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

Device
The outside of the 3D printer should only be cleaned with a soft, dry cloth or brush.

 Never use any aggressive cleaning agents or chemical solutions on plastic parts, stickers or the display since these

parts would be damaged otherwise.

Outside cleaning of the nozzle:
Carefully wipe off the extruder nozzle after each print using tissue paper or similar.
The nozzle still has to be hot for this. If this is not the case, heat up the extruder nozzle first.

Inner cleaning of the nozzle:
Heat up the extruder and actuate the manual feed forward and backward several times until enough filament is extruded.
If the extruder continues not to extrude enough material after this procedure, let the extruder cool off to the lower melt tempe-

rature of the filament as indicated by the manufacturer (filament material must only be viscous anymore) and carefully confirm

manual infeed backwards until the filament has been transported out of the extruder, including contamination. Cut off the conta-

minated part of the filament and reinsert it after heating up the extruder again.

Clean and degrease the heating plate thoroughly with a soft rag and some acetone after each print.

If you have to replace the fuse, ensure that you only use fuses of the specified type and rated current (see “Technical Data”) as

a replacement.

•  Unplug the mains plug from the mains socket and disconnect the low-voltage line from the low power device combination so-

cket at the rear of the device.

•  Using a suitable screwdriver to push the fuse holder out of the low power device combination socket carefully.
•  Remove the defective fuse and replace it with a new fuse of the indicated type.
•  Carefully push the fuse holder with the new fuse back into the low power device combination socket at the device.
•  After this, you can reconnect the device to the mains voltage and take it into operation.

•  Check the tension of the drive belts now and then.
•  If required, retention them by setting the belt tensioner with the setting screws so that the toothed belts can still be twisted by

180° easily with two fingers.
