not a problem...more than happy to help.
ABS is tricky...you have to print it incredibly hot and you really need an enclosure to get the temps just right. plus it strings easily (even with super fast retraction settings) and can cause a real mess for post-print clean up. this is why i abandoned ABS for later only if i absolutely had to.
my printer head runs hot so my head temp reads on the low side when it is more like 20-30 degs hotter than it shows.
i use a bed adhesive. the adhesive is the usual glue stick kind...just apply and spread it evenly across the surface.
the key for me to get good bed adhesion (in addition to the glue) is to run the first layer with a bed temp of 70deg (with reduced print speed to 50% and print layer width to 150% and a brim three lines wide and one layer thick)...then drop the temp to 60 for layer two and then 50 for layer three and beyond.
all layers printed with a static head temp of 190 for PLA and 195 for PETG. adjust these temps for your specific printer quirks and material specs.
I am also using an enclosure that creates a stable ambient temp of 32-33deg (with the aforementioned bed/head temps)...this gives a temperature gradient of only 17-18 deg from the bed to the surrounding air. this does wonders for warping and curling.
Here are the screen captures for the settings i use in Simplify3D plus a pic of the supports and orientation for the split model.
