Lasers... Yes they need to be checked for collimation too. One cant simply rely on the manufacturer. Maybe Howie Glatter ones are ok.
Looking at the OCAL website and the SCT coll video this system isnt a laser but rather its more a virtual set of circles like AlsCollimationCircles but with crosshairs thrown in.
It looks like the secondary in the video is rather loose at the start, so maybe you should loosen your secondary as per a restart.
