It's called "stringing". Make sure retraction is happening. I think it's turned off in the quick print profiles so don't use quick print mode. If you still get stringing you could try a lower print temperature - maybe 200C and printing at 35mm/sec for a low temperature, high quality print.

Look at the information in this first picture in this topic:
