It is an alignment problem. Also chipping at the scoring line indicates a 
too high pressure of the scoring wheel onto the glass (there is a set screw 
to loosen the pressure next to the scoring wheel, you have to remove the 
head to adjust). I have an instruction sheet with drawings to align the 
knife maker.
I can send you a copy.
If you still have a problem after alignment, I can recondition and align, 
add a new scoring wheel/pin for a modest charge. Please contact me off line.

Basically I'm getting knives, even squares, that are not straight on the 
edge. So, I think the scorer isn't lined up right. But, when I get squares 
to break, the pins seem to be too far to the edge because there's sometimes 
a lot of cracking and chipping that's going on too...
The head histologist in the lab says she fixed it, but if anyone could help 
with general tips and/or guidlines for the future, it would be much
