Problem with prime towers and multiple extrusion


Recommended Posts

Posted · Problem with prime towers and multiple extrusion

I am using a Sovol SV-04 printer, which is an IDEX printer. When it goes to print the prime tower, the second extruder is only printing the priming material on every other layer. (See screenshot). This is causing the second material to effectively print on thin air, which is causing the material to form globs on my hotend and stick to the side of the prime tower. In rare cases, these globs stick upward enough that the nozzle from the other carriage crashes into them and knocks the prime tower over. It is knocking the tower over even when I am using a very sizeable brim.


Is there some way to make Cura print the prime tower on every layer? I am using Cura version 5.2.1.

        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.
