I'd rate safety "Extremely scary / 10" for this one, but the free-hand Retina-Remover function puts it squarely in the "Accident from Ebay / 10" range.
These open frame designs are already terrifying, but that cage thing is utterly horrifying... the potential for tipping it over and receiving a kW pulse to the retina is just too high. These manufacturers really need to learn that just because you can doesn't mean you should.
No. People need to learn. Just because they can doesn't mean they should. You sound like the woman suing Mc Donald's for the coffee being too hot. Warn people and let Darwin do the rest.
@@critical_always you know whats hilarious about people mentioning that lawsuit? The coffee was proven to be kept at a much higher temperature than it should have been, so high that it fused that womans private parts together. Also, she only sued for medical bills, and the jury decided to make an example. McDonalds basically ran a smear campaign against her for bringing that lawsuit. People have basically ruined her life because of that, using her as an example of a "frivolous" lawsuit. You need to consider whether its the big uncaring corporation you want to stick up for, or the person with mutilated genitals.
Marco, i want to see how you make your high precision resistors, i think you have almost everything that is needed, amazing projects are on the horizon
For PCB do 3X more pass trought with same speed but only 27% of power there will be no overheating.-.- set freq in to 38-41Khz (copper and brass optimal absorbtion freq) if that still burn you have to shift it in to 51+kHz... When you cut ''trought'' use 2 same vector with HATCH, for example you want 3cm ring.. so set another vector with comon center with weight 3,05cm and that 0,05 gapp fill with HATCH.. that will do the cut.. Agains engrave that by fast pass with every pass rotate the angle by 3degree.. Instead of hard power cut trought and oveheat and melt that material.... i do cut silver and inox like this without overheating.,. trust me if you have any question?? PM me..
The reason for the "warranty void" label on the MAX laser source is meant to keep you from getting nightmares after having seen the inside 👻. As I understand, MAX is on the cheaper side of fiber lasers. Raycus is next and JPT is top of the line of affordable IR fiber. I'd love to see both types being sent to you to take them apart all the way 😁 The EzCad 2 software is nice but I recently switched over to LightBurn (for Galvo) and that is a huge upgrade. The dxf/svg import is much better and has better path closing options. Most of the times, the trace image feature most of the times works great to convert bitmap images into good line art.
My dream is a MOPA laser that's good enough to both ablate copper from copper clad, zap vias and cut stainless stencils. JLC who? Thumbs up for more laser content. Id love to see you mess with fempto pulses and different wavelengths.
Well done... When getting my lazer, one silver screw was rattling inside. Wanted to see where it came from... Without taking my lazer apart. Thank you for the video I think I found where it might have gone. Near wiring harness hook up or the lense from the cylinder.....
20:16 in order to reduce substrate heating there is a hatching technique in which you skip every second line and then cover them with a second pass i wish it was one of the default options
I haven't done fiber splicing for manufacture like this but I'd believe most of that slack is just there so they have something to work with when building the laser and it's just tossed in there and taped down. The little tiny circle of fiber is probably because of an unintentional twist or a short or long fiber with no other choice for slack management. I'm surprised heat sinking is necessary but I guess. Certainly any splice that's not perfect or bend that increases attenuation (usually less than a 3" radius) will burn the fiber or laser quickly.
Perfect tool for a new employee induction - I'ed make it mandatory for all twitter employees "demanding" they be traeted respectfullly for their commie political views :-)
I’ve found aluminum to cut much faster than steel on mine, and on my 50w machine even 5mm deep cuts are possible with enough time. The walls however do significantly taper inwards, so a wide kerf actually improves cutting speed
20:00 : at work we have a KEYENCE laser marker, to mark tool for 5 axis cnc machine and robots. I have tested to engrave pcb, and it works fine (after finding good settings). Thanks for your video.
If you must use it with minimal safety, keep it locked in a room so that someone can't walk in and get unexpectedly blinded. That is a good idea even with proper safety too. It is just one more layer. If you are worried about a fire, just make sure the floor and walls are concrete or some other material that doesn't burn. The idea is that you want stuff that ordinarily never would burn.
Thank you for yet another good review! If you wouldn’t mind, I’m super curious how a unit like this one can remove rust from steel. If you have the time to test it out I would appreciate it!
If you want much better software you can buy light burn, which will probably work with that laser I use it with my fiber laser and it’s fantastic Also a mopa is capable of reducing the NS pulsewidth while a Qswitched will have a fixed pulsewidth. For example, my mopa is adjustable from 5ns pulse up to 200ns pulse Both with be capable of frequency and power adjustments but mopa source usually have a wider range, mine adjusts from I think 10khz to 1500khz
I wouldn't call carbonised PCB substrate "leakage"! It is generally a low resistance and if a power rails goes through it it will burn while the power source is there, even when the substrate is V0.
Very nice review - I've actually been asked to do a review of a similar machine so I think I'll take some pointers from how you've structured your review, as it's the first I've ever done ;-) Also very interesting to see inside the insides of the actual laser source. Regarding cutting metal, some thoughts. Aluminium is actually much faster to cut than steel because it's cleaner - steel produces a lot of burnt rubbish which tends to clog up the cut. For cutting anything thick, it's essential to use either "wobble" or an offset hatch, rather than just trying to use the beam itself moving around the perimeter. Both wobble and offset hatch essentially thicken up the beam, allowing it to reach deeper. The wobble settings are under the "Advance" button under the pen settings. On my 30W laser, I would use a wobble diameter of 0.5mm and a spacing of 0.03mm to cut 1mm aluminium, with a speed of 1000mm/s and power 90%. Your 20W won't be as fast, but I'm confident it will still cut in a reasonable time.
A triple beam focus system that's adjustable is really useful if trying to make a lens hotswap setup. That being said it would be more useful if they're 2 different color beams to easily distinguish between the 2 distances but better than nothing even all being the same color.
Marco, try Meerk40t - open-source software for galvos with JCZ controllers (which seems to be this one too). As far as i know no class 4 laser product can be imported as private person in Germany... what do you think, if i back it on kickstarter will i receive it at the end?
Hey Marco, my fiber laser here at work has the same software, could you share that file for the color engraving? I was gonna go thru doing all the pen colors with different settings but i never get the time.
What a great video. So much useful info. I’d use one if these in my shop every day! If you decide to pass this prototype along to another maker, I’d gladly pay shipping to the US! 😁
On Mata Nui, I learned that no one stood alone. On Metru Nui, I learned that actions, not fate, defined a hero. On Voya Nui, I learned what it means to be determined, to face your fears. On Mahri Nui, I learned what sacrifice truly means. On Karda Nui, I learned to never give up, even in the darkest hour. On Bara Magna, I learned that anyone, anywhere, can be a hero. United in Duty, Bound in Destiny. That is the way of the Bionicle.
This would be really neat if it had more safety features. The kickstarter advertises them as "Stop switch". That's it. That's the only advertised safety feature.
The third dot was just to ressemble your channel icon. A late idea hurriedly implemented by the community manager right before closing up your shipment. ☝️😅
These seem so ridiculously unsafe to me. Not only because I've heard that a lot of these glasses dont work, but because they are fully unenclosed and some metal at the wrong angle means you are permanently blind.
It uses IR. Most polycarbonate plastics like Lexan for instance, absorb/block nearly all IR light. Making safe IR goggles or simply building a shield wall would be trivial.
What about heating the aluminium while the laser is trying to make a cut? I mean in that way the aluminium will not be able to dissipate enough thermal energy to neutralize the laser.
Sooooo.... What are the alternatives here in Germany for a small one-man-shop that wants to add to a portal-cnc-mill? I do really like the concept of this one as my main scenario would be metal and (now preferably darker) wood. The rotary axis is an absolute must! Love it 😀 I also thought about a laser-head for the portal-mill owever there are not so many for a beginning shop.
Just an observation about dog tags. Putting your address or phone number on them is an invitation to have your pet stolen and ransomed. Maybe a better thing to do is simply write on there that your pet has an RF chip fitted. Then, the person finding your pet knows to simply take it to a vet for scanning. This makes pet-napping a much less lucrative occupation, since the thief has to take the animal to a third party who holds the relevant data. It's a pity the world works like this, but here we are... I don't have to worry about these things because my dog is a Border Collie. He's an excellent judge of human character, and can write his own name and address for them if he decides to trust them.
Oooh. How about a demo cleaning rust off sheet metal or some dried on tarry goop off of glassware like a test tube or slide? Probably an unreasonable request on the machine and a lot of work for your exhaust system
What do you suppose is the narrowest line you could get on anything metal? Finely engraved radial markings and a USB microscope make for a pretty good, cheap, indexing solution.
Holy shit, this is terrifying. I'd love to to have one but there is no way I'd turn it on without proper goggles. Hopefully the price keeps the idiots away before the government bans them.
This whole video was worth it for the custom ripple clamp. Thank you for the first audible chuckle of my day.

Lasers reflect off of things? Into _my_ eyes? No, that couldn't possibly happen, I've got my safety squints on.
Yes it's quite spooky, perfect for Halloween season
Don't ever watch a video of laser rust removal or else you might have an aneurysm.
No. People need to learn. Just because they can doesn't mean they should.

I have no need for this product. On the other hand, my need for Marco Reps videos is INSATIABLE.
You can put thermal paper under gogles to check if some light went. I would burn or blacken
Ah yes, thermal paper, like our retinas are made of
"Should we look at a femto-second laser someday? Since I already have the goggles." Sure. Go for it. If you can get one.

Marco on fire! Einfach geil, wie viel du gerade rausballerst!
Fantastic video as always! I always wanted to see inside one of these fiber lasers!
2 uploads in 2 day! Praise be!

very important and educational video I just understood how ComMarker works
I’m very impressed with the capabilities but slightly concerned I’ll discover it has a eye-surgery section at the back of the manual.
that fluorescence looks just like the europium doped glass that's used in the borosilicate industry
Your humor is super good!

Hey, I just learned about F theta lenses and calibration in my masters class!
Love the up close and detailed shots! Amazing what these can do for the price range.
Not sure what the expense is, but what an amazing tool. I liked the clamp. Made me laugh out loud.
~3000€
Wow, this seems exceedingly unsafe in basically every imaginable way
if this looks too scary for you to use, simply don't. These are definitely meant for people who know what theyre doing.
Still not dangerous enough for Marco Reps though, nothing is
I like it!
Perfect tool for a new employee induction - I'ed make it mandatory for all twitter employees "demanding" they be traeted respectfullly for their commie political views :-)
Just wear safety glasses. I have a 50w fiber laser and there is nothing particularly dangerous about it if you wear your glasses

the 3rd beam is for cylindrical items on the rotary devices.
But how many ppms does it have? And does it have more digits than a clock?
Doesn't matter, you had me at laser.
That's the thing with overkill: you can never have too much overkill
I'm sorry did you say "handholding" a fiber laser? Sounds unbelievably fun
Wait till you search for "handheld laser rust removal", then it gets really fun ;-)
@@imajeenyus42 yeah, seen those but the price is beyond what most can afford for home use. I just wanna burn things lol
I found a dog tag exactly like that one engraved in the same manner on a beach near Wangerooge this summer, someone is already on it!
I'm pretty sure that the 3 laser points are there because the predators had 3 laser points too on their shoulder cannon.
I have waited for one of these to fall inside my budget for quite some time. I am glad to see it!
Spend your time engraving rings, great video
If you want much better software you can buy light burn, which will probably work with that laser

Also a mopa is capable of reducing the NS pulsewidth while a Qswitched will have a fixed pulsewidth. For example, my mopa is adjustable from 5ns pulse up to 200ns pulse

I'm sure you're aware of breaking taps channel but he does a lot of science with one of these cheap little fiber lasers
Love your teardown videos. And the jokes in the videos are sure hilarious. Thanks
I wonder if the complete pcb etching would have been cleaner if it was performed in multiple lower power passes.
Further exploration of the comments reveals someone else explaining how to do this. I feel validated.

Very cool! I want one. I have no need for it. But, I want one. Once again love the humor. 😂
Woulda been cool to see a piece of paper under those goggles when you engraved them (edit: sorry ignore that - just saw the tissue clip!)
A black piece of electrical tape maybe
Awesome review; it really makes me want one :) Looking forward to more content from you 🙏🏻
The one ring to rule them all.

Nice video
Do you have a link for the safety googles
Looks like there is two focal length guide lasers and one from the galvo for alignment.
What a great video. So much useful info. I’d use one if these in my shop every day! If you decide to pass this prototype along to another maker, I’d gladly pay shipping to the US! 😁

Ripple clamp genius!
thank you for the education. so interesting,

Ripple clamp... awesome.
4:50 - three laser points to account for tilted surfaces?
I really wanted to see you burn some paint off your drywall when you picked up the laser module or handheld use.
V-cutting alumina was impressive for some reason
The label on the laser says MFPT-20M and that is in fact a MOPA laser. Or it's suppose to be anyway.
I love your sense of humour! What goggles would you recommend?
Einfach immer herrlich deine Videos. :)
Need to give Lightburn a try ;)
Hey, thanks for the video. Can you cut silicon wafers with this thing (like breaking taps)?
Danke!
that ripple clamp ... can we get a tutorial on that ? and how/when to use?
Nice Corn Maker machine

+1 for the ripple clamp!
The B3 10W version of this machine, plus several other products they produce, are currently available on Amazon.
Looks great for prototype PCB along with other things.
What's the price?
Another video?! Is it christmas already?!
15:49 can you make it print full color images in oxide layer?
Do you plan a test of the LumenPNP? That would right fit into the electronic manufacturing manufacture :)
Do a dental xray machine for PCB trace routing diagnostics on multilayer boards!
What about heating the aluminium while the laser is trying to make a cut? I mean in that way the aluminium will not be able to dissipate enough thermal energy to neutralize the laser.
