Hi, I'm very new to 3d printing and I got myself an Ultimaker 2+, printed a couple of things with the standard PLA fillement you get with the Ultimaker and used some colorFabb XT Sky Blue and I got PERFECT prints all the time. Got one failed print but that was my fault only. Then I tried to print a dragon head, quite complex and large. The problem didn't occure with the size or the complexity. It was the problem that the first layer didn't stick right. I printed Frostmourne sword from world of warcraft a few days ago and one of the freestanding SMALL horns didn't work as intended, i thought nothing of it and just continued printing awesome prints. But ever since the first attempt at the dragon head I can't get the first layer to stick properly. I've tried everything I can (i think), lowering the temperature, raising it both with the bed and the nozzle. Tried different materials, tried raising the extrusion speed, lowering it. Tried to use the fans in MANY different setting with the first layer (and without fans). Tried glue on the print bed, the blue masking tape. And I re calibrated the print bed a few times, trying to low, to far up. Used another slicer. I Can't seem to get it to stick. Please help! Sorry for the bad spelling
