EVERYTHING You NEED to Know About Galvo Lasers in 2022

[@bskull3232]

Laser equipment developer here (semiconductor annealing and stress mitigation). I'd like to chime in for a few things. Firstly, MOPA is not just for color engraving. MOPA has a more precisely controlled energy release (tons of energy is already stored in the fiber before the seed source flashes), so it can achieve a narrower pulse with a higher peak, aka it gives the material less time to transfer heat elsewhere, meaning watt for watt, it can reach a higher peak temperature, thus having higher ablating ability. On the other spectrum, by having a higher pulse rate and a lower pump power, it can deliver very gentle energy not to ablate materials but only mildly heat it, that's our beloved color engraving. Both are incredibly valuable for material processing. Depending on your needs, a good MOPA laser can sometimes even rival a picosecond laser (which is a LOT more expensive). Secondly, due to the fiber gets pumped before the seed flashes, it is possible to precisely determine and predict timings, and by the magic of compensation (called simmer), it is possible to achieve even pulse energy (traditional Q-switched fiber lasers have significantly weaker initial few pulses, while first pulse uniformity for MOPA can be less than 10%). This makes start strokes and end strokes much more consistent compared with other parts of the work piece. As for pulse energy, it is actually not that important compared with peak power. With similar pulse energy, a 0.8mJ JPT M7 is much weaker than a 1.1mJ JPT M8, even the M8 is only rated 20W while the M7 being 30W. The trick here is with peak power. M7 outputs 16kW peak power, while M8 outputs 55kW. Even without a beam expander, M8 is able to machine glass, traditionally only possible with picosecond lasers or UV lasers. Of course, despite having a higher peak power, it also comes with higher pulse energy, so more burning and rougher edges compared with a proper picosecond or UV laser, but hey, we are talking a significantly cheaper and more versatile package. Also at 55kW, you can laser ablate thick copper and even silver, which were again, not likely to happen with other fiber lasers. What sucks is that JPT M8 is not available from most engraver manufacturers, you have to buy the laser directly from JPT and DIY the engraver. That being said, it is a nice little tool (literally little, not much larger than a bluetooth boombox), with no output fiber (it mounts directly to the galvo like UV lasers, JPT even sells units with galvo and JCZ card integrated with only a USB-C interface and 24V supply exposed outside), and the entire solution can be picked up with two fingers. If you ask me, my personal favorite currently is M8 and Lark (JPT's UV laser, I use for ceramic scribing and polyimide cutting). I might be a bit biased, but I really have good experience with JPT. Raycus is known for welding lasers, and Max, well, is known for being cheap. Unless you are into the IPG or SPI price range, the best bet would be JPT (and their stuff are better than SPI in many aspects, still behind IPG though). Disclaimer: I don't work for JPT or any brands mentioned above. I teach at a local polytechnic university, and I tinker with laser stuff for some side incomes. TLDR: check out JPT M8, it may change your views on fiber lasers. It can "cut into" the UV laser market in many applications, while still being cheaper and more versatile.

BEST “INTRO” video I have found yet!!! Been researching fiber lasers for a couple months now. Looking at the QS-50 Cloudray Pro but I was stuck on what limitations the RAYCUS source had being lower freq limited. Really difficult to find that info until I got to this video. Extremely helpful. My use case will be primarily marking type 3 anodized aluminum receivers for SBR compliance (low volume). Again, thanks a lot for what you guys provide. Now I just got to make my mind up!!

[@LaserEverything]

Thank you! Glad you enjoyed and got value out of it! We've also had some hands on time with that model (posted a video back in December on it. Gotta say it's been good so far. The frequency limit isn't always a huge factor, really depends on each particular use case. If you're primarily doing FFL and similar engravings for depth, challenge coins and stuff, and don't have need for getting crazy colors and stuff, just basic marks at varying depths, maybe some textured layers, totally can handle that. If you need or want to do more, then its a bigger conversation and debate hehe. Keep rockin!

[@walimo6810]

IMHO a discussion on 3D galvos is needed in 2022. Which I guess will also increase the attractiveness of EZ CAD 3...

[@LaserEverything]

Personally I think they're pretty limiting when you can take advantage of the deeper field on larger lenses for most curves. Unless you have a specific use case for it I don't really think they're necessary and stop you from doing basic things like swapping lenses depending on the unit

[@abc123horse]

Hello Alex. Exemplary content. I have been searching Laser Everything videos for more information on laser cutting. There is much content addressing engraving. I would like to be directed to sources for reviews and demonstrations for lasers used for sterling silver and gold cut-outs for pendants. I would like to learn about cutting out blanks or intricate cuts piercing metal sheet up to 8 ga. or 1/8”. Most material I would work with would be 14 or 18 ga. Thank you for your instruction.

[@LaserEverything]

Awesome, thank you! Glad you're getting value out of it. For cutting metals like you described at that gauge you really need a fiber laser cutting machine which is quite different from the galvo machines we talk about in this episode. This video will give you more of an idea of what you're looking at: kzbin.info/www/bejne/Zneafoiaj7CHr5Y They're significantly more expensive but cutting 3mm silver on a galvo laser like the ones in this video would take hours per piece.

OK, stupid question time. So I bought a 50 watt fiber Raycus machine. Just uncrated it today after sitting in the garage for four days (darn inconvenient of me to have a heart attack on Memorial Day), and although I would like to be the trusting type, scars on my butt have taught me to be not so blindly trusting. There are virtually no markings on the unit indicating a model number, or anything to tell me exactly what I got. This got kind of complicated because the company I purchased from was having trouble getting the laser out of China, and I discovered that they had an identical one in their USA warehouse. So I got them to ship that to me instead. But this one came without the rotary attachment, which it should have. No telling if the controller board is in the box, but the connector is where it is supposed to be. So that got me thinking, HOW do I know I actually got a 50 watt machine? There is a label across one of the screws on the case, which plainly states I void the warranty if that label is damaged, so I presume that screw is necessary in order to get inside the box to take a look around. Paranoid? Yeah, a bit. But even a mistake and not anything intentional would still leave me holding the bag. So any suggestions? BTW, I signed up on your Discord channel, but it is DEMANDING my phone number. Uh, thanks, but no thanks.

[@LaserEverything]

You'll have to physically open the case and inspect the parts. There's no work around. If you don't want to sign up for Discord we have a link to our facebook group in the video description as well.

Wow, so much info. Do you think there might be a chart we could use for a reference? My head is spinning lol

[@LaserEverything]

I'll definitely look into that.

[@rewilfert]

Question about controlling these galvo lasers. I understand you need a separate computer to run the EZCAD or LightBurn software. If you had multiple galvo lasers, all the same, or a mixture of CO2, fiber and UV, would you need a computer dedicated to each laser or can one computer run multiple lasers at the same time?

[@LaserEverything]

If running ezcad each computer can only run one instance at a time. You can control all of those units from one computer, just not at the same time, so you'd need how ever many computers as you'd have lasers running at once.

[@rewilfert]

I understand that MOPA gets you more versatility due to the wider frequency range. When you compare a non-MOPA with a MOPA machine, are there situations where the non-MOPA machine can do more than the MOPA? Or does the MOPA machine simply build on the capabilities of the non-MOPA? In other words, is the MOPA machine in any way less capable than a non-MOPA machine?

[@LaserEverything]

Nope, MOPA is fiber laser + pulse duration settings.

[@michaelhorton2133]

I had the same thought! Glad to get an answer

[@krisknowlton5935]

You almost had me convinced to cancel my order for a Raycus and upgrade it to a JPT. But for $1400.00 I don't think it would be worth it for me since I am retired and will be just messing around with this just to keep the two cells of grey matter I have left a little bit of a workout. From what I've seen in the videos of the Raycus machines it should do what I want. As always you have good content.

Do any Fiber lasers run on MAC OS? Great content and I am scrubbing through it all and recommended brands and packages for a 50w, and all I see is "Windows Support only" for the machine? Before anyone gives me input on Windows versus Apple...I run an app development company and full hardware manufacturing business around Apple and the iPhone and iPad...and there is not a single Windows computer in our space. So just curious on MAC support for these, as I see Lightburn supports it but the machines all say Windows only. Appreciate the feedback.

[@korbx]

Hi Alex! Awesome video, immensely informative. Quick question: can a standard fiber laser (say 30W 110mm) achieve a 3D engraving without a z axis? Does the depth of field parameter you mentioned affect that?

[@LaserEverything]

We call it 2.5D engraving which uses heightmaps. You can do it with an Ezcad 3 board with that extra feature unlocked (paid) or on an Ezcad 2 board with LightBurn (free). It does not require a 3D lens or motorized z-axis and people are doing some really cool stuff with it. I have plans to do a video on it but other stuff has just been in the way. The deeper depth of field will certainly help you remain in focus for a deeper "3D" engraving but you also have to consider the laser behaves weaker on larger lenses so there's always a trade off.

This was helpful. I'm an old guy looking for something to do. I don't intend to make any money with these but I want to get a general purpose (whatever that ends up being) laser for complimenting my wood CNC.

I want to go with something like 50W with capability to deeply engrave when necesarry, but also like coloring feature for stainless and plastics. Thank you.

[@LaserEverything]

Not really sure what you mean by slower or faster. Typically for all intents and purposes they operate at the same speeds. Maybe some MOPA specific settings require slower speeds to accomplish but the machines in general are capable of the same top speeds and I can't think of anything off the top of my head a q-switched laser can do that a MOPA can not.

Autofocus makes the machine very hard to use when you're trying to do anything out of focus on purpose, which happens more often than you'd think, would avoid. Motorized z-axis is a different story.

The lenses are so cheap compared to the machine at $70 - $100/pc if you get them from the right place. We have some links in the buying guide (link in the description). I recommend getting as many as you can afford across the widest range possible. Something really small for super deep engravings, something mid range for typical work and something larger for coating removal and large area projects at the bare minimum.

[@LaserEverything]

It's absolutely possible but there are a few challenges. First the dot size. The dot size on CO2 galvo, like gantry machines, is rather large. That can make it pretty difficult to get good detail out of small marking areas. Still there are ways to better that like by using a small lens or by upgrading your galvo head and beam expander. That said the CO2 galvo follows all of the same rules and principles we establish in our photo engraving guide. It's an excellent video and I highly recommend it as we cover Ezcad AND LightBurn, you can find more info here: kzbin.info/www/bejne/e3OXYYZsdqqJrac

Thank you for a great and very informative video! How would I find my laser dot size pre-expander on my Galvo CO2?

[@LaserEverything]

I'd make a .0001 diameter dot in ezcad, center it in your workspace and then mark it. The diameter of the digital dot will be way smaller than the actual physical dot size so whatever you end up with when you mark that dot is going to give you a good idea of the dot size. Then you just have to measure the diameter of your marked dot. Just make absolutely sure your laser is focused otherwise it will skew your dot size larger than the actual minimum.

[@LaserEverything]

You won't be doing things like full wrap arounds without a rotary but if you're okay with that I'd really recommend at looking at something like a CO2 galvo machine. 30w+ should do fine. I really like my Coherent from Mactron - there's a link in the description. Does a great job at burning away the powdercoat without marking the metal underneath which leaves you with that beautiful brushed metal finish and works great regardless of the powder coat color.

[@artantme]

Thank you for the very detailed review! Do you know what manufacturer i should choose to be able to etch copper (like pcbs or brass jewelry) I have just tried using a YHFM-30 laser with 110x110 lens which etched steel and aluminum no problem, but did nothing to copper at all. Like nothing :(

[@pacifictexturingthaliamadd8660]

Forgive my ignorance, but you said with the Raycus we would be stuck with lower frequencies. What does that entail? It wont be able to burn as hot as a higher frequency fiber lasers? Or its slower to achieve the same depth kind of thing? I am looking to purchase one asap but intend to engrave depth into metal (as I have been with my trotec lasers) from anywhere of .003 to .010 and up. The Raycus can do this just slower? Am I getting that right?

[@LaserEverything]

Higher frequencies allow more flexibility in non-ablation marking. It basically spreads the power out over a greater number of pulses so that you are hitting your material so hard. Great for non-standard materials like plastics and organics. If your focus is taking chunks out of metal it's not so much of an issue.

Great video! Curious if there is anything people do when using portable lasers to ensure that they put safety glasses on before firing up the laser? Hang eye protection over the on button? Hang a sign in a spot that you would pretty much have to move it to use the laser? I ask because I come from a safety culture and just knowing that you have to wear eye protection or having signs on every wall doesn't always stop people from forgetting PPE. Signs on the wall eventually fade into non-existance after you have seen them every day for weeks/months on end. After hearing what you said about class IV lasers, forgetting to use my eye protection is something I would not want to forget.

[@LaserEverything]

This is a really good question Larry, I keep all of my goggles on the wall and look at them every time before I fire up the laser but it's not fool proof and I've certainly forgotten before.

[@efeocampo]

Not only eyes safety, Larry: I am highly concerned with the fumes of the evaporated materials... They could be toxic !

[@LaserEverything]

We have a very good exhaust system that keeps fumes and debris out of our lungs :)

Any opinions about gainlaser UV laser?

[@MrLosiu1122]

Hi I'm currently looking at muse Galvo 50w. They have 3d camera on them for easy use. I really like that idea,. It is it worth extra money? I'm looking to make part marking barcodes, serials numbers etc. Will camera help me with some curve surface or that just waste of money? Thanks.

[@LaserEverything]

I don't know a lot about their camera systems but muse uses proprietary software and hardware so there won't be a ton of help from the community outside of other muse owners, just an fyi.

hey thanks fir all of the helpful info boss! about safety: im planning to use window tinted film for my laser enclosure CO2 [diy] and fiiber. from your experience, do you feel will that protect eyes from laser? btw, i have glasses too. thanks again and keep up the great work!

[@LaserEverything]

Tint alone is not enough to protect from the fiber. The fiber laser operates in the IR - Infrared spectrum of light. What may be opaque for visible light can still let IR radiation through. Best to use film or acrylic that has been specially treated and rated to protect against 1064nm wavelength light. You can check some examples out at: noirlaser.com/lasershield-windows/

What are your thoughts about the ComMarker B4 - new 20W fiber....but with a Max source inside?

[@frankypete2677]

Thank you for this awesome video !! I would like to build a galvo laser for a wide range of applications with a movable x,y,z axies. Would you recommend to buy and unmount a portable unit in this case or is there a cheaper way to buy just the laser without the stand? I am unsure if I should go 30w or 50w, I would like to be flexible in terms of detail/power (for wood, metal and fabrics in different sizes). Can you recommend one over the other in this case?

[@LaserEverything]

We've not looked into that type of DIY build before, but first thing to consider might be more about your materials first and the expectations you have on the effectiveness the laser will have. If you intend to go with a fiber source, it will not have a great affect on wood (and in some cases, cloth), co2 galvo will not have great affect on engraving into metal. You may need to decide which materials are most important to you and pick a source type based on that. If you'd like to get some feedback on this, head to the discord link in the description and you can make a forum post in the Misc area about your build. Me, Kyle, and the community and mods can give feedback and help and follow your progress that way.

Can anyone tell me if these laser engravers engrave on granite and porcelain tiles? Do they do a good job with photos? Specifically fiber lasers?

[@LaserEverything]

Fiber will do a decent job on those materials as long as they are dark. Lighter iterations will cause more issues or won't work at all. You need a large amount of that laser energy absorbed rather than reflected to get results. Fibers are great at photos on the right materials.

[@steinbierz]

If you don't really care about color but would like the other benefits you mention of a MOPA are you still faced with the same learning curve...or is the curve just to master color? Thanks.

[@LaserEverything]

There is still a learning curve. You have to contend with pulse width on most Mopa lasers, which is good and gives you more control over power, so if you're doing deep engraving or cutting, you can tune more aggressive parameters that still get good detail, but is another layer of tuning. You can also keep it basic, set the pulse width to 200, and start with that as a learning point.

Is ezcad board an alternative to ruida controller? Do you have experience with ruida controllers

[@LaserEverything]

It is not. Ezcad controllers are specifically for galvo operated machines whereas Ruida controllers are for gantry operated machines.

[@layneyost7393]

Great video. I have a Full Spectrum Laser CO2 machine. I went with that company because I do everything on a Mac. They have a program on the laser called retina Engrave 3 and the Mac interfaces with it. Also the Mac OS Affinity Design program is fantastic. Does anyone make a Mac interfaced fiber CO2 machine that you're aware of? Be nice to have more speed then a gantry can provide. Thanks

[@LaserEverything]

Most galvo lasers these days are supported by LightBurn which is MacOS compatible. We cover everything you need to know about LightBurn for Galvo in our crash course series here: kzbin.info/aero/PLoBR3k35202Yjc1yMfPZsY8EDh_pmcaa2 While most of this series takes place in a Windows environment it's virtually identical for MacOS. We also recently got a Macbook Pro so we could do some MacOS content for our viewers as well and we'll start to see that content next year.

Hi, what are your thoughts on FSL Galvo 5W UV Laser? Does the specs justify the price tag?

[@LaserEverything]

I tell everyone I can to avoid FSL - proprietary parts, proprietary software, you have to get support and repairs from them and they're hard to find out in the wild so finding other people who use them had have the same struggles can be a challenge. I'd always recommend going with someone else that uses off the shelf parts so you can be in control of taking care of your machine.

[@MortgageEasy]

Great video! I am new to laser and want to use for firearms. What and where would you recommend I buy my fiber laser for under $10k? I want a good one.

[@LaserEverything]

The 50w Mactron machines (or their 60w M7 systems if you have the cash) would be perfect for that use. Check out the link to their store in the description. They've been my #1 recommendation for two years now.

Hello Alex, need some help. I have a customer with Victorinox knives and want to engrave the plastic handles. I had 100% success with the black but none with white and red. Is it possible to engrave on these 2 colors or the color absorbs energy? I have 50w JPT fiber laser. I know that this is a UV job, but i do not have one. Thanks

[@LaserEverything]

Those colors on fiber are mostly going to *reflect* the 1064nm beam. Try on a CO2 or UV laser instead if you have one, you'll have much more success.
