For those who have used glass beds, do you just clip the glass to the existing bed?
Has anyone further insulated the sides and bottom of the bed?

1. Yes.  Plain old metal binder clips. 3 of them (can't have one at the origin).
2. Not here.

Also: Hairspray and ABS slurry using ABS pipe cement solvent instead of straight acetone.  The pipe cement solvent has some MEK in it which also solvents the hairspray (acetone does not do that very well).  Super duper stick.  We run most parts without a brim/flange.  Less trimming.

Mine has about 6 months of crud built up on it. Both abs and pla stick quite well to it.

Does your first layer look like hell with all sorts of high spots/ bad surface quality? If i dont clean mine every couple of days it kills the quality of the first layer

Warping has everything to do with heat. As Adrian has said, the heatbed is key, and the more solid the bed (as in holds the heat longer) the better. Glass works great, tile better. But you must heat them up enough (do not go by thermistor, let the glass/tile soak for longer than the thermistor says it is at temp). That has been my experience.

Oh, with glass, I use a razor blade to clean it (I dont remove my glass ever, trying to keep level for as long as possible). Its faster than acetone.

hard to beat the ABS slurry for warping...kicks hairsprays a$$

if it warps, not enough slurry smile

Hairspray is so much easier to clean.

I use glass mirror I got from Joann's. Personally, I think the mirror is cool. You can actually watch the filament come out of the nozzle....for the first layer. Aquanet.

I had also looked at the ceramic glass but the thickness tolerance was double that of the borosilicate so I passed on it.

Well.. I tried the ceramic glass.  It's not very good.  I much prefer some recovered from an old scanner.  The ceramic never heats up, it's too much of an insulator.

Did your bed any heat up faster by chance?
