Ultimaker cura S5 - material jammed, unload doesn't work

[CJ_Exit 0]

Hello,

 

Today i printed with tough PLA on core 1, in middle of printing printer wrote something about noo having enough material in material storage coil, but there was plenty of it. After it i aborted printing and pressed unload material on printer, but material is still in tube and core, it wont take it out. Do you know why? Or do you have experience with it? Can someone help me please?

 

 

1. printed aborted

2. unload material failed

3. unload material after trying again and again still wont unload string.., and also after unloading printer shows that material is not in loaded... 

 

 

Thank you very much,

Hi @CJ_Exit thank you for your post and welcome to the forums! When the print volume decreases by around 80% the error shows up saying there is not enough filament. In the future we intent to make it a little bit clearer about a possible cause, but for now let's look at your symptoms. You mention that the material is stuck in the print core, or at least seems to be. Did the material grind at the feeder, and is that why it can not pull it out, or is it stuck in the print core?

 

When your filament got stuck in the print core, most likely your front fan stopped working and therefor it couldn't keep your print core cool enough, and the heat traveled up via the filament to a point where it could expand. And now it is stuck. 

 

You might be able to pull it out manually when the print core is heated, and the filament softened a bit. But make sure to check if the fan works. If it doesn't, the cable might be pinched or there are might be small strings of filament in between the blades that prevent it from spinning. 

 

Hope this helps!

How about telling how to do that?    I had to fool the machine into heating the core up by using the cleaning process.
Also, the feeder should be disassembled to assure that the grip wheel isn't fouled with material dust.. often happens when there is a jam and that will wreak mysterious havoc until it's clean.

Look in the menu. You can select the print head.  This is the same menu as for changing the printhead.   (Look for the three dots in the upper right corner) There you can do -Set temperature-.
