Please use these as a baseline, I'm not into fine tunning the printer or wasting plastic with endless calibration objects, so this are the settings that I use and produces really great results from my printer, part dimensions are very accurate, but I haven't tested if the extruder volumetric calibration is really accurate.
It might produce different results with your printer, even blow up your printer or make it print a plastic robot that will try to melt your plastic roll with some kind of laser vision, so caveat emptor
