Hi Sweep, I thought I had sorted out the creep but it started again. Decided to take the LYNX08 unit out of the base unit and mount it in a separate box with its own supply to see if that cures it. I'm a bit concerned as once when it crept one if the red warning lights came on on the Z axis drive. Denford did some strange things to make the spindle lock in the correct position for the tool changer so I;m being carefull, Will keep you posted. putting in M5 S0 didn't solve the problem or the debounce alteration.

Ok think I have sorted it, My LYNX08 spindle board had a capacitor blown on it, I was told it made no difference to the drive unit, that was true, however I had the caspacitor replaced and all seems OK.  AT THE MOMENT!!!!
