Welcome Dennis. This is a great site.
I had the same problem with my DW788 but found a cure.
Place a blade in the saw and tighten. Using a steel ruler, place it on edge and place the end against the side of the blade with it in its lowest position. Raise the blade to its highest position and see if the ruler is still as close to the blade as before.
If not you will need to adjust the set screws to align the blade with the end of the ruler. This will take several tries, but well worth it when adjusted properly. Makes a large difference when cutting fine details.
Hope this helps.
