kyma5 2 Posted August 30, 2012 in First print, problem z-movement? After weeks of hardware problems I started yesterday with the first prints. I've studied a few of threads with this issue. But I found no solution for my problem. I use: cura 12.08 normal quality print PLA 230C speed 100% Windows 7 here is my ugly 20mm cube, and then Itryied to print belt tensioner, also ugly and in the z-axis to big. some ideas?

Daid 260 Posted August 30, 2012 in First print, problem z-movement? Is the 20mm cube about 40mm in height? That could mean you have a problem with the micro-stepping. You should check the little jumpers on the Ultimaker electronics. These guys: Check them with this photo: The Z should have 2 connected and 1 open jumper.

kyma5 2 Posted August 31, 2012 in First print, problem z-movement? Hi Daid, that's the reason why the community is so glad, that you've decided to go to UM. The picture shows, that your diagnosis was right: one of the both pins was bent to the middle, so that the jumper was loose and brought a defective contact. So the cube wasn't 40mm high, but only a little bit to high. Now it prints much better and i can print the belt tensioner. Thanks a lot. Thomas Share this post Link to post Share on other sites
