in slicer support settings set support thinner than main perimeters, also find best spacing for good support and then find an angle and shape of support that works best at avoiding becoming parallel to perimeter prints walls. may need to try things like 160% angle, spaced .25mm, etc. some settings will add time to printing but save time on cleanup or wasted prints.
juts because some people claim good prints of an object in 20mins dont mean those results will work for everyone. Id rather take over 2x longer to print an item and get results Im not ashamed to sell. is my way of looking at it.
