When properly assembled, the screws do not cause a short.
However, in your case, you are getting a short. One possibility is that by screwing and unscrewing your screws the bottom of the screw heads ground through the layer of paint on the top of the MPCB under the screw heads. If that grinding went through into a trace then there could be a short. I do not know offhand if the MPCB used in the D4 has traces near the holes, but if it does, that could explain why you are getting a short.
So ive been scouring this thread debating on the typical emitter choice and for a while I had planned on a 3k SST20 because I want this specifically for late night walks and candle mode (once I flash Anduril) but the green levels at low current are making me rethink my choices.
I dont really want to spring for the XPL-HI 5D if I dont need to, but green tints are a hard stop.
Anyone have one of the 3k SST20 models?
All 3000K SST-20 leds I have used sofar are not green in any optic or current.
I kinda feel like an ass, but I just ordered a D4 with Anduril flashed and 3k/4k tint mixing. I have the capability of flashing an ATTinyXX, but I really dont want to mess with beating the driver out.
Go big or go home right?
I just hope the green levels arent noticable.
Ain't nothing wrong with any of that! Heck, my phone has dual tint flash so why not with our light cannons?
Now, I want to ask Hank to change my order to dual LEDs!
my current edc D4 has 2x 3000k dome on and 2x 4000k dedomed sst20 emitters.
tint is perfect. no green and rosy on high levels
anduril and aux leds as well, of course 
Hank will do the D4 or D1 with Anduril flashed ? If so, I’m probably going to get another D4 or a D1. I flashed my D4S to Anduril, but haven’t got the skills to do the solder work on my D4.
I finally relented and bought an Emisar D4. got the XPL 5K. Question, if I were to ask nicely, you think Hank would flash Anduril before shipping? Or I’ll just have to figure it out myself on my own?
Anybody in the San Francisco bay area know how?
I like the idea of a stepped option rather than just ramping.
Probably depends on how long ago you ordered it. Send an email, today, so he'll likely read it when he wakes up. He's been very responsive with me but we started the conversation before I ordered.
I apologize if I overlooked it, but does anyone know what Anduril step full regulation is on the D4?
I’m not sure if I understand the question, but maybe the D4 config file has the answer?
I was thinking he meant which step level is 7135 with no PWM and no FET drive on.
Ah, just saw it.
#define MAX_1x7135 65
Yep, this.
I wanted to set the max ramp in Anduril to the highest, fully regulated “step”
So I guess thats 86 clicks. (151-65=86)
Edit: im just wondering, do the SST20s need limited to 80% FET like the 219Cs?
No, they don’t.
They don’t have as low of a VF, so current is limited already.
Clip didnt work, had to bend it, but it just snapped. Any good clips, black plz?
UPDATE:
rubber button that is more “recessed” is now slightly unresponsive… clicks dont register as well as it used to. sometimes when you double click for turbo, the light wont go to turbo. you have to do it again. the clicks are not as “loud” as it used to also… avoid the ones with recessed rubber switch if possible…
I just received my new Anduril flashed, tint mixed D4 from Hank. Aside from being downright awesome, I just noticed that my driver has flashing vias. Not sure if ive ever heard or seen these in the wild yet.
https://i.imgur.com/pF9MN3I.jpg Its a tad out of focus, but you get the idea.
Nice! looks like Hank updated the D4’s driver board to include flashing vias! 
That is fantastic news, and I think I will have to get one. The D4 is the most overpowered unmodded light I’ve encountered, so it’s sort of a worst-case scenario for thermal regulation. The ability to reflash it without taking anything apart would be incredibly helpful for thermal testing.
You can order a D4 from Hank with Anduril? Or did you flash it yourself?
