Haven't been here for a long time... Came across this video,thought i share it with everyone. :beer: https://www.youtube.com/watch?v=hcGgaa2mFc4

Well,i'm now using it anymore. It was just for fun. The 808nm cant be really used for something practical. I wanted to use it for a CNC engraver. Finding a lense for this thing and a fiber cable is really hard. The laser diode costed like 250$. Not really that expensive but really not usable for...

Close enough :D

Probably because unplugging from the driver. The only way of fixing it is by buying a new diode. You can see a lot of threads on this. There is a search bar on the bottom of the page. Fill up your location and other info. :)

Looks like a Dead diode. Sorry :)

Google is your friend. Also,there is a search bar on the bottom of the page. There are countless threads about this.

I kako da ne poludis kad vidis ovakve ljude... People these days...

I can only presume that is working for you cause of the foreword voltage drop. If the diode is below its operating voltage,it will draw very little current. So you have maybe found that point... Where did you read about that kind of driver ? Also,dont look at the beam,and dont point it on skin...

Why would you do that... A laser diode is a DIODE! it needs current limiting! The diode is most likely dead. Take a photo of the beam. The reader diodes work at very small currents <100mA.

Wait....directly from 7805 to diode ?

Imagine working there...Drag our beds there and never leave :D

Came across this today,thought i share it with everyone here. That table is pure heaven...:bowdown: https://www.youtube.com/watch?v=drnq_6ffTbo

Its really that simple :) Have fun!

I see two ways. Connecting the pulse input signal to both drivers or connecting two steppers in parallel and driving them with one driver. When connecting 2 drivers on the same pulse line its good to have a sync pin on the driver so they can be perfectly in sync.

2.4k seems ok (depends on the current you want). You can use online zener diode calculator to double check.

Maybe the driver has a sync pin,if not,steppers in parallel can be connected. That could work,try it out :)

Well,its not going to work. First,the blue laser diode works at 5v+ and na IR one is at 2.2v. Second,the lenses are not for that wavelength. You can only use the host,nothing else. Maybe the driver can be modified,but that would be just a waste of time. Better buy the lens and the driver. :beer:

The Big fat red wire goes to the anode of the CO2 tube,the cathode goes to ground(chassis).

Start basic,take it slow,go easy. You cant run if you cant walk. Without knowledge time is wasted. This forum is best on internet,all the information needed to start is here. There is a search bar on the bottom of the page,have a try at it. If you need any help,you can always ask and you...

If this is your first laser,you will see the difference when you get the new one working. I dont need to mention that you need to be careful with the laser? If the laser hits your eyes...you will get blinded. Eye protection is needed. For the driver, i hope you have some good experience with...
