Extrusion control with multiple extruders
-
Hi,
I am trying to configure a dual extruder / dual heater / single carriage printer.
On DWC heater control is ok, I am able to control each heaters individually, but not "Extrusion control". I can control one of the extruders, but not the other.
What am I missing?Config.g:

@scaulier the extrusion control in DWC just controls the active tool, switch tools to control the other one. If you want to extrude from both at the same time then combine them into a single tool.
