Hi,I had the same problem, small parts was more like a swirled pile of plast, than what i tried to print. But the fix for me was definately adding cooling fans to my hero.I bought 3x 120mm pc fans, and a 12v power supply, as to not put any strain on the controller. Then wired the fans to the powersupply and put them around my hero one on each side. I then engage the fans as soon as the first couple of layers has bonded to the build surface.Here is a photo of my setup:I use a start temperature of 220 for the first layer, and then 190 for the rest. Ive had some pretty decent results like this.Also i use a normal glue stick for very small prints, so the fillament sticks better to the surface.Hope you get more luck with your hero!
