Well, considering that the board was bought at Home Depot and required the hold-down
clamp to flatten it against the saw's table, it is definitely scrap.


So is it the saw or the board that is the problem? Could the board be
moving once the blade stops? Have you tried a different board?

I wonder of the force of the rotating blade is causing some stress that
causes it to move during the cut.

I'm going to stop and pick up a perfectly flat 1x12 later today. There's a lumber yard near
my work where I can get good wood.

I don't think the board is moving because it is clamped to the table to keep it flat. It's the
clamped side that's showing the groove. I'll test a few more things and removing the
possibility of the board causing the problem is my next step.





A piece of MDF or plywood should work if you have a scrap laying around.

It be the saw.

Here is the 1/2" MDF:

I tried 2 different blades and I tried both with and without the hold
down clamp. The groove might be ever so slightly shallower without the
hold down clamp, but it's still there.

I also tried to eliminate user error by keeping some left-ward pressure
on the head unit throughout the entire cut. Theoretically, this should
have pulled the front of the blade away from the board, eliminating the
groove. As you can see, it did not.

The call goes into Amazon tomorrow.

Dammit!



Well that sucks. I would not give this particular saw a third chance...
Did you by any chance check the serial number or determine when it was
built? Wondering if this was one of the early ones that had issues.

I just spoke to Amazon. I have to give them props.

As in the past, it took less than a minute on hold to speak to a live person. After I explained
the situation and let her know that I wanted a replacement, she put me on hold for a few
minutes and when she came back she told that the return authorization will be sent via
email, the replacement saw should arrive on Friday and UPS will pick up the broken one
tomorrow.

It's supposed to be a busy weekend for me, but I'll set the saw up as soon as possible and
do some more testing. Stay tuned!

I bought my Unisaur from Amazon and also found them to be very
responsive.
