Hello,

I currently control extrusion on my Arduino-based 3D-printing toolhead using digital output signals, which only allow start/stop control. This causes the extruder to run continuously during printing.

Currently, I need stable extrusion control. From the documentation, it seems I should switch to an analog output, please correct me if my understanding is incorrect. My main confusion is how to modify the post-processor script to output proper extrusion values for the toolhead (mounted on JAKA Zu20). 

Any guidance on the correct approach and required post-processor changes would be greatly appreciated.

Thank you!

You could integrate an extruder head in many ways, such as using digital outputs, analog outputs or serial communication.

You can achieve a custom integration between the robot controller and your Arduino-based extruder by customizing your post processor.

I recommend you to take a look at the documentation related to robot machining and 3D printing for an example:
