Yes, exactly. The motor is skipping. Now the material wouldn't even eject from the feeder. I will probably give up on this printer and just assume the feeder is broken. Thank you so much for your time and expertise!

Now as soon at the material is fed all the way the feeder is just jacking, unable to feed it through the printhead. I have tried the atomic method to get rid of some filament that was in the printhead, so it's not blocked. Do you think this is a separate issue, or is it caused by too lose tension? I should explain more in depth, the feeder does accept the material with some help, then it gets to the print head, at which point it stops revolving, and instead makes a jacking motion. It's like the feeder is too weak to properly feed the material anymore.

Thanks!

Thank you so much Enigma!

Since it's not my printer I can't do anything more.

This is what the manual for the printer says to do, but I am unable to do this because the tension screw is mounted wrong.

Now that I've taken a closer look, I see what you mean by that the tension screw is mounted wrong.

Thanks for both your posts. This issue occured with other filaments too, so it's probably that the feeder is set to feed too tight, so that it ground down the filament instead of feeding it. I will attempt to decrease the tension that the feeder gives. I found this guide on how to do it: https://support.ultimaker.com/hc/en-us/articles/360012015880-Material-is-ground-down-by-the-feeder I will update how it went after I'm done.

The material is completely stuck in the tube, I can also feel it's brittle, so I suspect the material has been improperly stored.

I took a closer look at the feeder and it's full of crumbled plastic. This leads me to believe the PLA-plastic was old or dried out. Do you think this is a correct guess?

Hi! I would greatly appreciate if anyone can give their input on what could have caused this. I printed using my red material (PLA 2.85 mm) in an Ultimaker 3 and it completely jammed the machine after two prints. I had a lot of projects to do so I started using another printer (an Ultimaker 2) and it worked fine until I used the same spool of red material and the Ultimaker 2 got jammed the exact same way (nothing came out of the printhead). I then suspected it might be the material and I looked how the now jammed material looked, and I noticed small dimples accross where the material had been fed into the machine, as well as two giant indentations that the wheels of the feeder must have dug into the material. Is it possible that this material is too old and this causes it to break when the machine is handling it? I read that PLA has a shelf life of 2-3 years. Thanks for any input!

Thanks tinkergnome! Works perfectly now.

I have an Ultimaker 2 extended+ and I have tried to print a model in two colors according to the attached youtube guide. When I get to the part where I am suppossed to insert new material, the 3D-printer gets stuck and the message "cooling printhead for material insertion" and "heating printhead for material insertion" flickers on the screen and it doesn't matter how long I wait. The fans on the printer head are fully on when this happens. The 3D-printer works perfectly at all other times and I have no problem inserting new material. It's only when I pause the printing midway through that I can't insert new material. Has anyone else experienced this, and is there a fix? I would greatly apprichiate help.
