  1. I have this recurrent problem with underextrusion (printer printing air). I have this with all types of filament of different brands/materials at the start/end/middle of a filament spool. It is simply a random generator. Sometimes the feeder starts slipping immediately, sometimes it takes a few hours, but a print of more than 10 hrs is out of question. I clean the feeder every time this happens. I adjusted tension with the screw to middle, maximum, minimum... I cleaned the bowden tube Is there anything else i can try?
  2. Thanks for the guides. (Plastic has not moved. I printed this L-shape to demonstrate the angle. I see this in all other prints but I printed this shape to demonstrate what is wrong. The curve seems to be a consequence of a cheap cell phone camera.) I will try to align axes with the first guide since visually, nothing seems wrong (bit difficult to eyeball a 88° or 92° degree angle) . I am now printing the calibration sticks. I do not have a torque screwdriver. Is this a problem?
  3. The X-axis is not perpendicular to the Y-axis on an ultimaker 3 (more than 1° off: see attached picture). Is there a way to fix this?
  4. Hello this is my first post on this forum. Prints from my ultimaker (using cura 4.6.1and makerfill PLA, different colors) result in disappointing quality. Printing in the z-axis is severely bent inwards (photo 1), straight corners are not straight (photo2), top layer is not flat (somewhat "bubbly") (photo 3)... A second problem occurs with makerfille ABS where the adhesion between the layers is very weak resulting in very fragile models. Cura has so many, many settings I don't know where to start tinkering. Any advice would be appreciated.
