Ive printed 2 large models with absolutely fantastic results at a .1 layer height. The problem is that the bottom section that faces the build platform is just as important as the top section. The support is doing fine at supporting the sections that float above the platform but are leaving absolutely horrid scarring on bottom of the model. The default settings for a Flashforge Creator Dual are not adequate for this particular model.
Ill upload a picture to show what i mean.
