Now it is printing with both filaments. If you do not want to change the ratio to 50/50 manually,
go to Simplify3D, edit process settings, scripts, layer change script and type G93 R50. If you
save this setting, each gcode will start to print with both motors on 50%.
J. Why is there already filament inside the print head when it arrives?
Every Builder Extreme is tested for 50 hours. These tests are done to make sure the printer
works correctly and that the print head is able to print mono, dual and color mixed objects.
The filament stays in the print head for safety reasons. When the Builder Extreme is pre-
heated, you can remove the filament one by one and refill it with new filament.
