I have an LT28 and I've been thru the alignment procedures in the manual.... now what? The last log i had on the mill was 1/4" away from the top of the back stops when i turned it over. Plus the cant ended up 5/8" wider at the far end on an 8'6" log. Any ideas?

First thing I would do is call Woodmizer. They have amazingly helpful customer service people.

If it all of a sudden happened,  you could have had a thick chunk of bark or other junk under the cant.

Is the cant square?  Maybe the back supports need adjusting?

I had that same problem.  For me it turned out to be a dull blade.  As soon as I put a new blade on, my mill cut straight again.  It was the FF gang who helped me on that one.
There is nothing like the natural beauty of wood.

Anytime I notice my mill doing something funky, the first thing I do is change the blade out with one that I know is sharp and has plenty of set. Fixes it 98% of the time.

Even though my log stops are plumb n squared I use a torpedo level and always check face before second cut.

  that way I know I have a perfect 90 degree.

Partially dimond shaped cants arent as big of an issue if you're making all lumber. Posts and beams are a different story.

I always turn 180 degrees which helps enormously had a lot of parallelograms when turning 90/
also less edging..

I do the same as pete takes a bit longer to saw a log, but is a time saver in the end.

I think 180 flipping is faster, because you end up with less flitches this way...

Glad this thread came along. After feeding the animals this morning Iwent to the mill, put on a new blade and started the first log, the cant wasnt square, it was a 1/4" out. I got my framing square out and my stops were leaning out an 1/8". So even tho I my first two openings are 180 from each other makes them parralel , I flip 90 up to my back stops cut that face and thats when things go wrong. took about 20 minutes to adjust all 3 stops and good to go

"Won't" cut square and "didn't" cut square are two different situations.  Won't is an adjustment that is out of whack.  Didn't can be caused by many different things such as stray piece of bark or maybe just a stubborn cant that did not snug up to the side supports properly.

Whether you turn 90° or 180°, being observant and developing a consistent sawing technique is a must.

From my arm chair....
-the sawyer should be the first person to hold a square to the wood.
-mill not cutting square is like car not driving straight.
-shouldn't be airing this in front of swing millers. ::) ::) ::)

 Not to hard to keep lumber square on a bandsaw if the stops  are square and you keep the cant tight against them.  Sigdi, have you ever cut 5 2x4's in one cut.   Steve

Steve, I've tried makin 5 6x1 into 4x1 before, but the way the mill is designed - normal cutting negates the need for 'edgeing' boards, but having said this doesnt mean it can't be done ;)

I'm not tyring to knock swing mills but don't knock bandsaw either, both do some things better.  I have a friend who has a swing mill that brings me some logs to cut and I give him some big ones to cut.  The best would be to have both.   Steve

One time I had a sawyer that couldn't get the WM to saw square.  He finally came to me and said he adjusted this and adjusted that and just couldn't get all the corners right.
I took the square and checked his cant.  By using the square you could see that you had 2 adjacent right angles and 2 angles that were greater than 90 degrees making it about 370 degrees total.
Euclid said that was impossible  for 2 adjacent angles in a quadrilateral to be right angles and the other 2 to add up to more than 180 degrees.
I told the sawyer to get a new square and check the square to make sure it was square before adjusting the mill.
Things went well after that.

I have a 12" aluminum square that rides under my operator's seat.  I occasionally check a questionable cant, especially large ones.  It is neat to lay it on a square cant when the customer is watching.   ;D

Never say a word.  Just check the cant, put the square away, and keep on sawing.   :)
