So I decided to do some maintenance on my printer and re-calibrated it to 75um on the xy resolution. And to make sure that things were working properly I thought I would try to print the sabertooth skull (from Makerbot) which failed many times previously. Basically I got a perfect print and funnily enough the lines that use to show up in my older prints (which I assume was pigment settling) wasn’t  there. The skull was printed at 75um xyz and I was really happy with the quality. Sacrificing a bit of build volume for the increased quality and speed is a good trade off. Also, this took about 2.5 hours to print.
