Finally received my FEP Film for the printer. The first item set to be printed is:

Touch-D Module:

Fully supported on Chitubox, Time to run the slicer model on Photon File Validator. This program has saved many prints from the bin as you can't always catch all the overhangs when in the slicer. 

As you can see there is always one or two unsupported parts in the slicer file which you can do the following:

1. Press the 'Fix' button and fingers crosses it can solve the issue. (this normally solves 80% of issues)
2. Go back into the slicer on the faulty layer height and add supports or rotate the model.

Time to fire up the photon and print these bad boys :D
