Brand new to 3D printing and have an Ultimaker Original + using PLA (2.85mm). The nozzle/extruder temperature is 200C and the bed/plate is 60C.
I installed the Cura software on my Windows 10 box. I then head on over to tinkercad.com to make a model of a comb. I then exported my .STL file and loaded it up in Cura. I hit the print button. I waited a bit, but noticed that my print was getting lumps in it. Not crazy drastic lumps, but because the object was small, gaps (between the comb teeth) were being filled... not all of them, just some.
I tried adjusting the flow rate from 100% to 90% and it seemed a little better (not perfect, still filling gaps), but when I dropped it lower, it got worse.
I also tried to lower the print speed from the default of 60mm/s to 50mm/s - no change. (travel speed at 120mm/s)
I tried to adjust the bed height multiple times, trying to make sure that it was 100% flat at 180 degrees.
What is wrong here? Is the printer over extruding? Is the temperature too high? Is the flow rate wrong? Am I missing something else?
Check out my prints:
I also tried printing something else:
Any help would be really appreciated.
Okay, so thanks to macs answer, I took another look at the nozzle and noticed a massive leak - I actually dismissed this earlier as "glue" - OMG.
Anyways, here is the picture of the leakage:
It's very bad. It leaks down and runs over the nozzle. The nozzle also leaks... Is that normal? All I did was turn the printer on, heat up the nozzle to 200C and it started to leak. I suspect that it should not do this... I'm not ready to change the nozzle just yet - I've no idea which one to buy or even where to buy it from (I'm in the UK), so I'd like to get this one working (if possible).
On another note, I have checked the filament settings - All good. Heat settings all good too:
