I am using an Ender 3 Pro v2, and I have followed multiple guides (they all say the same things) for setting up a print to prevent stringing. I’ve also switched between two filaments (Creality and Amolen) and the stringing doesn’t change at all. I have noticed that when heating up the horned, the filament just oozes out like ectoplasm even before the print starts.

I have never had this problem before, and could use some human advice.

I have upgraded/replaced the following parts in the past:

  1. Bowden Tubes
  2. Printer Nozzles
  3. Dual Gear Extruder
  4. Heater Block
  5. Heater Cartridge
  6. Thermistor Temp Sensor

    I just got finished fixing some weird oozing problems. All the settings I tweaked, the best I could get still had stringing and blobbing at the end of every layer.

    Turned out my hotend had fragments of bowden tube clogging it. I don’t know how, but assume I had the heat cranked too high at some point. There’s no real cleaning that out, and I ended up replacing the entire hotend.

    I also had a clog or damage or something causing heavy resistance in the pull-tube going from my spool to the extruder. Replaced that too and everything is printing beautifully again.
