    What do you think is the cause of the material looking like this?

    The upper end of the scale is least tension, the lower end is most tension. the plug with the indicator sits ontop of the tension spring and is pushed down against this spring by the set screw.

    What do you mean with jacking? Is the stepper motor skipping (this would be a sign of to much tension), or is the filament slipping (to little tension)?

    Do the markings on the filament look like this?

    As I'm getting at my wit's end, adjusting the tension gradually to the point where the filament is extruded through the nozzle and the feeder has a good grip is the only thing I can suggest.

    Regards

     

    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!

    For the UM2+ / UM3-feeder and newer, the middle position is told to be the best, and as the UM2 feeder is very close to the UM3, I'd say try middle position. Light markings on the filament show good tension. If the markings are very deep, reduce tension (scale: up), if it's grinding the filament (like your starting problem), the tension might be too lose, referring to CNC Kitchen's video.

    Regards

     

    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.

    Hi,

    it might be off topic, but your feeder is assembled wrong.

    the head of the set screw for the feeder tension must be inside the feeder housing, your's seem to be outside.

    That for the feeder tension is incorrect, the indicator normally is placed mid-scale.

    Regards

     

    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:

    I will update how it went after I'm done.

    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!

    Printer stuck when trying to print two colors

    in UltiMaker 3D printers

    Posted

    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.
