I recently bought a Creator Pro and am now having problems with the ABS layers sticking together. The first few layers stick but as more are added the second layer of filament warps up. I am printing with the standard slicing defaults. A few days ago everything was working fine and I was not having problems with prints. Would the room temperature have anything to do with this? Today the room was probably ~70C and the printer is located near a cooling vent in the ceiling. Every part of the print was coming undone. Yesterday I was printing (with a slightly warmer room) and there was warping but not nearly as severe as today.

Thanks!
