I am hoping there is a simple fix and it's a setting somewhere, I am using Repetier host and the preview of the part shows correct on the bed but parts print back to front is it possible I have the x and y axis both the wrong way round?

not both axes, but probably just the Y axis. A lot of people wire the Y axis backwards, but the correct position of the Y axis when at the 0 position is for the bed to be completely towards the back. This puts the print head at the front where Y = 0. When you move the Y axis in a positive direction, the bed should come forward. This is changeable in the firmware by inverting the Y axis.

Spot on, it was the Y axis, I am used to my CNC where the tool moves not the bed, I set it up with bed travel not head travel, the thing is I have been using it for a couple of weeks and it only came to light when I tried to print text.
thanks mate all sorted.
Regards.
