Decided to make info public. In intro you asked about bandsaw cutting, in message you asked about cutting straight at 30 degree table angle.
first- do you have new blade- teeth per inch and degree? 2. What wood?
I have 3 saws. perfect cutting can be illusive. You NEED a good blade. With some woods only the right blade will cut straight.
very little experience cutiing on bandsaw at an angle, this is what TS is for. With the table slanted for angle on BS, I think you would have to set saw up with guides to retain a consistent angle. This is why we converted TS to tilting arbor instead of tilting table and if you look at BS that are built for cutting angles accurately, Giant ship building saws- the table is secure and the saw tilts.
You take a brandnew 3tpi 8 degree ( my go to normal blade) and try to cut hounduran rosewood, it will not track, no matter how good set up is. But change to 3tpi 4 degree and if feed is right you can cut straight. I do not use the 3tpi 4 anymore because 1 saw is set up with woodmaster carbide 1.2 tpi 1.25 wide. cuts trough tough woods like butter. I doubt your saw can use that size of blade- nor does it have the power. But point is you need right blade for wood you are cutting.
also- practice-hours cutting and you get feel for saw.
SAFETY!!! I hate the my fingers got nibbled stories. I spent last 2 years+ cutting maple burl knife blanks- a few- probably 30K small ones- 4 x 1.25 and 3.9 x 1.125.
to retain finger tips you need rules strict rules. in the begining I used red sharpy to make an oval around blade. No finger area. I make my own push sticks. 1"x 1/4-1/2 x12" with small v at end. crude to say the least. But cheap effective and readily available cut offs.
Your description of injury cause is something that happens easily, but longer sticks give room to stop momentum. one stick or block to keep tight to fence and one to push.
Dull blades- NO. blades are cheap- fingers are not. dull blade makes you push harder, makes for bad cuts. Most BS problems are a dull blade- most do not believe that but...
I have a book somewhere that has so much info on BS and blades, I will find and post name. incredible amount of info on blades and set up.
 
Agreed. My Dad taught wood shop and that was one of his most frequent sayings - "Is your blade sharp?" It was the same question no matter what kind of cutting tool we were using - saws, chisels, planes, knives, drill buts, router bits. The only thing he didn't ask about sharp edges was sandpaper. He'd expect us to use that stuff until all the grit was worn off.

Thank you so much, I really appreciate all you advice. My BS is brand new and I brought 2 extra blades for it, one 3tpi large blade ( think it’s 3/4, don’t think it’s 7/8) plus a small 3/8 blade, forgot tpi.
But was cutting spotted gum, Blackbutt, Jarrah and American Oak which is the softest of them all. The cuts got better as I went, but only used bs as my 10” table saw could cut all the way through at 30°. Then I planed then down to size which worked out fine, but would love a 12” ts as it’s a much better and accurate cut.
I need to spend more time practicing with different hardwood I use (mostly Aussie) and feed rates etc.
and yes, I was stupid and only used one push stick and feed from side with hand, I thought I had plenty of space away from blade, but when piece exploded, momentum just poked my middle finger in blade, wish I had a Sawstop that day. But I’m so strict with my rules for all machines, but I didn’t think the piece would explode, so now I factor that in and have push sticks and push blocks for every kind of cut.

See i prefer BS. So much less kerf. And, my opinion much safer. Blades. BS Blades do not last like TS blades. BUT cutting spendy wood, .125+- kerf vs .032+- adds up fast.
What happened to you happens to many. That and forgetting saw is off and silent but still moving is another.
 
Yep and so many times instant answer is Yep. I bought it last year...
Just ran into this at work with a planer. We basically only use this planer for cabinet work, yet when I fired it up, there were two or 3 major breaks and fine lines every eighth inch or so. Leaving me with a half hour of sanding on clear maple. Never shoulda happened. Sharp ts blade will make the difference between a "junk" saw and a great saw. Bandsaw blades... Dull can't hold a straight line in balsa wood for the small saws.
All this to say...whathesaid

Agree, but to add big saws cannot cut straight with dull blade either. Nor can mill with xx hp. Dull = heat. Heat = softening steel which = duller. End is dull cut at least or dull blade or....

Usually on big saw it just breaks
And when a 8-900 lb saw breaks a 3/4 inch blade, it hops. You do not get used to it.
My 21" 700 lbs 1.25 carbide, thicker steel absolutely scares you. Also comes out in little pieces. Bigger blades seem to pile up. Smaller blades usually come out whole. Once I had to take top wheel off. New guarded saws compared to beautiful old unguarded ones, might look modern instead of elegant but I have broken enough blades to not even want to get near a unguarded saw while running. Even though part of pile up inside is the fact that is stuck in there. Rather cut it out of saw than have it stuck in me.
