I have started covering my heated bed with a dry paper towel while it's heating to insulate it and help it heat evenly. This, in addition to an acetone slurry squeeze from a paper towel over my heatbed at 105C really helps ABS plastic stick. 250C seems to be the right number for the nozzle temp.

I'm very curious if editing the code like you did helped at all.
If I had one guess to explain the error in your image (one I have seen on my printbed several times) it would be this: you broke some (or all like me?) of the blades off of the extruder fan and your extruder has a metal gear?
So here's the idea, if the filament conducts heat up from the extruder barrel and to the extruder-gear area it will make it easier for the gear to "cut" or "strip" the filament, rather than pushing the filament forward.
This issue is compounded by
Once the filament starts to strip, the torn peices of plastic fill the extruder's gearteeth, which make further stripping more likely.
