Press the upload button and the filament will come out.
Pressing the load button returns the filament.
Why?
The same symptom is observed for both the right nozzle and the left nozzle.
The firmware is the latest V.2.0.16.
Are there any users with the same symptoms?
I tried the laser module.
The laser module also gave an error.
I think it does not recognize the camera.
In the Integrated Controller, both the laser module and the Dual Extention Module are correctly recognized on the LCD screen.
There is a possibility that the “Integrated Controller” or “Toolhead Cable” is defective.
The X, Y, and Z axis modules are working properly.
