Extrusion when moving from piece to piece.

Recommended Posts

My Ultimaker2 sometimes does that strange thing, when it starts to extrude the filament when the printing head is in the motion from one element of the print to another. This string then sticks to the already printed side of the print, often looking like a tiny loop or a bundle. This is not the stringing problem, though, as the unwanted piece of plastic is flows out at a constant diameter. These guys are not especially hard to clean off (often it's enough to just nudge them with nail), but I still don't know why do they happen. It is as if gcode glitches out and there is mismatch of timing of extruding commands and positioning commands (I watched my print in process, they seem to start flowing right after head starts to move to a new destination). They also often happen around one specific area of the print.

The prints, otherwise, print out very nicely and I have no problem with them.

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
