Underextrusion after retraction.

Recommended Posts

Hey there!

I've had this UM2 since early 2015, and it's worked great. Recently, though, I haven't used it often, and I decided to put it back in use today. I did a test print (Leatherman Wave Holster) and the print went really great... up until its first retraction.

I had underextrusion issues.

For every layer without a retraction, the print went perfectly fine. But as soon as it started the belt clip (and retractions started), I got underextrusion. Then, once the belt clip section had ended, the print quality went back to normal. I've included photos of this issue below.

The print cracked when I tested it's strength.

Here's a screenshot of my settings. I used ABS, with a 0.4mm nozzle.

I'm not entirely sure about this, but could the Teflon insulator be the problem? I haven't replaced it yet. Thanks! I hope I can get this problem resolved.

    • "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.
