leaking tip

leaking tip

My current issue is that when heating the tip prior to print, there is excessive runoff from the nozzle. Not a huge issue to wipe clean, but when I start to print, the first few segments do no have enough PLA material to make a line and just form sticky dots. I have combated this by creating a nice thick 3-pass skirt. Is there another way to fix this?

Blue PLA @ 180 (relatively accurate thermistor)
Mix shop nozzle w additional passive cooling
slic3r 9 (which settings would you like to know about?)
blue tape room temp

Position the head away from the print area slightly off the bed say Z = 0.1mm extrude about 5mm of plastic to prime the extruder, and let it run.
The motion to the start of the part usually wipes off the nozzle.
Nophead has a slightly better, more complex procedure described on his blog where he does an additional wipe along the edge of the bed.

Hello Polygonhell and nophead

Thank you both for the prompt and courteous replies. I am glad that my nozzle/hotend is/are not malfunctioning.
