I have had good luck with hatchbox ABS, I am going to try their PETG. with the makerfarm ABS I have, I have to make sure I have it loose or I suspect it hits a bulge and stops feeding. That was when I had the Hex, not sure if it is better with the E3d, haven't printed in that color in a while. I am having a love/hate relationship with the Esun PETG, either I can't get a good first layer (thinking I need to slow it down more) or when I printed a large print I had an issue with my Hex that I had to pry it off my PEI, that I am sort of wondering if I damaged it.
