Solved ABS warping! something for 3D printing newbies, put some melted ABS on your platform. Watch this video I made.

or use elmers extra strength glue.

Haven’t tried before but will give it a go 
just heat the.print surface to 80-100c then apply a thin coat enough to see the coat of glue. stuff works great.
What type platform you use for the glue? I am using perforated board, do you think is ok?
Ah, the old ABS cement approach. @danleow I bet sometimes it gets really difficult to remove a piece when completed, especially ones with smaller Z’s.
True, but I print on a perforated board so after printing I just twist the edges of the board and the model just pop off.
Nice twist-release system. You also seem to be running into something else I experienced during ABS cement trials, uneven application.
For me that resulted in cement that remained bound to the bottom of the object, once removed. What’s your approach in removing undesired cement from the bottom of objects?
In between the model and the cement I print a 4 layer raft. So the ABS cement will hold raft and the raft will hold the model. So after I finish printing I just remove the raft from the model and it really doesn’t matter where the cement sticks. I leave any excess cement on the board for my next print, as you can see from my video there are lots of white ABS cement on the board.
For me is ok if the ABS cement application is uneven on the platform because I am not printing the model on it. In fact the raft is the base for my model so the cement is sticking on the raft. Simply to say, the ABS cement is for me to hold my raft on the platform (perforated board) so it doesn’t peel off when the ABS starts to cool.
