40mm Fan Cover with Bar for 100mm LED Light Strip by itrdc5

Last crawled date: 3 years, 1 month ago

There are quite a few LED light bars out there but most are very low which makes it hard to see the nozzle. I like seeing what the nozzle is doing, so I mounted the bar a little higher than most.

How I connect my RGB LEDS:
I use RGB LEDs that are controlled via Octoprint using the LEDStripControl plugin. https://plugins.octoprint.org/plugins/ledstripcontrol/
To connect the Raspberry Pi to the LED strip, I followed as per the article below.http://www.instructables.com/id/Easiest-RGB-LED-Strip-With-Raspberry-Pi/
(ignore the shell script as we are using LEDStripControl)
Once that is setup, you can test the light by sending it M150 gcode commands.
You can then insert these commands in your start and end gcode.
Example of my Cura Start Gcode below:
M150 B255 ;blue LED
M190 S{material_bed_temperature} ;Wait for bed temperature to reach target temp
M400 ;wait for current moves to finish
M150 U255 R150 ;orange LED
M104 S{material_print_temperature} ;set the extruder temperature and continue on
M150 R255 ;magenta LED
M109 S{material_print_temperature} ;Set Extruder Temperature and Wait
M82 ; absolute extrusion mode
M400 ;wait for current moves to finish
M150 R255 U255 ;red LED
G21 ;metric values
G90 ;absolute positioning
M82 ;set extruder to absolute mode
G28 ;home
M400 ;wait for current moves to finish
M150 U255 ;green LED
G29 ;auto level
G4 S10; wait for heaters to recover
G1 X0 Y0 Z1 F3000 ; get ready to prime
G92 E0 ;zero the extruded length
G1 X100.0 F500 E40.0 ;start purge line and extrude 20mm
G92 E0 ;zero the extruder
M400 ;wait for current moves to finish
M150 255 ;white LED
;M150 R U B ;LED off
