The nozzle leaves spider-web-like strings between prints or portions of the same print. The printer stops printing to perform a travel move but the nozzle still leaks and slightly strings from one print to the other.
The retraction settings must be set properly. Lowering the print temperature slightly in some cases may help, this should not be the first option. Verify that the retraction settings are properly set before adjusting print temperature. Retraction Distance: 0.00mm
