Underextrusion at top left corner of bed

Recommended Posts

My guess would be higher friction in the bowden due to the more extreme curve on that position. It's basically why I made this;

though this should probably not be necessary with a good feeder....

 

Nevertheless, using a PTFE Bowden tube 8-12" longer than OEM will reduce friction considerably.

Here's the stuff you want: http://www.amazon.com/gp/product/B00KJDE67G Also comes in 10" length.

Some measured numbers for this reduced friction would be interesting. Are you referring to total friction or friction per length?

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
