You need to add a subprogram in the program events with the extruder value (generally a filament length or speed) and create a subprogram on the controller capturing the value and executing it without blocking the main process.
在一天结束的时候,这应该被添加到post-processor if you want to automate everything, but to get started just write down the code and copy/paste it into the code generated by RoboDK.

"How wan we setup extruder like external axis ?"
What do you mean by that?
