    It might be heat shock. If you're starting with a really cold piece of glass and suddenly warming it unevenly with resistance wire that's embedded in the sub-plate, you could be setting up thermal stresses that the glass can't handle. You might try warming it gently with a heat gun set on low before turning it on.

    Yup, that makes sense. I'lk try prewarming from now on. And I'll look into that printbite.
