No filament extruding and nozzle not clogged

Recommended Posts

Every time I change a filament (PLA) from one color to another, the material does not advance out of the nozzle. After flushing the nozzle and clearly seeing through the hole, I continue the process of "changing material" again. The filament usually does not extrude when the "wait" message is displayed. I repeat the process of "changing material" several times. Sometimes it advances and material does extrude and then I advance onto "printing" an object. Sometimes it does not and I continue to "print" anyway and try to "tune" the "flow". This usually does not work.Has anyone had a problem like this? Any suggestions as to what I should do?

Many thanks!

    • "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.
