bit
