    Set Fan on result in "under extrusion" (U2+)

    in UltiMaker 3D printers

    Posted

    Hi, i thought it was enought put printers type in the topic. I‘m sorry!

     

    ultimaker 2+

    Filament: pet (innofill), petg (two different brands)

    I think it is not depending on filament because i print this filaments without this issue in former times.

    At least one role was new shopped.

     

    I forgot to tell, that increasing speed shows the same result...

     

    and if i set the fan on, i cannot compansate the missing extrusion by increasing the extrusion multiplier...

    i tried values more than 140% multiplier and temps over 10 degree over the  specs.. it didn’t  help.

     

    the printig speed i can use is very less 60mm/s.

     

    but please keep in mind:

    the tempsensor vealue shows good match with low variations. Temp “seems” to be fine...

    Hi Community,

     

    I got the problem if fan is set on it result in under extruision. never had this issue befor but for 3 weeks i had it each time. So i stop using the fan.

     

    It looks like the filament is not heating up enough if fan is set on. But the temp sensor (or Ulti's display) says a constant temperature. Cause that i am confused.

     

    First option in my mind is to replace the heating bullet. But i don't want wasting money and time to replace a working heater.

     

    Maybe someone is familiar with that issue.

    I would be happy about helpfull infos.

     

    Best regards

    Peter
