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.

[@AchOwed]

Thank you for your thoughtful post. I was interested in getting a JPT M8 MOPA laser, but I could not confirm that it marks, etches and engraves and colors stainless steel as well as the M7. In your experience, does the M8 do everything that the M7 can do? Thank you in advance.

[@bskull3232]

@@AchOwed From paper specs, yes. But I've yet to spend time tweaking M8 to do color engraving. My line of duty involves using laser to cut holes and to bond materials, not to make oxidation layers, so sorry, I can't tell for sure for now,

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!

[@ostryFAN]

on galvo I will get a similar effect as on the diode when marking photo on ceramic tile?

[@Burbsi]

if you don't own/operate a laser yet: A galvo is a speedy engraver while a gantry is a good cutter. if your main work is to cut puzzle tiles, you need a gantry because they cut straight down @ 90° (galvos cut at varying angles, soley dependig how far the cut is from the centerpoint of the laser ) - if you plan on engraving a ton then it does make sense to invest in a galvo that will save you hours of time because it's moving the laser so much faster.

[@LaserEverything]

Yes indeed so many people get these intending to cut with them only to discover they really aren't made for that kind of work. Good pro tip.

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.

So just curious on MAC support for these, as I see Lightburn supports it but the machines all say Windows only. Appreciate the feedback.

[@LaserEverything]

Any fiberlaser with EZcad 2 can run on Lightburn, which can run on a Mac.

[@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?

Nope, MOPA is fiber laser + pulse duration settings.

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.

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.

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.

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.

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?

Just a permanent mark with text and logo on anodized parts. What's your experience? Thanks!

[@LaserEverything]

A fiber will certainly be the best at yielding white results on anodized parts, especially if you're looking for any actual depth. CO2 does okay but ONLY removes the anodizing and reveals the base metal underneath. If the base metal is shiny or silver that's going to be the color of the final mark. Diodes do the same exact thing but significantly slower. I'd say fiber is the way to go.

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.

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.

[@TheCloserUT]

@@LaserEverything What are your thoughts on a company like SALE San Antonio Laser Engraving? They offer their laser and a weeks work of training. They told me all I need is a 30 watt as 50 w would burn material?

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.

[@JD-RetroRideCZ]

Hi, thank you for great video. I just have one question about MOPA vs standart Q-Switch JPT. Some videos tells you that MOPA is way slower than Q-Switch - but, is it slower befouse of colloring or even with same settngs ? Lets say 80 khz - will it perform same ? 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.

[@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.

Great video. Do you know if the rocker switch actuators (paint coated ABS) can be engraved with fiber laser? Thanks

[@LaserEverything]

ABS can be marked with a fiber laser on the surface, actually comes out pretty good :)

[@ibrahimbayri7290]

@@LaserEverything Thank you. The one I am looking at is black paint coated white ABS. Do you think fiber can remove the thin layer of paint?

[@LaserEverything]

Should do okay yeah. Might take a little trial and error.

Can TPU be laser engraved?

[@LaserEverything]

I guess it would depend on the specific TPU and who manufactured it, and what was added. To be safe, I'd try and get an MSDS to confirm safety. Type of laser can also have an impact on safety in terms of byproducts from the mark, UV potentially being more safe. We'd have to dig into it more, can't say for sure

[@dpsunil]

Very informative video! I have a question, is it possible to engrave complex gray scale bitmaps into mdf with a co2 galvo? For example a wood grain texture bitmap ? How would you load said grayscale bitmap into EZCAD?

[@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

[@Vemovemo1]

I have a question: what do you think of Raycus QS fiber laser model? it´s cheaper, it´s smaller, less frecuency range. We will use it in jewlery proyects, small area 110mm, silver and gold most of the time. Do you recommend it or it´s best to expend more in a QB model? It´s a 2k difference between models in my country. Thank you! Great content, suscribed!

[@OldePhart]

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 so much love the cool factor of galvo but it seems so limited. So much to learn. Is there a good market in used models that is worth pursuing or are they done when they reach that market?

[@ENDKONTROLLE]

Hello First of all I find your videos great, I can not speak good English but much I understand 😊 One question and I hope you can help me or someone who reads this. I now have a fiber laser with the JPT M7 60W Mopa module now I downloaded a file from the site Freeimage went without problems but now I wanted to download one again, have tried 2 3 different, it no longer goes, lightburn hangs up completely I have to stall it with task quit otherwise nothing happens more...😣 Do you have a tip or idea? Thanks in advance. Greetings from Switzerland 🇨🇭 Roy

Very nicely done. I'm very familiar with my 60w CO2 and UV laser setups but am new to 1064nm Galvo lasers (just bought one) since I need to do metal marking. Excellent Presentation - New Sub! 😀

[@LaserEverything]

Glad it helped! :D

[@joliversa]

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.

Hi, I am interested in joining the laser Master academy. I just wanted to know, are the settings shared designed for any specific laser? I have a 30w fiber and I'm just wondering if the parameters will work efficiently for my laser

[@LaserEverything]

The parameter library was designed for a 30w laser with a 110mm lens but it comes with a converter spreadsheet as well to help get you in the ballpark if you're using a different wattage laser or lens so it should work for you either way. The parameter library gets you close, does about 80% of the work for you - but every laser is different and it still requires some work from the user to dial in.

Can you engrave pvc cards

No, PVC releases chlorine gas when engraved.
