Yes Dunk, i thought i had explained clearly, perhaps not. I have the instructions for collimating the focuser, and have years of experience collimating focusers. The adjustments work, i can align the focuser at any particular point on the scale, even at the Edge back focus point of 133.35mm; the issue is any movement of the focuser draw tube position ruins collimation, rack in collimation out, rack out collimation out. With a laser in the focuser i can see the dot move diagonally above and below the centre target of the corrector when racked in and out, it will not hold the centre. Nothing in the range of adjustments will allow it to hold the centre when moved. So i have removed it all together, and the scope has stable collimation now using just the standard mirror movement focuser. I don't know how to explain it any clearer.
