Stringing/Oozing Problem
(lemmy.ml)
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:
- Bowden Tubes
- Printer Nozzles
- Dual Gear Extruder
- Heater Block
- Heater Cartridge
- Thermistor Temp Sensor
My Tweaked Settings:
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.
