Hi Alwyn,
also the short version has the same problem.
Before the clamp can be tightened, the gap is completely closed.
I used the angle grinder to remove about 1mm from the clamp.
Now, fully tightened there`s a gap appr. 0.5 mil. And the DMD2 865X does not move, even after a road paved with cobblestones.
I made a notification to Thork via my dealer in the Netherlands.
Hopefully this will work for your long version too.
