I have been reading that glass plates are really good, and the bed plates with the Makerbot Replicator+ are all not so good (I have had curling issues).
So here's the thing: thus far I've been able to cut the curling down by a) putting down a layer of gaffer tape, this seems to work well, and b) some Aqua Net which also seemed to work pretty well too at least so far (fingers crossed on latest print). I also found that simply putting a plastic bin on top of the Replicator + and using paper sheets (basically a huge pad with post-it strips on the top that I cut up) seems to do a reasonable job of keeping the temperature even -- the Z18 I use never seems to have curling problems and I suspect that temperature constancy is a huge factor.
Anyhow, I wondered what would happen if I tried to put a glass plate on top of the bed. I am assuming that I'd have to set the Z offset to like, a whole 4 mm or something crazy and that I'd probably end up with a printer crushing the extruder against a hard surface and all kinds of terrible things would ensue.
To be clear, I was thinking, get a sheet of tempered glass, clip it onto the build plate with like, binder clips or something. Replicator + build plates aren't heated, so I figured at the very least I ran the risk of having an extruder shoved forcefully into a glass plate which then proceeds to break in half.
So thoughts? Is putting a glass sheet down a really stupid idea? Like crazy stupid? It's not like I have a super duper urgent problem here, but I was curious.
