First of all, thanks for the excellent demonstration. If it is not too much, it would be possible for you to show the settings in the software you use to cut these 3 elements: 10mm plywood; MDF 5mm and Acrylic 5mm. Thanks
To increase the efficiency of the cut, would be great if a 3rd axis is added, so after one pass, your height is adjusted to have the focal point 1 or 2 mm lowered so you are always going for the max of the laser.... this probably will make the 10mm board cut in 3 cycles. I tested it by manually lifting the MDF thou is very tricky to maintain perfect alignment... would be easier to have a 3rd axis, and do one pass, then adjust height and go for the next pass
Fantastic. What I already saw on YT was that they needed 5-7or even more passes to cut 6mm plywood at 70% and it even burned a bit, air assist should help tremendously. I will copy your idea of the box and the syringe to get air (1bar is enough as I see it) I got some silent compressor also will buy 10cm tube and an in tube fan to take out smoke to a window. and of course the bad of nails idea is just great :-))))
@@modellbaukalender Hi yeah I made it all and it worked b ut it was still very slow (and because of that it was a bit unreliable too)... So I bit the bullet and invested into a CO2 60x40cm chinese laser and I did not regret it at all. 6X faster all I can say. izt is a world different. I can just offer it to anyone. These Diode Lasers are good to learn laser cutting also good for paper and engraving (bit evn slow for that) but if you really seriously want to cut than CO2is the way to go....
For business i think it's not really profitable. It is to slow and too unpredictable. But if you have time and not every cut must be 100% perfect, it is an cheap option.
Is this NUBM44 445nm Laser Diode something special stronger than usual??? I ordered an Atomstack A5Pro from Bangood with new spot lens they say it cuts better with the new optics. I would make a box for it with fume extraction and also air assist. I would cut 2-4mm plywood and balsa and foam...do you think it is realistic???
The description looks really good. I think 4mm plywood should be possible, but i can't say it for sure. Maybe you can tell us more after first test....
@@modellbaukalender My mistake, its the reference for a 7.5w module from Neje. I prefer the idea of a dyi module but It's hard to find a nubm44, so I ordered this one from sculpfun, ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ymS3sai4xxE.html. Its a 5.5w diode. But the focal would be "specific" to be longer than usual. What do you think about it?
It is very impresive. Are there any chance to cut hardwood (for example, 3mm of mahogany, rosewood, maple, ebony...) with a NUBM44 diode laser? What about the new 40w diode laser (Neje)? Thank you for your instructable video!
@@modellbaukalender My Neje A40640 (40w input, 10w output) Can do 12mm oak in 2-4 passes. I cut 23mm pine in 8 passes. It will NOT touch walnut, or cherry lol. They're just too dense I think.
Can you put exact model of your laser module, I tried to locate one for my cutter, but not clear which model I should buy,..., thanks a lot in advance!
What Laser module can you buy to easily upgrade with the NUBM44 laser diode? I know nothing about electronics, but I want to start in laser cutting, and there is no module it seems that can cut through mdf just like in your video for a good price.
I don't understand... Most videos or articles out there say you absolutely can't cut properly with diode laser... How can you cut MDF so properly with such a low power laser?
I haven't a Laser Power Detector, but it should be about 6W. Fan i have have changed, look at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-19Vr2B-J19Q.html
hi....which type of NUBM44 Laser Diode use? 5w 7w 10w ecc ecc? which type of 5a constant current driver ?,on site there are various types.......which type of lens....one lens or whit three element?-----tks
My laser housing is 30mmx30mm, here I use a double ball bearing fan with 30mmx30mm, see description. For the laser driver I use a server fan with 40mmx40mm
Sorry for my question . I need a powerfull diode has yours or bigger if possible. The air assist give more power do the laser and is your invention ? I can´t find any diode with this air assist systeam ! Have you any link, if possible from Ebay to buy one? Thanks for the excellent video.
Hello, the air assistance only helps to blow away the smoke and ash so the laser is not obstructed... if you need more power maybe you look for fiber or co2 laser
Look in the datasheet ;) I can't say it, the max power of this diode is about 7w. At the moment I use it with a little lower Power, i think it would be about 6W.
Doea it cut 6mm plywood in two passes??? I don't believe my eyes... this is a 7W diode laser no??? Is there something very special in this laserhead???? Or does the air assist helps that much...???
comparing the cnc I have, your 3mm mdf machine makes 3 passes 300mm / min, a router makes 1 pass 500mm / min. How much would a 40w machine do? like Neje
A 40w laser works much faster than a 6W laser, of course. But the standard k40 lasers are relatively limited in size. I can easily convert this LED laser to 2000mmx2000mm and more.
@@modellbaukalender man this is awesome but i dont have a clue how to assemble this from parts. :) i cant wait to see more cutting from you with this. whats the total cost to make this?
The secret to cutting on large thicknesses is the jet of air concentrated on the cutting point, this prevents the creation of carbonization, which would prevent cutting in depth. In any machine with 7W laser it is enough to implement an air jet
Hello, I bought a laser for my wife's work which is 30w 7.5w external apply. but it can not cut wood more than 3 mm and this is a problem for their work and it k blackens it all. while searching i saw your video and bond that it was great. Could you tell me what air machine I need to help it cut me like yours? I saw the video you made of the air machine but unfortunately I do not have such knowledge to make. only one ready I can buy. Thank you very much.
