that's funny~~

just keep everything tight and unmovable.

also, we use anti-roll guide to keep the sections flat
so, sometimes there is a bit OCT attached to the blade/glass/anti-roll guide or surrounding the tissue.
clean it.

have you tried to cut at a higher temperature? the tissue could be too hard ! this always happen if you are using the frozen microtome, but applies to cryostat as well.

You've gotten great advice so far, but if it doesn't help--our problem was
that the specimen head was loose--even when it was locked, it would move
very slightly.  This has to be fixed by servicing it, unfortunately.  It was
caused by our MD/PhD student trying to adjust the specimen head when it was
locked, hence loosening the screws.  It happened even though I told the guy
to quit doing it, which drove me mad.
How some people get this far is beyond me.
