What laser module came with the Neje and what module are you comparing to on the Atomstack side? Depending on the model there may not necessarily be that much difference.
And keep in mind any of these differences for any diode laser system is going to be relatively small. We’re talking at the max a 2x difference in cutting power. If that’s what you’re looking for then worth exploring but I wouldn’t recommend just switching expecting a dramatic difference.
There are a number of topics exploring the various laser options in depth I suggest you do a search for. You can followup if there’s something not addressed there.
As for pricing of your unit I couldn’t say. If this is brand new wouldn’t returning it be an option?
I wish the manufacturers would really cut it out with the misleading numbers. I thought the industry had turned the corner on that but I guess not. The 30W and 50W numbers are input power numbers. The real focus needs to be on the output power. The Neje unit is now generally referred to as a 5.5W laser module. The one in the Atomstack is in the 10W range. It’s not directly comparable because they’re claiming these numbers based on the use of 2 laser diodes.
So you’re likely to get realistically not quite a 2x increase in cutting power. There are a bunch of other factors at play. This will be enough likely to get through your 3mm ply but it won’t necessarily be easy depending on the quality of the material. Solid hardwood would be far more predictable.
So the Atomstack laser module will certainly be faster, but necessarily “fast”. This is going to depend on your needs and definition of fast. Take a look at some other posts to see what people are seeing.
One suggestion that you might not have considered is that you’re perfectly capable of upgrading your laser module without replacing the entire laser platform. Neje, Atomstack, and others all sell replacement modules. Neje themselves were one of if not the first common brands to have a dual diode module.
Oooo thank you for the tip bc it is what i’m doing
Most of the time I’m doing this
Engrave aluminum plate
Cuting haevy sand paper
Always at 100% I’m just changing the speed
What power do you recommend max I can use?
If the 30 watt is 7.5 watts, there is no way the 40 is 15 watts. A 33% increase in input power will only give, at most a 33% increase in output power.
If the 30 model is 7.5 watts the max a 40 watt model (.33% more power) could do is an increase of 2.475 watts (7.5 *.33) so there’s a maximum increase to 9.975 watts for the 40 model. If it’s the ‘dual led’ version, they now have added more loss in the conversion with a beam splitter.
I’ve read a lot about what the output power of these devices. I read in the engineering journals that you get about 10% out for a given input power. Yet I read where they typically advertise a 20% or more conversion factor.
I have a 30 watt Neje, it’s a good laser, but I doubt I’m getting much over 3 watts.
