I'm an engineer by day and, to be honest, this section I found very confusing and counter-intuitive. I went to the manual and try to follow it to align the blade to the tilt angle (pg 53 in the ICS manual). I had no problem realigning the blade again at 90 but when I went to check how it was at the 45 degree tilt, I found that the back side of the blade was out by about 0.01 (relative to the right side miter slot, it was out and away from the slot towards the left). I have aligned the blade to the miter slot before but only at 90 degrees and now I wanted to see/align it at 45 as well.
This is the first time I've had somewhat of an issue but it's probably 'user error', so I'm turning to the forums to see what your opinions are. I've been a proud owner of a SawStop ICS (industrial version) table saw for a number of years, and have had nothing but a great experience with the saw and their customer service.
