Sehr interessant habe auch den A40640 im Einsatz für mich war dieses Video sehr hilfreich danke für's zeigen. 👍
Great video! Thank you!
Beau travail! 👍
I love your cutting bed! That works all day long, and saves you $200! LOL
Do you take the black focus ring off
In your video when you flip over after 8 Sq cutting the square that does not fall out shows different cutting for horizontal vs vertical path. This indicates Laser dot is not a square but a rectangle. Is this fixable or just bad characteristic of neje diodes. I see exact same thing on my neje laser. It mean more power or second pass to cut just because of laser diode dot shape.
Im debating between this one and xtool however on the NEJE I don't see like an air assist does it come with an air assist or do they have one where you can purchase
if i want to engrave acrylic material ,do i need this method?
Hi, please help me with something. I will work with curved material and rotary. How many mm above does the focal point affect the most?
Brother I have this laser module with air assist and I am having trouble cutting 3mm MDF, did you unscrew laser head?
update it does have an air assist im getting the neje 3s max it should be here in about 14 days im so excited
can this machine cut through thin metal plates
on neje Wiki it says that the laser should be adjusted with a screwdriver. 30mm for accurate engraving and 55mm for thick cutting. should you really do that?
I see your not one to respond back but. Did you ever adjust the lens? Factory it’s screwed fully in.
So I have had this for two months and after the first month 300 hours or so and several cleanings it barely cuts 6mm MDF at 100% power 100mm/m and 7 passes. Please Help
Honestly, visual control variant looks better than the ramp test one.
what's the life span of the laser when being run at full power?
Thanks so much for the video!! There's not much information online about NEJE so it's been difficult to dial mine in. Do you ever use the focus adjustment that's on the laser?
Have you had any luck with the focus adjustment on the laser?
So you never adjusted the lens? The a40640 has a variable focus
My focus is super close to the laser module itself for some reason, is there a way to adjust it down? For me the module has to be basically touching the surface to be focused well.
try changing the position by turning the lens if possible
Hi, thank you for your video. I just ordered mine and still waiting for it. I heard that running at 100% power decrease drastically the laser module performance after 20 hours of use. Did you see any change?
don't worry Neje laser 40w I have more than 4 months and more than 200 hours of cutting (100%)or engraving and no change in performance.
Yes, correct, the my drop
Hi, I'm interested in how you set the laser power, I have the same one, but mine cuts 4mm plywood with one pass only 150mm / m, with two passes 250mm / m that's max? thank you
what type of plywood do you use? I use poplar plywood .Birch and beech plywood are harder and cut slower
@@kukomio I also use 4mm poplar plywood
How to boost speed ?
Hello can you engrave word 5mm x 10mm ? Tks
Where's the link to the file?
1:20. What with the gloves??
Hi, between the Sculpfun S9, the Atomstack X7 and the this Neje with the A40640 laser module which one is the best for cutting, in your opinion?
Your videos are the best ones showing the capabilities of this machines, but also they make me want all of them haha 😂
I haven't tried Sculpfun S9 but NEJE (A40640) and the Atomstack X7 PRO with the right focus point and air assist is very powerful. I personally use more NEJE (A40640)
@@kukomio great, thanks for the answer
Hello kukomio, is it a myth or is it true that if you use the full power of the laser (100%), it will decrease its useful life? I've heard and read many people say that!
It’s true. Try not to exceed 85% for long periods.
Das ist aber nicht Perfekt sind auch total unterschiedliche linien
