Printing ABS, more adhesion is a good thing to prevent warping.
As you gain experience, you’ll be able to judge optimal initial nozzle height by looking at the bottom surface. The smoothness/roughness of the surface is as also a telltale sign of adhesion.
I like a pretty smooth bottom, but watch out for widening of the first layer. I also like a multi perimeter skirt, which I usually have to scrape off the PEI bed.
Last tip, pick a filament brand and stick with it. Dial in the extrusion temps and bed temp to get the most consistent results. I like eSUN ABS primarily because of price and I can get a 5kg roll. Print quality is good for the prototyping and my typical projects. My settings are initial extrusion and bed temps of 245 and 110 with no cooling from the print fan. At layer 10 (~3mm), drop the temps to 240 - 243 and 90 - 100 (still good adhesion, but allows bottom of ABS to cool rigid) with little to no cooling. For taller prints keep extrusion temps high 243-245 with no cooling to help adhesion of layered and prevent “splitting” as the project layers cool.
Hope that helps. Happy printing.
