Seems like there are a few different opinions online. I usually print with 195C extruder temp, and 94C bed temp. I though the heated bed was supposed to prevent this?
Last time I printed something the corners were warping. My bed was at 96, was that too hot?? Any suggestions?

p.s. I know my crappy makerbot white filament had something to do with it, in addition to my temp settings, but I already changed that.
Are you using an enclosure?
Those temps sound good, using an enclosure or skirt?
i also use a extruder temp of 195C and a bed temp of 95C and have a enclosed solidoodle
i print the first layer at 207C for better sticking
you could also use a raft or a skirt it creates a little layer wider than the model underneath it so even if that warps the model itself wont
but it can be a little annoying to remove it after the print
i have no problems with bigger prints but for a small one i always use raft (using kisslicer)
edit: i use ABS, have not used any PLA so far
I keep seeing people post higher temperatures but I can get my prints to stick warp free at 85bed with 184 extruder for white PLA on stock Kapton in an open case. I plan on adding a fan for bridging but I don't consider it a necessity at this point. I do however have a very tightly controlled air conditioner in my home at around 69 degrees if that makes a difference. I have experienced more problems with higher temperatures than what I show here. I haven't printed anything larger than 4" diameter but I have gone 6-7" tall.
warp free
PLA
Bingo.
I get good results once I put AquaNet hairspray down. I also have my bed set to 99 and I enclosed it with cardboard, but can only get to about 98.4. Extruder right at 192. So far having a lot of luck, but only when I added the hairspray.
Still using kapton tape too. Switching to glass before too long, but for now the original kapton bed with hairspray works like a champ.
This is with ABS

PLA practically cant warp. ive printed objects almost the size of the print bed on my SD 3 and the bottom comes off perfectly flat and smooth/reflective like glass.
ABS, however, warps like a b%^&h if you go too long or too thick in one direction.
i generally try to think about end use when i choose the plastic im going to use for a part. if its going to be close to heat, need postprocessing such as smoothing/gluing parts together, or be outside for any length of time, i go with ABS and try to design the part in a way to control warping. if its a stand alone part to be attached to the rest of the assembly with screws or epoxy, and its not going to be near heat or outside for long periods, PLA is the ticket and no design considerations need to be taken except overhangs... but ive printed some impressive near 90 degree overhangs in PLA with a good cooling fan going, so thats not really an issue either

Bingo.
Cool that PLA doesn't warp like ABS. I haven't got into ABS yet although I have some to burn. I was thinking the corners building up higher and things like that were related to warping which I was able to apparently solve in PLA with a drop in temperatures. I could be wrong I think I've been wrong 1 other time. 
I use a glass bed with AquaNet. Extruder at 185 and bed at 85. Printing ABS with no issues.
