It happened to me in the beginning, but went away when I did a bed calibration.  Might try that if it has not been done in a while.  Im a beginner so may be better answers out there.

It could be possible your bed is too close to the nozzle and a bit of filament is rolling up on to the nozzle.  The trick is there is getting close enough to get a proper stick but not so close that it is causing your problem. I use a feeler gauge to set my bed at .15 which is perfect for most of the print option the Da Vinci is capable. If you wanted to print a .1 or lower then you would need to go down to a .05 space. However I do not believe the Da Vinci is capable of .1 or less layer heights with the stock extruder and mainboard. It claims it can do it but I doubt the layers are actually .1 when measured.

Printing since 2009 and still love it!

yep like carl said. this only happens when the bed is too close to the nozzle .
