Round 3 Notes: Print setting for part printers

Ian posted the following in connection with a question about settings for R3 part printing with a R1 or R2 TVRR.
I am reposting here to help populate the R3 guide.

• Number of perimeters - 2
• Number of solid top and bottom layers - 3 and 3
• Layer thickness - 0.3mm
• First layer thickness - 0.3mm
• Infill Density % - 0.3 (30%) should be fine. Use rectilinear fill - it's the fastest printing; the honeycomb fill doesn't support top layers as well.
• Version of Slic3r - use the latest (0.9.10b) - should be better than 0.9.8 for surface finish inside vertical holes

Assuming a 0.4mm nozzle, set the extrusion width in the 'Advanced' settings to 0.5mm for all widths. I use 0.45mm to make the pulleys a bit finer, but the walls will be a bit thicker with 0.5mm.

Tune your retraction for tidy outlines; I think 1mm at 45mm/s is a good place to start. Also tune the temperature you extrude at, and have a cooling fan on the parts as the print, for good bridging and better quality.
