Long filament leak when the nozzle is heating
Hello,
I'm having problems using PLA prusament for print my first prototypes.
I see the filament flowing through the nozzle during the heating process (to 205-215°c).
The filament keeps flowing through the nozzle even when the extruder motor is not running.
This results in long filaments drops (more than 5 cm) on the print table, and some filaments accumulation under the nozzle during the calibration in the begining of the printing process.
Is this normal or did I miss something?
Thanks for your help.

And to be more precise, the print is a i3 MK3S
The commonest reason for this is damp filament. As water boils off in the hotend it pressurises the filament path and something has to move.
Dry the filament and try again.
If the problem persists check your extruder temperatures.
Cheerio,

RE: Long filament leak when the nozzle is heating
A long filament leak when the nozzle is heating could be an indication of a few different issues with your 3D printer. Here are a few things you can check: Nozzle temperature: Make sure that the nozzle temperature is set correctly for the filament you are using UTV accessories. If the temperature is too low, the filament may not melt completely and could leak from the nozzle.
Nozzle blockage: Check for any blockages in the nozzle that may be preventing the filament from flowing smoothly. A clogged nozzle can cause filament to leak out the sides of the nozzle when it is heated.
Retraction settings: Make sure that your retraction settings are configured correctly. Retraction is the process of pulling filament back into the nozzle when it is not being used to print. If your retraction settings are too low, the filament may leak out of the nozzle when it is not being used.
Hot end assembly: Check that the hot end assembly is properly assembled and tightened. A loose or incorrectly assembled hot end can cause filament leaks.
Filament quality: Poor quality filament can sometimes cause issues with leaking. Make sure you are using high-quality filament that is compatible with your printer.
By checking these possible causes and addressing any issues, you may be able to solve the problem of a long filament leak when the nozzle is heating.
