Renkforce 3D printer RF1000 Single extruder (value.974113) RF1000 Data Sheet

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:

The 3D printer does not work after switching on. The display and print space lighting remain dark:
•  Check the connection of the mains line.
•  Check the mains socket. Is it properly supplied with current?
•  Check the mains fuse (also see “Fuse change” in chapter “Maintenance”).

No USB connection to the 3D printer is possible:
•  Check the USB line connection.
•  Is the right USB port selected in the software?
•  Are the required drivers installed?
•  Unplug the USB line and then plug it in again.
•  Start the software again.
•  Switch the 3D printer off and on again.
•  Start the computer again.
•  Use another USB port.
•  Connect the 3D printer directly to a USB port of the computer. Do not use any USB hub.

Calibration of the heating plate stops. The display shows the message “Scan aborted”:
•  Heat the extruder to melting temperature of the inserted filament and transport the filament a few steps backwards out of the

extruder. The filament must not cause any forces to be exerted on the extruder but the ball bearing holder still must be loaded

by the filament.

•  The extruder nozzle must be clean from the outside (if required, heat and wipe off first – caution: hot nozzle!)
•  Perform the basic settings of the limit switch for the Z-direction again. The plate distance must not be too large.
•  The pressure sensors may have been installed under tension. In this case, loosen the screws of the print sensors and then

retighten them evenly.

The print has defects:
•  Check the extruder and heating bed temperature settings. They must match the filament material and print object. Experiment

with the temperature settings in steps of 5 °C for a prefect print result.

•  Only start the print when the extruder and the heating bed have reached the specified temperature.
•  The distance between the heating plate and extruder is set incorrectly. Perform Z calibration or set the distance more precisely

when starting the print using the buttons at the 3D printer.

•  When printing from the PC, do not use any other programmes requiring high computing power. Virus scanners and downloads

may also impair signal transfer to the 3D printer. Try performing the same print from the SD card to ensure that the USB connec-

tion is not the cause of the problems.
