Cubes to get rid off stringing/oozing.
Set up travel speed (for non-printed lines) pretty much high. In my case: 150 mm/s.
Optional: Set retraction settings all off to see how much stringing you will get.
Turn on retraction settings in your slicer.
- Retraction distance: 1 mm
- Retraction speed: 50 mm/s
Still some stringing?
- Increase retraction distance by 1 mm per print and look and your results.
- I recommend maximum distances up to 5 mm/s for direct driven extruders.
- Keep the best setting for your retraction length
- Start off with a retraction speed of 10 or 20 mm/s and increase by 10 mm/s
- I recommend maximum retraction speeds of 70 mm/s
- You should now see no more stringing. If you stell get stringing, take a look at the following troubleshootings:
You extrude too much material so that your nozzle runs through printed areas and carries the plastic towards the edges. Try reducing the flow.
b) Mechanical problem with Z-Axis:
Your printer does not print the exact height you want it to print and therefore runs through printed layers (see Overextrusion). Take a look at your belt tension or trapezoidal spindle.
c) Printing temperature too high:
Retraction still can't handle very fluid materials, so try to reduce your printing temperature and therefore get a little bit more viscosity to the material.
d) Try to get help in the comments ;-)
Let me know whether you printed the part and it helped you to get rid of stringing/oozing in the comments!
