the other thing to try first is to slow your first layer speed down.
10mm/s is what I usually aim for, but for anything with small parts or very little surface on the plate, I will go down as slow as 5mm/s.

With abs - if it's not a heated enclosure then use a raft. Yes the bottom of the print looks awful, and if you get the settings wrong it will sometimes just not be removeable - but abs prints on rafts tend to work quite well.
Basically, How I printed everything for the first 6 months or so i had a printer.
Then I discovered everybody had lied to me about pla - and I haven't touched abs since :-)

You should NEVER need a raft with pla.

As far as adhesive of special build services - yeah, not usually an issue.
I occasionally stick a thin layer of dimafix on my printbite - seesm to rejuvenate it for 4 or 5 months or so. Well it is 3 years old now :-)
