Problem with retraction

Recommended Posts

Hello everybody my name is Natan and I'm having troubles with my UM2.

Since I bought it I can't have clean prints without the stringin.

I try printing in low temperatures and high speeds but I can't solve it.

Every time that I put more than 1 model it stringing everywhere.

I can see that the material is been extruded when the hotend is traveling without printing.

I show you a pic.

Please if anyone has the same problem and you solve it or any help will be welcome!!

Thanks!!

White PLA is especially bad at stringing. Can you maybe try a different material?

Printing cooler is great but printing slower helps also (and travel speed fast). These strings look very thin and probably are easy to remove.

I guess you already did this, but just to make sure: could you verify in Cura that the checkbox "Enable retraction" is checked indeed? Then verify in Cura, in Layer view, that extraction is active (=small dark blue vertikal lines). It could have been disabled accidentally, or on purpose to try something, but that you have forgotten to enable it again?

    • "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.
