I'm having a problem with my BT3100.
I'm trying to build a simple box, a speaker cabinet actually, to replace one my youngest managed to break.
I tried cutting the sides to length with a 45 degree angle on the cuts, figured I would then glue them and use my nail gun to put in a couple pins to hold everything in place while the glue dried, plus some clamps.
No so simple, as it turns out.
You might wonder why, after several years of using this saw, I have never encountered this before. Well, I primarily build mission furniture which doesn't need angled cuts. At least not the pieces I've built.
My problem is that when the blade is tilted at 45 degrees it cuts crooked - but not when at 90 degrees (straight up). The attached picture shows the situation.
I hope the above is clear when combined with the pictures.
I spent the morning going through the alignment processes for the sliding miter table (SMT) and fence. Each was off a bit, I corrected them as best I could (my digital caliper says I'm within a couple thousandths of an inch) and hoped my next test cuts would be perfect.
Nope, same problem. Perhaps a little bit better but not much.
I'd be less surprised if the cut was crooked when the blade was straight up AND when angled at 45 degrees. But straight up cuts work fine. Angled ones display this problem.
My setup:
I do not understand what's wrong, what problem could produce perfect cuts when the blade is straight up but crooked ones when the blade is angled 45 degrees?
I'd welcome any wisdom this group might have to offer.
Thanks.

My problem is that when the blade is tilted at 45 degrees it cuts crooked - but not when at 90 degrees (straight up). The attached picture shows the situation.
- Top left: shows a straight cut (blade at 90 degrees to the table top). The vertical edge of a plastic draftsman's triangle is aligned with the edge of the cut. The red oval outlines the area affected and the yellow line shows the cut. As you can see, the edge of the triangle is perfectly aligned with the edge of the cut, just as it ought to be.
- Bottom left: same shot as top left but with the red oval and yellow line removed for clarity.
- Top right: This also shows the long side of a draftsman's triangle placed along the edge of the cut. In this photo the yellow line follows the edge of the cut and the blue line the edge of the triangle.
- Bottom right: same shot as top right but with the red oval, blue line, and yellow line removed for clarity. The edge of the cut is not parallel with the edge of the triangle, the cut actually angles away from the top edge of the plastic triangle.

My setup:
- Using SMT to push the wood through the blade
- No clamps being used to hold the wood in place that might warp it or lift it off the table
- Not running the wood against the fence, it isn't even touching the wood
I do not understand what's wrong, what problem could produce perfect cuts when the blade is straight up but crooked ones when the blade is angled 45 degrees?
