[ Manual N2＆N2 Plus - How to Install the Filament Run-out Sensor -V1.0 ]

Contents:

A. Filament Run-out Sensor. 

B. Filament Run-out Sensor Cable. 

C. Adapter.

D. Bowden Tube with 4mm-OD *2.

E. Cable Tie *4.


1. Turn power switch to the “0” or “Off” state. Once the printer has fully shut down, unplug the power cable. 


2. Remove the back panel of the printer with a phillips head screwdriver. The attached side door will also be removed with this panel. Set the panel and screws aside. 



3. Remove the 4 fixing screws with a 2mm hex wrench.  

 

If your model does not have visible screws, this cover may be removed by utilizing the push tabs that connect the cover to the frame. 


4. If your printer model has a covering for the wire-path behind the electrical box, remove this covering. (See Left) If there is no removable cover on the wiring guide tube of your printer, please inset the end of the cable into the gap between guide tube and bottom cover. Then drag it into the electronic box. (See Right) 


  • Pass the white Filament Run-out Sensor cable through the wire path along the back side of the machine.
  • Feed the end of this cable down under the printer and loop the cable back up into the electrical compartment.


Use the included adapter (C) to connect the Filament Run-Out Sensor to the motion controller board with the 4-pin end. 


Attach the other three ends of the adapter onto the Motion Controller Board as shown in the following pictures:

Red-black cable to EXP3 (slot on terminal face to right),

White Cable to Y+,

Green Cable to Z+.


Wiring complete: 


6. Assemble the Filament Run-Out Sensor 

Connect the white Filament Run-Out Sensor cable (B) to the Filament Run-Out Sensor (A). Remove the tape covering. 


7. Check the Filament Run-Out Sensor function

Power on the printer. Check whether the red lights on sensor are on or not with no filament passing through the sensor. If the lights are on, please power off the printer and move onto the next steps. 

If the lights are not on, please contact support at help.raise3d.com.


8. Replace the Bowden Tube

1) If the original Bowden Tubes on your printer are with 4mm-OD: 

  • Remove the original Bowden tubes completely and replace them with the included Bowden tubes from the Run-Out Kit (D). To release the tubes, press and hold the blue ring on the coupling.  


2) If the original Bowden Tubes on your printer are with 6mm-OD: 

  • Keep the origin tubes and directly insert the new 4mm–OD tubes to pass through. 


9. Install the Filament Run-Out Sensor

Insert the Filament Guide Tubes into the two holes located at the end of the guiding paths of the plastic back cover. And fix the tubes into the guiding paths.


Adjust the height of the sensor until the top screw is hidden by the body of the printer, and the top of the bottom screw lies flush along the panel.

10. Load filament through the Run-Out Sensor and up through the Bowden tube to make sure the filament path is assembled correctly. 


Note the filament feeding order for each nozzle to prevent false alarm. 


11. Re-attach the components that have been removed. This includes:

  • The Wire-Path Covering (Step 9)
  • Motion Controller Box covering (Step 8)
  • Back Panel and door (Step 2)


12. Please download Motion Board Firmware with FRS version from https://www.raise3d.com/pages/filament-run-out-sensor-installation-instruction and Version 0.9.7 (or later) Touchscreen Firmware from https://www.raise3d.com/pages/download. Save the two firmwares in USB storage. Attach the USB storage onto the screen and reboot the printer. Continue to the “Motion Controller Firmware Update” for instructions on how to update to the motion board firmware.
