billh 0 Posted February 2, 2012 in Bowden Tube End Cut not Square I am assembling my Ultimaker kit and the Bowden Tube End Cut is not Square. The directions stress that it must protrude exactly 8mm but it measures 8 mm on the high side and 7.45 mm on the low side. If this is truly critical then Ultimaker needs to build a jig that consists of a 6.5 mm diameter tube 100 mm + long mounted in a block with a slit square to the tube so that you can use a utility knife razor blade to achieve a square cut when the tube is forced straight in the tube.

Daid 260 Posted February 3, 2012 in Bowden Tube End Cut not Square The tube needs to make a perfect connection to the peek part. Any gap can cause melted filament to get stuck in the gap, causing blockage. So you better make sure it's square. Share this post Link to post Share on other sites
