Controlling cool down timing of nozzle in dual extrusion


Recommended Posts

Posted · Controlling cool down timing of nozzle in dual extrusion

We are trying to print PA-CF in combination with Aquatek X1 support material on an Ultimaker S5. It almost works but we are seeing issues with oozing of the nylon filament when extruding the support material.

The settings are 265 C printing temp and a final print temp of 250 C. It seems it correctly times the cool-down so that the final lines are extruded at 250 C, then it switches nozzle and moves to the prime tower. Here the first nozzle starts cooling towards the stand-by of 220 C. During the priming of support nozzle ,the primary nozzle has oozed about 5 mm of filament which remains stuck on the nozzle while printing the support. Sometimes is gets loose in the print, sometimes it will remain on the nozzle until next layer.


Setting the end temperature lower could probably solve this problem but it doesn't seem to be the correct solution. Perhaps the best would be to have the nozzle cool down to stand-by and then wipe it on the prime tower before changing nozzle.

        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.
