PLA gets warm and sticky in the cold end but if you have a strong extruder and a tight tensioner you can power through this. Alternatively you can try to clean out your heatbreak/hotend and put a bit of olive oil in and bring it up to around 240 C for a few minutes, this should reduce the friction (i do this cooling fan off so the cold end heats as well)

If the filament is pulled too far up the sticks retract the molten filament fixed to the walls of Heatbrak. So it is there always soft, compresses itself when it is pushed to the nozzle and jammed.

I assume you are using an all-metal-Hotend?
It is a long known problem that PLA into this for so-called jam.
What do you have recognized melts the PLA already in heat break and sticking to the walls.
There are only two solutions:

You have the heat meeting between heatbrak and heatsink improve with a thermal grease and for optimal ventilation and heat dissipation ensure this. Given the retract in Hotend should not be greater than 0.8mm. This works but not always, and it is also dependent on the respective filament.

The second way that we used is the use of specially coated Heat breaks and nozzles. Thus, the friction on the surfaces will be better than with teflon ind the PLA can not stick melted. I do not know if there is such a thing with you, but if I can not help with an address and if there are no parts which are those that can leave his well coating.

I use this coating already several thousand hours of pressure in all my printers. but I also want to say that I as now wants to sell anything. I'm just a user, but it already was allowed to test the first prototypes and still in use.

Now I just hope that what I have written here can read and understand .... smile

Greetings Edwin

What machine /hot end are you using .
is your hot end fan working?

My printer can print ABS fine, when I load my PLA in it extruders for about 30 seconds then jams in the hotend. I think the PLA is melting too early in the barrel. Any thoughts?
