Possible solution
Check that the mains cable is connected properly.
Check the mains socket. Is it supplied with electricity?
Check that the USB cable is connected.
Have you selected the correct USB port in the software?
Are the required drivers installed?
Disconnect and then reinsert the USB cable.
Switch the 3D printer off, and then switch it back on.
Restart your computer.
Use a different USB port on your computer.
Connect the 3D printer directly to a USB port on your computer. Do
not use a USB hub.
Check the nozzle temperature settings. These must be suitable for
the filament material and printed object. Experiment with several
temperature settings.
Do not start printing until the nozzle has reached the required
temperature.
Decrease the distance between the print bed and nozzle (see "a)
Calibrating the print bed" on page 29).
When printing via your computer, avoid using other programs that
require a lot of computing power. Virus scanners and downloads can
affect the transfer of data to the 3D printer. Try printing the same model
via the SD card to check that the USB connection is not the cause of
the problem.
Remove excess filament from the nozzle before each print.
Check the filament spool. It must be able to rotate easily.
Check whether the filament material has become trapped or wrapped
around the spool/spool holder.
Check that the filament was inserted correctly over the filament spool.
Check whether the nozzle temperature is too low for the filament
material.
Check whether the nozzle is blocked. If necessary, clean the nozzle
(see "b) Cleaning the nozzle" on page 56 for details).
