Nozzle Temperature Decreases While Printing? :(

Hi friends,

When Ultimaker is printing it first sets the true 210 Celcius to temprature. But while printing temprature decreases and at below 200 degre.. 3d print starts to underextrusion because of higher viscosity.

Why it happens? It should stay at 210 degree or which degree that I set.. :(

Temperature drop

 

At image temperature drops to 195 degree.. and everything fails.. :/

    I don't understand either of the last two suggestions. If the fans are causing a temp drop (which they surely must) then shouldn't the heater controller function compensate? At 210 it surely isn't already 100% on?

    Yes problem is at fan I realised.. But before last update there were no problem. It was compensating itself. I reduced Fan speed %100 to %30. And now makes no problem. :)

    Thanks friends.

    If the fan speed is set too high the heater can't keep up with the heat loss, particularly at higher print speeds, where it has to heat more plastic.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
