I'm using a 12" Diablo 80 tooth blade, model D1280x. I looked it up and it says it is at 15 degrees.
Model # D1280X
Diameter 12"
Machine Use Miter & Slide Miter Saw
Application Fine-Finish
Teeth 80 Hi-ATB
(Alternate-Top Bevel)
Arbor 1"
Kerf .118"
Hook Angle 15°
If this is not a good blade to use may I ask what you are use or suggest? Thanks

OK now I am on the right one...I still don't like that blade, because these are miter saw and anything more then a 5 degree hook angle positive or negative can cause some problems, because for all the fancy stuff these saws do, they are still basically a chop saw. I agree with anything more then 60 tooth is really just wasting your money. For 90% of the stuff I do the basic stock blade works just fine, unless your doing a fine miter for a joint then use any ATB 60 tooth blade, just check the hook angle less then 5 degrees. Could be that 15 degree blade might be grabbing the wood and moving it, but I doubt it, wouldn't do it every time. My guess is either, the glide bars are bent, or you really didn't square it up right.
To square it up, first unplug it, the put your square against the fence and blade, have the blade all the way down, move the unit back and forth along the full lenght so the square touches both full out and fully in along the entire lenght of the slide
One additional thought your saw also does both 5/8 and 1 inch arbor, just a check but do you use an adapter for that, my saw only has 5/8 so it's not an issue, but if an adapter is necessary and your not using it, might make some blade play.
