I do that, recently. I have 2 1/8" glass beds, which I use for ABS and PLA. I level when I switch between them, and once a week otherwise, but I remove the plates often to wash them, re-apply my glue | hairspray, and find the level to be good on re-installation.
The ABS plate goes in the freezer more often than not. For some reason, now that the weather is cooling off, my ABS-and-purple-glue prints stick like maniacs.
Cheers,
John

Got some testing done with my glass plate now, ABS sticks very well to it.
115C bed temp and 245C extruder, so far I haven't run into any issue, but I haven't tried any large models. No need for a raft so far
PLA also sticks to it, 70C bed and 205C extruder.
EDIT:
Oh, got some warping now.

What did you clamp your glassplate with? (Same question for everyone else that has a glass bed)
I found a glassplate that's normally used as a cover for big lamps they use when building houses and stuff like that (no idea what you call those lamps in English..) and it's approx. the same size as my buildplate. So it's ready for testing, just need to clamp it.
I've seen some printed clamps, but I'm afraid that those will let loose over time due to the heat of the buildplate.

For the glass bed, look at McMaster Carr for the parts. Here's the links:
http://www.mcmaster.com/#catalog/120/3646/=ubs8gj
Look at part number: 8476K74 which is 9" x 6" 3/16 Borosilicate glass and it's $19.02 per sheet.
Get two of them (one for ABS, one for PLA)
Heat-Resistant Borosilicate Glass- Color: Clear
- Maximum Temperature: 445° F, except tempered pressure-rated discs are 500° F
- Machine: Use glass-cutting tools
- Annealed, unless noted
Also known as Pyrex and Schott glass, this glass resists clouding and pitting and is highly chemical and heat resistant. With a low rate of thermal expansion, it also stays dimensionally stable during changes in temperature. Meets MIL-G-47033.
1/8" to 1/4" thick sheets have cut edges. 3/8" to 3/4" thick sheets have groundedges. Width and length tolerances are ±0.062". Thickness tolerance is±0.008" for 1/8" to 1/4" thick sheets, ±0.011" for 3/8" thick sheets, and ±0.019"for 5/8" and 3/4" thick sheets.
Now go get the following from Thingiverse: http://www.thingiverse.com/thing:278540/#files which are the clips
Then get the Z-axis stops and adjust so your heads don't slam into the glass.
For adjusting the Z-limit switch, it's easier to add a clip (http://www.thingiverse.com/thing:43783) than to replace the whole back plate.

Saw on a You Tube video something about a "green" block a guy added after installing his glass plate. Does anyone know what this is, or why he installed it? I got glass plate with my FF Creator, and tried to install it. When the bed went to leveling operation the glass was too tall and hit the left extruder nozzle.
How do you level the bed after installing the glass.
Sorry. 1 week newbie here.
Thanks,

Hi Plastic,
I was paranoid about the extruder hitting the glass when it was time to level, so I just twisted the wing nuts to lower the bed manually by about 5 cm. So, when I hit the "Level" button and the platform rose into place, it was obviously nowhere near the extruder, but no big deal, just had to approach it as if it was the first leveling out of the box.

yes, on the sides and on the front. Around 5 mm inn the build plate.
Haven' tested so much, but it sticks for now :-P

I had a hard time leveling my plate last night, it seemed like I could get both rear sides levelled, and when I moved to the center-rear it was too close to the plate. Then when adjusting both down again, it was too far from the plate on both rear sides.
Please explain to me how to...
