About this generator
Strings between the towers mean the nozzle oozes during travel. Adjust retraction distance and speed until they disappear.
How to use
- Print the test.
- Check for strings between the towers.
- Change one retraction setting at a time and print again.
Printing tips
- Wet filament strings a lot: dry it first.
- Lower temperature also reduces stringing.
