On a totally unrelated note, what do you do when the print sticks to the print surface just fine (painters tape with glue stick on top in this case) but the print surface itself keeps pulling up off of the build plate? (ABS plastic, textured)

It seems like even if I replace the tape, either in just that spot or even everywhere, it still has a tendency to pull up a little bit. I made a particular effort to press that tape strip down with a hard roller/rounded edge to really give it good adhesion. Other parts of the tape also tend to pull up a bit over time and form little bubbles but for some reason this spot in particular seems to do it the most. It might just be that the model has the most warping stress at that point. (It's also a super wide footprint model that covers most of the build tray)

Some ideas I've had so far (in addition to replacing the tape and pressing it down hard with a rounded hard edge)

1) clean the ABS build tray in that spot with water and IPA before applying fresh painters tape
2) apply glue stick to the ABS build tray in that area, then apply fresh painters tape
2.1) do (2) but after doing (1)
3) after applying the painters tape across the whole build tray, apply a second layer at a 90 degree angle across it. (if the adhesion between 2 tape layers is better than tape to build tray, that one spot that wants to pull up will be pulling on more than one piece of tape underneath{?})
3.1) do (3) but after (1) and or (2) and or (2.1)
4) Use some other brand of wide painters tape or even the same brand but get a brand new roll. (in other words, maybe this brand of tape just sucks or it might be fine but this roll might just be really old)
5) Use another type of tape completely, possibly gaffer tape, which will bond to the build tray much more strongly and has a rough surface finish that I feel like would work well with 3D printing.
6) resort to moderately heating the build volume to ~40 to reduce warp pressure
