Introduction
Guide on how to add light bars and configue them for use with Klipper. This assumes you have a working printer with Klipper installed and the printer able to move. It also assumes you have a decent knowledge of working with the Klipper configuration files and basic wiring.
Tools
Parts
-
-
Mount your LED light bars with whatever mounts you choose.
-
Make sure the wires exit the bars at the BACK of the printer
-
Your mounts may vary so it is up to you to determine how they mount.
-
-
-
Run the wires out the back of the printer by either:
-
Drilling 1-2 holes in the back panel and feeding them through
-
Drilling hole in exhaust fan housing
-
Connect wires in parallel. Connect both +V wires together as well as both Gnd wires.
-
Extend the group wires long enough to reach the underside of the machine.
-
-
-
Connect the light-bar to the screw terminal labeled D8 on MCU-1 (X-Y-E)
-
-
-
Open up your `printer.cfg` and add the following section:
-
[output_pin caselight] pin: **PIN** pwm: True value: 0.1 cycle_time: 0.001 hardware_pwm: True
-
Replace **PIN** with your pin number below
-
Ramps 1.4 : ar8
-
SKR 1.3 : P2.5
-
-
-
The name "caselight" is built into the Klipper 'control' menu and already contains a menu option for setting the brightness.
-
Manual Control can be had with the following commands:
-
SET_PIN PIN=caselight VALUE=0
-
SET_PIN PIN=caselight VALUE=xxx
-
SET_PIN PIN=caselight VALUE=255
-
