I've been calibrating and dialing in my new M2 for the last week or so when I have time to work with it. I'm currently getting some really nice prints - loving Creator. Bridging is the next area I'd like to focus on. I've been using both the 5 mm Calibration Steps http://www.thingiverse.com/thing:24238 and the Ultimate Calibration Test http://www.thingiverse.com/thing:9804. And to be fair they both look quite good.
With the 5 and 10 mm overhang sections of the 5 mm Steps I get small loops that drop down with the bridged infill.
With the Ultimate Test I get some sagging starting at around 15 mm.
Again, I do think they both look quite good - but I'd like suggestions on what settings I might try adjusting to really kick it up to the next level.
