Thank you so much this was the problem, just a beginner mistake I guess.

Thank you but this is not the problem, I have it set to my printer exactly and double checked after this comment.

When I hit the bottom slider my model went grey and it will not go back to the colour preview. I have tried three different models and all of them when I try to preview layers will turn into a grey shadow. I have been looking online and all I am finding is stuff about the model being too big which none of them were. Help would be much appreciated!
