I have second thoughts about adding a glass plate on top. The base plate of the Tornado is already a piece of glass with the green (or red) build tack stuck on it. Adding another piece of glass will make it heavier. It will cause more ringing or ghosting and requires the acceleration to be turned down. We can remove the build tack and print it straight on the glass but I seen that it takes a lot work. So I tried with Kapton heat tapes on top of the build tack. It works much better. Only thing is I have to replace the torn tapes when I dug my scraper in too much. My tapes are 1 inch wide. I am thinking of getting one that is wider.
