Filament dripping out of nozzle

as the nozzle melts the filament a liquid a hole and gravity will work together to allow mior amounts of filament to ooze and this is fine sometimes I get oozes as long as an inch to 2 inches depending on hogh the nozzle is and how long it has been sitting there while hot when starting a print the nozzle is at the home position and it normally rises about 5 mm and does a small extrusion of filament I simply use a tweezers and grab that excess before it moves from the home position as for it causing your first layers not to stick I believe there are manyother factors causing that but with out more information it is hard to tell. I say this not be difficult but to let you know other things affect it more such as the z height levelness of the axis and of the bed give us some additional info and we can help get you going quickly
Material ??
temps ??
bed ??

 

Hey Jimmy, well as everyone else has said some dripping, or ozzing is ok. Even if it is a few inches as their is nothingstopping the filament from falling out of a hole, so to speak, when it is in a molten state.

 

retracting should only be done while a print is running if it is oozing too much simply adjust the temp downward by about 10C and then raise it back up when you print usually the printer will set that anyway.

I am making an assumption here oozing is describing the leaking or dripping of filament when the printer is in between print jobs and everything is just sitting there.

If this is the case then just lower the temp as I said above if you are not talking about oozing then let us know when and where you are seeing this happen

 

Oozing is actually one of the reasons that you print a skirt. It gets the nozzle nice and primed with good material, Ready to print. You really don't want to be printing with that initial filament in your nozzle.
Other slicers will put an anchor down (a little blob at home with a line leading up to the print) or a big wide line along the front of the printer.

 

Yeah, I get that too. The taper on the tip of the hot end is awfully shallow.
I usually just watch and yank the little blob out with tweezers while the skirt is printing.
It's always best to watch at least your first layer anyways.

 

the best trick is to add a bit of code to beginning of each print (donein the slic3r software) to raise the z 5mm then do the extrude then you can easily grab it before i start printing anything
