Impact of non original Spool Holders with different orientations over feeder mechanism

Recommended Posts

SHORT: Problems using orientations and locations of the filaments spools other that the original*.

 

LONG: We had a client with a feeder grinding filament on long prints (over 6hs) to the point of no extrusion after a while.

 

After checking almost everything possible: drivers, hobbed bolt, bowden tube, PCBs of printhead and motherboard, printcore, etc, we detected a significant wear over the lever of the feeders (Image wear_1 & wear_2).

 

Our hypothesys was that the filament had been feeded in the wrong orientation and it was later validated with the client (image wrong_orientation). The spools were mounted perpendicular to the original orientation of the spool holder.   So far we swaped the levers (right to left and so) and the printer is working fine again but the proper solution would be to replace the damaged part and ensure that the Filament is feeded properly from now on.

      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.
