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:
Filament oozing at the start is normal, that's how you know it's up to temperature. The start of your g-code should have a wipe at the edge of the build plate before starting the first layer to deal with the initial oozing.
What variable was being modified in the stringing test print in the image? Personally I would just keep doing those stringing test towers and modify a different retraction variable with the z-axis each time. You could also modify temperature to see if perhaps the filament is not sufficiently fluid at 185C.
For reference, on my Ender 3 Pro I use 8mm retraction distance at 80mm/s.
