I have 4 DL3 in Action On of them is more slower than the other All have the same Version, 1.5.2 This fixture seems to have a trouble on re positionning
Problems I have seen in my DL3 before are on the silver tilt wheel there are three black hex screws that hold it in place and on mine they have become loose and I have to go through about every 2 months and re-tighten all those screws. Another problem I have seen in the past is that you could also have a bad encoder wheel or sensor which could be checked by if the fixture has proper feedback.
