What the hell is going on here?
I know humidity can effect the material pre-melt, does it also effect adhession to the build plate?


If you are having issues with ABS sticking, use Blue tape with a glue stick (like a kids glue stick, or Bostik Blue stick... anything like that) smeared over the top of it at 110 degrees. Make sure you smear the glue stick immediately before the print, and not at the start of preheat or the glue will dry by then. Make sure if you are using blue tape, you put it over the glass, kapton or whatever when the bed is cold. Press hard, make sure that tape is stuck to the bed.

*Lay your blue tape down on your hot bed with a very small gap in-between each piece. Do not overlap the tape or it will rise during print.

*When you smear the glue stuck - make sure you also go over the cracks in between the pieces of blue tape - this will stop it lifting off the bed also. This is pretty important this part.

*Dry glue is much easier to scrape (with your fingernail even) off a glass bed than something like ABS acetone slurry. Pretty soon you will be buying glue sticks by the dozen.

By the time the second or third layer is being printed, the glue will start to cure and the base layer will be stuck well and truly to the bed, it will not lift off.
