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

thingiverse

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. https://www.youtube.com/watch?v=_v4MwDbYeC0 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 M117 Now Printing ;display message
