Es gibt keinen einfachen "Trick" um Blobs zu vermeiden. Eifach mit den Parametern herumzuexperimentieren bringt keinen Erfolg. Eine KI Anfrage gibt genau Bescheid, wie ich Dir tuerst erklärt habe, wie man Schritt für Schritt vorgehen muss:
Software (Slicer) Solutions
Most solutions involve adjusting settings in your 3D printing software (slicer) like Cura, PrusaSlicer, or Simplify3D.
Calibrate Extruder: Ensure your E-steps (steps per millimeter) are correctly calibrated in the printer's firmware, and adjust the Flow Rate or Extrusion Multiplier in the slicer to ensure the correct amount of material is extruded.
Adjust Retraction Settings: Experiment with Retraction Distance and Retraction Speed. Also, use features like Minimum Retraction Travel to reduce the frequency of retractions.
Enable/Tune Coasting: This feature tells the printer to stop extruding a small distance before the end of a print move, using the residual pressure in the hotend to finish the path and prevent over-extrusion at the stop point.
Manage Z-Seam Placement: In your slicer's settings (often in the "Layer" or "Shell" tab), change the Z-seam alignment to "Aligned" (to hide it in a corner) or "Randomized" (to spread the blobs out across the surface, making individual ones less noticeable).
Use Linear Advance (Firmware Feature): If your printer's board supports it, enabling Linear Advance in the firmware (like Marlin) can predict pressure changes in the hotend, providing more consistent extrusion and counteracting blobs.
Reduce Slicing Resolution: If the problem is due to processing delays, reducing the maximum resolution or increasing the minimum line segment length in your slicer's settings can help the printer's processor keep up.
Increase Cooling Fan Speed: Better cooling helps the filament solidify faster, reducing the chance of it oozing or being dragged by the nozzle.
