Glass Bed, What and Where would you get one?

[soofle616]

Well, printed the spacer, installed the glass bed, and promptly had a horribly failed print. nothing stuck at all (i tried it with bare glass, cleaned with rubbing alcohol, printing abs). So nbd I didn't really expect it to work without anything on the surface. Busted out my glue stick and gave it a good thorough coating, let it dry, tried again. Still nothing. Cleaned off the glue stick and covered the glass with kapton tape (since the real reason I got the glass was to get away from my warped bed I don't mind if I still have to use the tape), still no dice. The purge line, second shell, and infill on the first layer all stuck but the first shell didn't so I ended up with a gap between the shell of the part and the infill. Not to mention the fill itself looked like it was separating from line to line. So my assumption here is that the glass is taking longer to heat than the aluminum bed which is resulting in my bed temp being too low. Does that make sense? If that's the case, I'm seriously considering removing the aluminum entirely and running the glass directly on top of the heater, probably secured with some sort of perimeter restraints though I would likely make them out of metal so they don't soften with heat. Any reason i should NOT do this?

Edit: having now removed the glass plate I seem to be getting the same gap between my infill and shells. Looking at the picture it's pretty clear that things are not sticking properly but why? bed temp is 110, kapton was cleaned with rubbing alcohol prior to the print being started, print temp is 230. As far as I can tell, nothing has changed other than there was a piece of glass on it and now there isn't.

2nd edit: Problem fixed. Though my bed was level apparently it was too low (thin paper from now on, no more business cards). Haven't gone back to the glass bed yet but things are printing properly on the aluminum one again so at least the "damage" has been undone until I have time to play with the glass some more.
