In a recent and exciting development in the reprap community, the members have begun a forum topic page on how to best calibrate your temperature settings for maximum efficiency and print resolution. The material topic at discussion here is ABS plastics. Avidgoodenough, a reprapper going on 3 years and active on the forums notes that Pronterface SFACT has only a PLA setting and suggests the community develop a documented profile for ABS as well. Brnrd, another active reprapper recommends the use of lower temperatures on the first layer of print (if printing with a raft), so that the part would be easier to remove. Brnrd relates that the higher temperatures are needed if printing without a raft directly onto a bed to allow for better adhesion.
