Attach the LED strips
Add 2 clips onto each LED strip at
about two centimeters from each
end, as shown in picture.
g. 11
Add a piece of double sided tape to
each clip. (for your convenience, do
not remove the upper layer of the
tape yet)

Solder the white cables to the coloured
cable as shown in the picture.
Mind which cable is soldered to the
other!
- green wire to white wire with
full black line
- red wire to white wire with Xs
- blue wire to white wire with dotted line
- black wire to white wire with symbols
Slide the shrink tubes over the soldering and heat them with a hairdryer or
heatgun to make them shrink.

K8403USER MANUAL
Control the LEDs with a G-Code
With the M420 code you can control your LED add-on trough G-Code.
1) standard code: M420 Rx Ex Bx
2) x can be 0 or 1 to turn a color on or off
3) R = Red, E = Green, B = Blue
Not all values are needed, if a value is missing the previous state of the missing color is kept.
1) M420 R1 E1 (turn the red and green LEDs on, don’t change the state of the blue LEDs)
2) M420 B0 (turn off the Blue LEDs and don’t change the state of the others)
Example with Start G-Code in Repetier:
M420 R0 E0 B1; Set the LEDs to blue
G28 ; Home extruder
M420 R1 B0; Set the LEDs to red
G1 Z5 F{Z_TRAVEL_SPEED}
G1 Z0 F{Z_TRAVEL_SPEED}
M106 S165 ; Turn on fan
G90 ; Absolute positioning
M82 ; Extruder in absolute mode
; Activate all used extruder
{IF_EXT0}M104 T0 S{TEMP0}
{IF_EXT1}M104 T1 S{TEMP1}
G92 E0 ; Reset extruder position
; Wait for all used extruders to reach temperature
