Offtopic, how are you doing abs? An enclosure is a must, with one you should be able to do successful prints so long as you have a heated bed. Give it a good long heat soak at a high bed temp (I do 105-110c on the prusa) for an hour before you even start will go a long way. If you have enclosure or bed fans, even better, you'd be surprised just how hot you can get an enclosure with just the bed, this on my v2.4 so it's a higher than the prusa
Make sure your surface is oil free, dish soap and water if your surface allows it, some of the smooth pe surfaces I've had better luck roughing them up a bit with a scotchbrite pad or brass brush. I use a Buildtak surface these days but had success with standard sheets and a brim.
I eventually built a coreXY printer with a chamber (had to build my own since the patent wasn't off for heated chambers yet, but then I'd built half a dozen printers already so no big deal) and I got pretty good prints with that, but I'd have to replace the hotend fan fairly often as it would get cooked and usually every time that would happen I'd have to do a coldpull.
I would use bluetape and gluestick to keep it down. When PETG came out, I just mothballed all that because it gave me everything I needed in ABS except maybe the rigidity, but I'd just design to compensate.
