Another noob question. Sometimes when I make a cut, I'll get a ridge in the cut like the blade shifted half way through at a certain point. I know it can't be good so wanted to know what's going on and how to avoid it. I don't see it happening a lot so haven't been able to narrow it down much. I'm running a beacon star TC-14 with autofeed. I can't change the speed of the feed rate.   |

Your blade is probably starting to cup, try turning your blade around and see if that fixes it.

I get ridge like that sometimes when I shut the saw off before the cut is complete.

Agatewhisper, I have had cuts like that on a Beacon Star because the saw blade kerf was not wide enough, dull blade or the glide bars were losing rigidity.

If something causes the feed to stop momentarily (grit on the rails, worn split nuts, or whatever) you can get that result.

I've got that before when I bumped into my saw enough to move it about 1/8" from where it was sitting while cutting.
Another time when I moved the saw across the shop mid-cut. Like it flexed and the blade wasn't in the exact same place anymore.
Other than that, I can see all the other causes that have been mentioned being a legitimate cause as well.
And perhaps the rock moved a bit in the vise? I wouldn't worry about it, unless it is happening a lot.
