Ultimaker Classic, w heated bed...

I have an unusual problem that has plagued me for days.

The observed symptoms are after a few layers the filament feed starts slowing to eventually no feed over one layer.

The temperature (on LCD) seem OK for Nozzle and Bed (245, 100) but as the nozzle travels across existing tracks it grinds through (not melts through), suggesting the nozzle temperature is incorrect. Looking at the filament at the feed mechanism shows a grinding of the teeth on the filament.

I have:

- changed Nema 17 motors (thinking the motor may have lost power)

- assessed and cleared extruder as functioning

- changed the circuit board on the hot end

- changed the K type thermocouple

I did not have a spare heater element to verify this part. Does it look like the heater element has gone? Why would the nozzle temperature be misreporting?

Thanks,

Nic

      • 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.
