That's good to hear, during my builds almost all of my print issues were coming from supports failing or printer components beginning to wear out and I was pretty new to 3D printing so I didn't know what to watch out for so it led to extra unnecessary finishing work.
Glad to see that you got it fixed and are just getting ready for your next step! I personally just use PLA myself and I haven't had it be an issue yet. Although I have ordered in some PETG for testing because I've been told it is a good material to work with in the finishing process so I wanted to try it out.
I've thought about using ABS, but I don't really need weather resistance or components that are that tough. I also use an Ender 3 and a CR10 S5 so I don't want to take the time to build a box to vent the fumes out for safety if I don't really need the positive aspects of the material. Like you said an unnecessary hurdle.
