have you tried to calculate the E-steps value? On my printer everything went from OK to fantastic in less than 2 minutes! use this guide: http://reprap.org/wiki/Triffid_Hunter's_Calibration_Guide
Even so, when printing pulleys Use the M92 command to lower the E-steps a bit further, to prevent the small blobs at the end of each tooth.
Hope this helps

Looks just like some of my prints - I can clearly see that the extra material is caused by oozing during long travel. I would guess that your nozzle moves between the areas where pro problems occur. The bits you're seeing is simply material that drips out of the nozzle and hangs there. then, just before reaching the end-point of the travel, the molten plastic is caught by the already printed mate

I haven't tried drying the filament. Although my spools are just stored in a cardboard box. I have been using other filament for a while without the problems (from grrf.de). Also a single spool of clear PLA from a danish supplier, which has been printing without issues.

I have the same issue.. I have only noticed this behavior with certain filaments. I had some issues with the red and atomic green from reprapworld.com
Is it the same as yours?

I might be completely wrong, but isn't 'E' the extruder temperature? if it is, then your thermistor might be shorted out and the printer goes into safe mode?

All my small blobs seem to form during non-printing moves, when the nozzle moves from one part of a print to another. It seems to me that the oozing (although small) is just enough to cause this type of 'blobbing'. I haven't tried to adjust the retract setting yet, but I think that will help you out on the first problem.

Now, you don't say what printer you are using, but for mine (original mendel) I have mounted a 40mm fan next to the wade extruder - pointing downward.
At the bottom of the carriage I have just put a piece of ducttape, which points the airflow (sort of) through the vents.
I have had similar problems with my j-head before I added the fan. After that I haven't had a single jam.

I have done both. Generally I tend to generate new G-code just before each print, but just out of curiosity I trid to use an older version of slic3r. i have got the exact same results with both 0.7 and 0.7.2b.
I have just seen that 0.8.2 is out! I will try that later today..
However, this tells me that the g-code should be okay, so the problem may be in pronterface or marlin/sprinter (yes, I have

Hello all,
I have a strange problem with my printer. when I try to print this The Z is not lifting enough, so the result is that my nozzle mashes around in the object. the first 5 or so layers are quite fine but from there the printer just destroys the object.
Also, when i try to print the extruder block of this The first layers (until the smaller section) prints just fine, but when the small sec
