Hi, I am using a Vevor 4040 table running Lightburn software. I want to upgrade my laser to be able to cleanly cut through 1/8" to 1/4" wood. Probably Bass, Poplar, ply woods. I am looking for recommendations for a high quality laser with air assist. Probably around 80 to 100watts?
Let me know your thoughts.
Thanks,

If you are happy with the brand you already have then buy it again, just with min. 60 Watt, preferably 80 Watt. 100+ Watt is not needed for the desired task. I personally can do what you describe with my 60Watt OMT, it is now almost 5 years old and has done the job to my complete satisfaction plus it cost much less than some of the other brands.
Vevor puts their label on everything from automotive equipment, microscopes, sewing machines, engine exhaust headers, tires/wheels and other things including forestry supplies…
Size of your table doesn’t tell us anything about what kind of laser you have.
Could be co2, led or even a fiber…
Having your profile updated to include your machine, helps us help you.
Generally speaking, I think @bernd.dk is correct along the lines of his suggestions.
I’ve actually cut 1/4" (~8mm) plywood with my 43W tube.
More power in a co2 is related to how thick you want to cut. If you cut 8mm once every year you can run your equipment harder as it’s a short operation. If all you do is cut 8mm ply, then an 80W or greater would be more effective for you.
Usually when you have higher, you loose at the low power end trying to engrave. I’m on my third tube and I just do whatever I want, usually engraving and cutting.
My current tube is 50W and works fine for what I do. Even my 43W would cut 10mm acrylic.
This is my 43W machine, years ago, cutting 5mm sub flooring at 11mm/s@45%. Besides the head, the air assist and fan are stock, lid fully open.
Sub flooring is very tough and more difficult to cut than most same thickness plywood I’ve used. You can do a pretty good job with less power than you would normally think when things are setup properly.. just part of the learning curve.
I cut 10mm bamboo wood (tough material to cut) with a 40w diode laser and focus at the top surface. If you are going to cut or etch clear materials, go with a CO2 machine. Otherwise, the Sculpfin 70w is capable of some amazing detail too.
Hi Jack,
I was asking this info for my brother who owns this table. He said he has been over it and there is no identifying stickers of names or numbers anywhere.
he sent me pictures of the control PCB.
Maybe you can identify it and if it can run a 40W laser. I think he is looking at an LED laser from Laser Tree.
Thanks,
Kevin
If you upgrade and need more current, your motherboard is unlikely to be able to supply this extra current.
You can add an extra power supply for the laser itself, the pwm from the control board should be fine.
I don’t recognize the board, it has a mechanical relay, which most of these for lasers do not, so I’d think it was for a 3 axes cnc machine. But these type of machines are not what I generally work with, so someone could possibly identify it.
He’ll have to find out what kind of board it is to really find out anything. It appears to be compatible with a 48V supply, higher than most lasers in the hobby world use.
Mine runs off 24V, but they claim it can work with 36V, but don’t recommend it.
Thanks Jack. Have to see if he wants to run a secondary Laser Supply for 24volts
