Hello, i have a probkem with my reprap and i can’t print because of it. My PLA filament is curling inside the hotend and not comming out from the nozzle. It is very hard to push it like it is not hot enough. I am extruding at 230 and nothing comes out. Can the filament be ABS not PLA. On the package it says PLA.
Heat is your problem. Heat is rising up in your hotend and melting the filament too early, making it to curl like your first picture shows. That’s also the reason that E3D Hotends (look them up) have a fan blowing at 100% at the hotend all the time. You want to have a hot zone at the bottom, and a cold zone at the top of your hotend.
What kind of Hotend do you have? A picture could help.
It sounds like something is jammed up. Did you take off the nozzle to see if the path is clear ??
Abs would still extruder at 230 c.
your hot end is likely clogged, heat it up and push a piano wire up into the nozzle and “push” the clog up and out the extruder top. You may need to remove extruder drive to get the rollers out of the way
read the manuels ,and learn what to do with clogged hotends , more info is also plaesed .
my car is not running is not an much info??
see e3d troubleshooting and “cold pull up” method.
cleaning your hotends is very important,
hope you learn it .
cheers

SOLUTION Its a simple problem. All you need to do is insert a PTFE tube in the extruder throat. This will solve your problem… Guarenteed. PS: It goes without saying that the extruder fan must always be on. Could you please do this and confirm your result here.
Looks to hight for PLA, I use about 195ºC,
About the curling, does your hotend have a fan? if so is it on?
Looks like the heat is passing the heatbreak up the barrel
Mike,
Rather than being an ass, why not ask for the information that would be helpful?
