Extrudeur renforcé pour NEVA

thingiverse

The extruder of the Neva bends consistently under the tension of the thread pull because there is not enough material, and what's more, the points of attachment are at the center instead of being at the angles. I added a arm to the new flex feeder published by Dagoma to avoid this. To print as it is, if you turn it over, you will have supports to remove on the inside and this will be complicated for leaving the arm a smooth surface against which to evolve. ATTENTION during assembly it's subtle. The extruder is screwed directly onto the motor itself connected to the tap tap sensor, so if the assembly is bad you may encounter several different problems. Assembly: 1. Start by screwing the pulley to the arm 2. Screw the metal nozzle of the white tube into the body of the extruder 3. Insert the arm with the spring 4. From there, you must, using a flathead screwdriver, press the motor and its gear against the outside face. The motor has a rounded base shape that can be precisely lodged in the plastic housing indentation. This way, you ensure that the motor axis is correct and that the thread pitches are aligned with the holes of the plastic casing. Hold the motor pressed while screwing the three screws. 5. Start by screwing from bottom right to bottom left, and finally the screw behind the arm. While doing this, make sure the detector and the two wires remain well seated in their indentation.
