Posted · Sensors malfunctioned? Have to increase temperature for a particular filament considerably.

Using a black filament I've had to increase the nozzle temp compared to white filament to 220 degC, after quite a few successful prints I noticed it would occasionally jam and after many atomic methods to no avail I tried some of the white filament and tried pushing it trough manually and it worked a treat straight away. I figured it must be the temperature and so increasing it to around 250-255 degC with the black filament got it flowing how it was previously.

The trouble I have now is that its leaving strings whilst moving the head - and clearly something is wrong.

How do I troubleshoot this - I'm assuming the sensors are the things I have to check first?

    If the white works but the black doesn't then it sounds like it's a material issue.

    Are you sure the black is Pla?  Maybe it was labeled wrong.

    My first thought also is that the black material might be ABS.

      • Release Notes: S-Line Firmware 8.3.0 (Latest)

        Dustin posted a topic in Firmware,

        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.
