Switch extruder at a specified layer

Recommended Posts

I am trying to print a two colored medallion and need to switch colors at a specific layer. I tried using one extruder and the change filament plugin. It sorta worked, only issue was when I hit resume it started extruding above the print. Since my UM3 has two extruders, is there a way to get Cura to switch extruders at a specified layer.

Normally you have to design your object in two parts. Then you import every part into Cura and select which extruder should print the selected part. Then you merge both objects together and they automatically move to the original position they had in your CAD software, to get again one combined object in Cura, but with different settings (extruder).

obviously @Smithy's solution is the safest, but I see no reason why you can't just set the toolchange manually in the Gcode file. If you want to look at the way the UM3 handles the gcode just slice a tiny dual print (stack two smal cubes) and look at the gcode around the layer where the change occurs (use f.e. Notepad++ to change the gcode files). Look at codes like T0, T1 (set active nozzle) and M104, M109 (set temperature)

 

edit: save to / print from USB if you manually alter the Gcode

 

And read here for more on the UM3 Gcode;

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
