Ultima 2 extended +, tolerances and surface finishes help


Recommended Posts

Posted · Ultima 2 extended +, tolerances and surface finishes help

I have made a coat hanger part from nylon (gcode attached),  for my engineering part drawing what would the tolerances (linear and angular) be as well as the surface finish (I'm thinking sanding grit level between 200-600). Are these parameters set by Ultima? if so how do I view or change them?

    Ultimaker published some "engineering" settings for S3 and S5.  Here is a summary of what you do to get your parts as close to tolerance as possible:


    Line width: 0.4
    Wall thickness: 1.2
    Top/Bottom thickness: 1.2
    Speeds: 35-40 (all speeds, except travel)
    Jerks: 20
    Horizontal expansion: -0.03
    walls: 3
    Inital Layer Height = 0.1
    Slicing Tolerance = Exclusive
    Combing Mode = off
    Outer before Inner Walls = Checked
