UM - Extrusion Problem

Posted in UM - Extrusion Problem

Hello,

I have an Ultimaker and when I extrude, the machine seems to offset after a certain point. It would lay down about 4 layers of a part and then start laying layers in another position that is outside of what is supposed to happen.

I have a link to a video I recorded of what happens to better explain the situation:

Thanks all

It looks like you're skipping steps on the y motor. Have you tried lubricating the rods with a little light oil? Also try turning off the power, and moving the head around by hand, and feel for any tight spots. It may also be that you have a slipping pulley - most likely one of the two short-belt pulleys for whichever axis is slipping - it looks like its the y-axis?

      "Back To The Future" using Generative Design & Investment Casting

      SteveCox3D posted a topic in Engineering,

      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.
