  1. Hello,

    I am currently using the Cura default speed and temp for Ultimaker PLA at .15 layer height (70mm/s at 200C) and am getting incredible underextrusion on the infill. The outer layers all look as hoped. Can anyone offer any advice in regard to a better ratio? I am just surprised the default produced such a poor result.[media-thumb=30238]

    Thanks


  2. Literally just posted about the same thing. I knew it was the active leveling, but it is loud in comparison to how much the axis actually moves (probably a fraction of a fraction of a mm). I wish I could set a threshold for active leveling. i.e. the active leveling only engages when the z-distance between two points is greater than x distance.


  3. Hello all,

    I have recently purchased an Ultimaker 3 and have been playing around with it for some time. All of my prints have been nearly perfect so far, so no concerns on that end. However, the z-axis does make a constant "creaking" noise while layering close to the center of the bed. I am fairly confident that this comes from the auto-bed leveling microadjusting when the nozzle is printing back and forth close to the center.

    It doesn't affect print quality at all and it isn't louder than the other axes. However, I can't help but wonder if it is putting unneeded strain on the z-axis stepper motor. Does anyone have any thoughts or experience with this?

    Thanks.
