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.
