Found in the visualizer after post process completed the writing that the Z Axis at the start of the program was set as below:

G53 G0 Z90

This is wrong as the limits for my Z as it is only 88 so the process file is incorrect and needs to be adjusted to Z88, You can edit the post process file and search for Z90 there are 2 instance's where it applies the Z Height you just change them both to the same height that is listed in your machine specific section under Machine working area as mine is a 750x750x88 the Z is going to be 88 as long as this matches your height this should alleviate any issues.

Found out by trial and errors over 5 very stress full days and failures and now works first time every time.
