Dual extruder prime tower problem


Recommended Posts

Posted · Dual extruder prime tower problem

I have printer with two extruders and one nozzle. How to set Cura 3.6 so the printer on the first layer will print prime tower with extruder 2, on 2 layer with extruder 1, on 3 layer with extruder 2 etc...? Curently it is printing half of prime tower with extruder 1 and the other half with extruder 2 on every layer.

    Are you saying it does the print correctly?  But the prime tower wrong?

     

    Are you saying it's trying to heat a second extruder for the prime tower but there is no second extruder?  Or are you saying it applies an X/Y offset when printing the second nozzle?  Please be more specific about the problem.

    I mean it prints with red filament, then changing layer, printing purge cube with red filament, printing model with red filament, changing to yellow filament on the other half of purge cube, printing model with yellow, changing layer, printing purge cube with yellow etc.... Printing purge cube after layer change is waste of filament

    But that's the way it works, I think there is no way to change the behavior. You can ofc turn off the prime tower, which works in 90% very well, so it is often not really needed. Give it a try.
