1.6W 445 Mohrenberg 18650 Host+Heatsink Kit Review + Tutorial

[Mohrenberg]

I also sell simple focus adapters that will fit this host for $10.

@DTR: I noticed that you wrapped the driver in electrical tape. Should I do this with the flexdrive I am using in mine? I am using the same host and you set it to 1.5A

If you are not sinking it to a coin you would wrap it but you would want to sink it since you have it set to 1.5A per the second build in this tutorial.:beer:

If I do just wrap it instead of doing that mod, how long should the duty cycle be. I probably wouldn't run it for more than 1 min or so at a time.

a minute would be fine, unless you have a really small heatsink, or a REALLY high current, then i doubt a minute duty cycle would harm any laser really

It may run from 20 to 40 seconds. For a flexdrive set to 1.5A the driver will overheat very quickly unless you sink it.

oops, i was talking diodes... i didn't know we had moved to drivers.

I just put mine together and the dot is huge. It's more like a flashlight. How do I fix this?

You just need to turn your lens to focus it.:beer:

Unless you don't have a lens in it yet.:yh:

It focuses some but it still is closer to a flashlight. It's like the lens is too close to the diode. I'm using an axiz 405 lens I bought here:
405nm glass lens for AixiZ 12X30mm laser module - eBay (item 380137309450 end time Jan-28-11 12:34:45 PST)
I have a feeling I bought one that was too long.
When I have it the furthest it can be from the diode it is the best, and if I unscrew it more, then it just falls out of module.

 

[jakeGT]

is your module set flush with your heatsink? because that is the common glass lens for 405/445 that we use around here and should be the perfect length for your build.
If you have the aixiz module that has your diode in it set to far back or too far forward that would most likely be the problem I do believe. sounds like it at least to me

Once again, is your module flush with your heatsink? that should be perfect for all the focusing you need

Yes it is perfectly flush with the heatsink.

 

[jakeGT]

are you positive you have the lens inserted the correct way? like not ass backwards?

if that is not the problem, then try setting your module back farther in the heatsink, in DTR's pics it looks as if his is focused to infinity but the aixiz focus knob is almost right up against the heatsink. I could be wrong though, but try it out, try setting ur module a little farther back in the HS, if not good, try a little farther, if still not getting better... im out of ideas!

EDIT: nevermind. Just because the other end couldn't be screwed into the Aixiz focus ring, didn't mean that it was backwards. It works that way..... Wow, I feel stupid...

 

[Aaron]

I just got mine in the mail today
One question: How do you get the heatsink out of the head? mine seems to be stuck...

 

[Aaron]

Nevermind, I got it out

 

[Mohrenberg]

nah, It's just a REALLY good fit
