22.Troubleshooting
With this 3D printer, you have purchased a product that is built to the state of the art and operationally safe.
Nevertheless, problems or errors may occur. Therefore, we would like to describe how to eliminate possible errors here:
Alwaysobservethesafetyinformation!

impair signal transfer to the 3D printer. Try performing the same print from the SD card to ensure that the USB connection is not the cause of
the problems.
