Hi Jack
You know I thought of that when I made my purchase. That is why I bought thru eBay
But because it took a crap after their 30 money back guarantee (45 days), eBay wouldn’t help me at all. eBay said that I needed to go thru them and contact the seller (some version of NEJE).
Then they started to ignore my emails, so I found another NEJE Customer Service email address. The people at the end of the new address told me that I needed to go thru the PLATFORM that I bought it from to deal with problem.
The problem is NEJE posts everywhere that they have the Customer Service and a 2 year warranty. They are liars, sell crap and don’t care about their customers at all.
WHAT ARE WE GOING TO DO ABOUT IT?
Neat, where did the dual diode configuration information come from? I find it hard to believe that any laser has a 38% power conversion, especially these things. The best seem to be about 10%, meaning only about 4 watts out with 40 in. Pumped lasers have a range from 1% to 25%.
I’ve tried using a Mahoney watt meter on mine, but it’s for a CO2 laser, so I’m not sure what to make of it. They said ‘guesstimate’ lol… Appeared to be about 2 watts.
Robert, most things have an limit, otherwise I’d guess it’d be called something else. That’s the problem with those electronics. I purchase about 1/2 dozen PWM to 0 -10 v, but it needed to run off 24 volts for full 0 - 10 range output. Hooked it up to 24 v and poof.
Sometimes you pay your money (throw the dice) and take your chances. Also known as gambling… Better luck in the future with these things.
A dual laser system with fiber optics and prism control / combiner is available and I have also in another post posted a link on the subject, but it cost without the necessary power supply 7000 us dollars. Therefore, I am a little skeptical that we can get this type of laser in the end user market. But, it will not surprise me if the Chinese or him from Russia put up 2 diodes with a prism, why not.
No, no, the laser I’m talking about is serious enough, but just in a completely different price range.
But I will not be surprised if there is or will be some kind of cheap laser diode combiner. The problem is just that for it to work it requires very expensive components and they are definitely not in the Russian or Chinese “30-40Watt” diode lasers for $ 500. That was my point.
Hey Jack, I knew going in to this that the hardware could be shaky, but I didn’t see a whole lot of issues when I did my due diligence.
So like you said, I rolled the dice thinking that my odds were pretty good. It appears I’m the one to lose. But NEJE could have fixed this based on their self proclaimed super customer service and couldn’t be bothered.
Thanks for the thoughts
I purchased a Samsung or LG inductive stove… About $3K. On the 13th month poof. Told me to take a hike. I’ll never buy either of those brands again, it wasn’t just the stove…
You did your due diligence took your chances and crapped out. Generally you come out of it ok. There’s also the education you now have If this is the last thing you’re stung with, thank your lucky stars.
I see a lot of is people running their solid state diodes at 100%. I don’t run anything at 100%. Like your car they just don’t last. My CO2 laser never exceeds 80% and only when I’m cutting. It’s a China Blue. The add claims it’s a 50 watt machine. It’s more like a 45 watt tube as it’s only 880mm long. At 90% it reads just a little over 40 watts on a Mahoney meter.
I have master2s 30w diode quite cutting and gave 3 dots of light while on. I got refund and purchase A30130 it was a bust on day one. waiting on replacement from NEJE I purchased B25424 it works like a charm so well in high dpi I purchase a second one. also I have a 0006 that came with out my first try of purchasing a Master 2s I got a partial refund and kept the laser module it works pretty well but don’t over load the dpi with it. Its discontinued. it draws 18watts and cuts with air assist very well.
laserwurks.com is were you can see the adaptor I made for the little wonderful B25425
That’s a nasty little laser for $500.
