I can’t get my second extruder to work.
In printer settings i choose 2 extruders. But every time he starts printing with extruder 1 (right).
In Cura i have no problems.
I have it working. In slices you don’t need to set the settings to 2 extruders. Just before starting the printing go to the Manual tab and choose the other extruder.
even if it is an “old” post:
check the settings in the “print settings” in the group “multiple extruders”
Here you can select which structures are printed with which extruder.
For only switching the printhead you change all values to “2”
