New driver, laser not turning on?

[Vision]

I was using a flashlight driver for it and just got the X-drive, but its not turning on? Something wrong with my setup or something?

I'm using the ehgemus host as contact points, so its not anything else.

does it read with a test load?
what batteries in the host? Ive done it that way and sometimes get issues with weak contacts.
do you get voltage at the v+/V-?
what diode? what did you set the driver to?
and is that just taped together or is the tape used as temp insulation?

Looks like there is solder splash between + and - on driver output

Darn Ultron,
You are snake bit lately. You need to get a test load, impossible to diagnose without it

I would also invest in some heat shrink tubing. That yellow tape has got to go. It's an accident waiting to happen.

Don't have one yet.

2 x 18650. Tried with 2 different host, still didn't turn on.

No idea, don't have a test load.

Its a 2.4A X-drive, I bought it from DTR

Its soldered underneath.

Yeah, I really do.

I do have them. Just used that temporarily to see how the driver was working.

Those solder pads look like they got pretty hot as well..

Hi,
Is this driver an adjustable with a pot or a fixed driver??

I think its fixed? I don't see a potentiomenter on it.

Do you have a multi-meter? If you can get it laid out, and get the meter probes on the LD + and - and power it on, you can at least see if there's any voltage going through the driver. But that's about it without a test load, or a different driver/diode to swap out.

I don't, I'm sure an engineering student will have one. I'll try and find one.
