Description
The LEDs along the top sides works nice for looking down on the build plate, but the print head itself is not well lit. This is especially a problem after I moved the printer to a location with poor ambient lighting. So I used some more of my LED strip and added these to the front. Since its a Trident I didn't want to use the other solutions I found for the 2.4 which cover the whole front, or are not shielded from the top. These LEDs fit nicely below the front belt tensioners on each side and are out of the way. I connected them to an open heater pin on my mcu so they can be controlled separately from the side LEDs.
The height of the LED holder matches one section of the LED strip between cut lines, and you can scale in z direction to change. If it doesn't fit your extrusion you can scale in the X-Y direction.
I turn on these LEDs at 50 percent power and leave them on. It helps remind me that the printer is on without using much energy, and makes cleaning the print bed, removing parts, and loading/unloading filament easier.
I use the Klippain macro project, and added this to my overrides.cfg file (along with the corresponding pin in my mcu,cfg file):
#-------------------------#
# FRONT LIGHTS #
#-------------------------#
[output_pin frontlight]
pin: LIGHT_FRONT
pwm: true
value: 0
scale: 100
cycle_time: 0.010
[gcode_macro _INIT_USERCUSTOM]
gcode:
# Turn front lights on when printer is started...
SET_PIN PIN=frontlight VALUE=50.00
