I have split a piece of glass with ABS before. I had eight parts lined up so as they warped, they all pulled up in the center of the bed, and they yanked out a chunk partway through the print. I ultimately modified the part slightly to allow a little warping in a non-critical area so I could continue printing full beds of parts.

Up until about 30 minutes ago I was doing fine with manual bed leveling on the Pegasus. That's when the glass broke in the middle of printing a fairly large ABS part. I guess you *can* get the part to tight down to the glass

Actually a *far* more likely culprit is getting a bit over aggressive on the pad in the center of the bed.
