Adjusting your Skeinforge profiles

The most important settings are:

• Dimension
  • This feature should always be activated, otherwise you get no extrusion on your Ultimaker.
  • Retracting can be enabled, if you have more patience and want a higher quality build. Make sure the retraction speed is really high. (how high is really high?)
• Speed
  • for maximum quality prints, you should set the (operating) feed rate very low, to about 50 mm/s. For several objects you can increase this speed up to about 300 mm/s without too much trade-off in quality. If your object contains a lot of curved surfaces, this requires the printed to receive a lot of G-Code very rapidly, so this creates a slow-down. It is important that this slow-down is not too big in relation to the speeds of non-curved faces or the infill.
  • Here, the most important setting is the flow rate. The outside of your object should be a nice, solid line, and the infill should have enough material too. If you increase the feed rate, also increase the flow rate proportionally. With ReplicatorG, we added a feature which which you can increase/decrease the printing speed and flow rate together, during printing. This is a nice way to discover the printing speed that works well for a certain type of object.
  • The travel feed rate can be 250 or even 300 if your printer runs smoothly enough to handle it.
  • The perimeter feed rate and perimeter flow rate settings can be lowered to make the outline of the object print at a slower speed, which usually improves print quality. Use the same number (say 0.75 or so to start) on both settings.
• Comb
  • Comb is a nice feature that makes sure the print head does not travel through holes.
