Is there a way to have Cura switch extruders during a print for a couple of layers and then switch back to the other extruder(I have a UM3)? I wanted to use it on the drum pictured to print the drum skin a different color then the drum body. I haven't seen how to do it yet. Thanks for your help.

    I'm not sure what you mean by helper volume. Could you explain it to me.  I searched through all the settings and didn't see anything related.  

    Thanks Dim3nsioneer

    Simply use an overlapping "modifier mesh" and select a different extruder for it.

     

    If you don't want to model your own, you can "misuse" the support blocker mesh like shown in this video (just select the other extruder instead of modifying any settings):

    Gave it a try. The color I used for the drum skin was just for a test. I had to lower the height of the support blocker to .5mm and then assigned the other extruder to it and set what settings I wanted. it came out pretty good for a first try. thanks for your help.

    I'm still struggling with this. I cant seem to select an extruder when selecting the settings to modify for the mesh?

    With the modifier block selected just click the other extruder on the bottom left. Don't forget to uncheck "Infill only" in the modifier settings. 

     

    I made a quick video of the process:
