Weedo X40 avoid misprints

Misprints are not only expensive, they also often cause environmental damage, since CO² is generated unnecessarily and the printed object is not recycled. It is therefore always worthwhile not to produce any misprints. On this page I would like to show you how you can avoid misprints or how you can correct the faults.


Here are important tips to avoid or reduce misprints:

  1. Calibrate your printer
    A printer calibration can not only correct the dimensions, but also avoid over- or under-extrusion. An extremely incorrect PDI can also lead to temperature fluctuations and corresponding errors.

  2. Setup your printer
    Another very important point is to set the printer correctly. Perform the bedlevling, set the z-height correctly. The height of the right-hand nozzle must then be adjusted to that of the left-hand one. Now correct the XY nozzle offset. Caution: If you transport the printer to another location, change the nozzle, correct the belt tension, etc., you will have to carry out the setup again!

  3. Use slicer print profiles to avoid unnecessary mistakes
    With an FDM printer it is not enough to set the right temperature and desired speed. In Cura and other slicers there are hundreds of different parameters, e.g. for setting the support structure, bridges, etc., and some of these are also dependent on layer heights and nozzle diameters. It is therefore extremely useful to determine the correct print parameters and save them in print profiles. This is the only way to achieve good results with just a few clicks and thus fewer misprints.
    The use of the X40 community print profiles reduces misprints, since all important parameters are matched to the material.

  4. If possible, use filaments with a small diameter tolerance and good quality
    Almost all beginners look at the price of the filament and buy cheap ones from Amazon. Almost everyone goes through this learning phase. Those who have experience know that it is not worth buying cheap, inferior material, as this results in significantly more misprints and often more costs overall than if you buy more expensive branded material. Most good filament manufacturers are not found on Amazon, but in specialist shops or directly from the manufacturer. The diameter tolerance has an influence on the material flow and thus also on the print quality. It is recommended to use filaments with a diameter tolerance of max. +/-0.03mm, so that you don't have to correct the material flow to get the perfect result.

  5. Use suitable print bed surfaces and, if necessary, adhesion promoters
    Choose a suitable print bed according to the filament. Some materials also require an adhesion promoter so that the print adheres better or can be removed. When changing the print bed, think about bed leveling and adjusting the Z height.

  6. Dry the filament before use and store the filament properly
    Most plastics absorb water when stored openly. Some even change so much when stored for a long time that they become unusable. The moistest filament cannot be processed well and can cause misprints. If necessary, dry the filament beforehand.

  7. Check the slicer preview result
    Use the Cura preview to check whether the settings for brim/raft, support, etc. are correct or sufficient.

  8. Check nozzle size and start extruder
    If you use different nozzle diameters, you should check whether the nozzle diameter set in the slicer matches the hardware. Cura also likes to start with the wrong extruder. It should therefore also be checked whether the start extruder and the assigned filament are correct. With the X40 PRO configuration, the start extruder and the nozzle diameter specified in the slicer are shown on the display.

  9. Check if material is enough
    Especially with long prints, you should check whether the amount of filament is sufficient. If it gets tight or even a filament change is to be expected, then it should be checked whether the filament sensor is active and whether it works.

  10. Learn from the misprints
    Never is perfect and you can't rule out misprints 100%, but you can drastically reduce the error rate by learning from the mistakes.
    There was a misprint because the filament got knotted. Think about how to avoid knotting in the future. The solution is a filament clip that you can download and print at Thingisere. If you use the clip consistently and correctly, then you have ruled out the error with a high degree of probability.

  11. Don't get lost in the chaos
    Beginners in particular tend to want too much at first, even though they don't yet understand the system. When something goes wrong, you get stuck and frustrated. The Weedo X40 Idex printer in particular is a complex system that only works properly if many parameters are set correctly. Therefore, you should first print and learn simple things for a while. Immediately converting the printer because you want the maximum possible is probably the worst choice for a beginner.
    Please note that a 3D printer is a very cheaply manufactured machine. An incorrectly adjusted, maintained or programmed machine can quickly lead to a defect. So you not only have to learn how to operate the machine correctly, but also how to adjust, maintain and, if necessary, repair it.
    Anyone who is not ready for this has chosen the wrong hobby.



How can I fix the misprint

There are plenty of sites that deal with troubleshooting. Most of the time it is due to incorrect parameters or missing or incomplete printing profiles.
