Thanks for the reply's. We now added the belt tensioners but it doesn't seem to matter much. As you guys can see in the picture the round shape still isn't perfectly round. I also uploaded a picture of our slider blocks, since we made a adjustment there by adding some spacers for the axes. otherwise they were to loose, could that be the problem?
Hi all, For a school project we had to assemble a Ultimaker. But now that the printer is assembled we can't get him to print round circle's. We are trying to fix it for quite some time now and tried multiple solutions. -Belt tention -Different settings in Cura -Axis alignment and i think we tried some more things but i can't even remember. We are testing the UM with this file: http://www.thingiverse.com/thing:170922/ and use the 10mm version. As you can see in the pictures the squares are good, but the circles arent round enough. We hope you guys can help us! Dear Regards
