Adafruit NeoPixel Ring 12 Leds Fitting Cover

prusaprinters

<p>I integrated a 12 pixel neopixel ring into my printer to act as a temp gauge when warming up and cooling down, then just a random color fading widget while at temp. I used FKOne's mount as a backing to attach it to my printer. It needed a little bit of a diffuser and I had some glow-in-the-dark filament handy so I made this snap fit cover for it.</p> <p>The result is three 0.3mm layers of solid fill glow-in-the-dark filament and a ring that snaps over the frame. I might add a few more layers later or make it so it stands off of the frame a little further but I'm satisfied with it for now.</p> <p>Let me know if you're interested in my wiring and code.</p> <p><em>UPDATE 8/6/2017</em><br/> Here are the changes I made to my Marlin code:<br/> Add the Adafruit Neopixel library .h and .ccp files to the same folder Marlin is in.<br/> Find the function "void manage_inactivity" and add the following to the last line of the function:</p> <p>"dispTempGauge(); //Call's Dan's temp gauge" Add the following function: (I added it below the Temp_Stat_LEDs fuction)</p> <h3> // // Begin Dan's Custom Coloring!! // // unsigned long previousMills = 0; unsigned long currentMills = 0; int guage_type = 2; //default to display off int guage = 3; void dispTempGuage(){ int8_t cur_extruder = 0; currentMills = millis(); if (currentMills - previousMills &gt; 200) { // Update every 0.2s previousMills = currentMills; if ((isHeatingHotend(cur_extruder)) &amp;&amp; (degTargetHotend(cur_extruder)&gt;100.0) &amp;&amp; ((degTargetHotend(cur_extruder)-degHotend(cur_extruder))&gt;2)){ guage_type = 1; //if heating up &amp;&amp; target is set high &amp;&amp; not there yet } else if(degHotend(cur_extruder)&gt;150.0){ //if not heating and temp is above minimum then dance guage_type = 2; } else if(degHotend(cur_extruder)&gt;30.0){ //when done dancing then show cool down from prev temp setting? guage_type = 3;//busy printing } else{ //if none of the above then the printer must be idle. turn all lights off. guage_type = 0; //lights off } switch (guage_type){ case 0://off for(int i=0;i<numpixels;i++){ 0="" 1="" 1:="" 2="" 20,="" break;="" case="" cold="" degtargethotend(cur_extruder)<em="" green="" guage="map(degHotend(active_extruder)," guagecolor="pixels.Color(map(degHotend(active_extruder),20,degTargetHotend(cur_extruder)-2,0,128),0,map(degHotend(active_extruder),20,degTargetHotend(cur_extruder)-2,128,0));" heating="" hot="" is="" pixel="" pixels.setpixelcolor(0,128,0,0);="" pixels.setpixelcolor(1,0,128,0);="" pixels.setpixelcolor(2,0,0,128);="" pixels.setpixelcolor(i,0,0,0);="" sample="" status="" }="">.99, 3, 11); //maxTemp</numpixels;i++){></h3>.90 is to scale the max pixel down slightly.
