Great work as always. You can also set your "line-up line" as Tool 1 or 2 (so it's not engraved but always there) in a "Master File" and use "Save As" for different files.
Thank you for the great content. I am a total noob to lasers. Just purchased a used OV Laser 50w fiber with 110mm lens and rotary attachment. Your videos have helped me a great deal to understand the whole process and to get it set up and running properly.
Glad to hear it! Congratulations on the new laser!
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.
Today you outdid yourself; great job, especially with the technical side of things. Thank you.
Glad you enjoyed it! Thank you :)
Thanks Alex, you put a lot of work into this video.
Thanks Cormac!
I learned a lot today. Like always, great content.
Thanks, glad you got something out of it!
Excellent, I’m learning things from your videos! Keep it up, dear!
Okay will do!
Thank you for the explanation and coverage. Very useful. Kind regards Gavin
Glad it was helpful!
bless all y'allz for doin what you do in such honest detail
We appreciate it!
That was very useful and elightening. Thank you!
Thanks for watching!
Thanks a lot. Can you do a detailed video on which laser does cutting of various materials like acrylic, steel, aluminium, wood, paper, plastics as well as marking or engraving of those materials including opaque and transparent?
Amazing information. I had no idea how much I didn't know. Thank you!
Glad you learned something, thanks for watching!
Excellent content, thank you Alex!
Of course, thank you!
Very interesting, thanks
Very well explained, keep up the good work!
Thanks a lot!
This is a fantastic video, thank you very much.
You're very welcome!
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! 😀
Glad it helped! :D
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!!
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!
Ended up getting 60W MOPA JPT E-M7 from DTC Lasers.
Thanks again for the content. It’s the best out there!!!
super helpful, thank you!
Glad it was helpful! Thanks for watching!
Wow, great explanation of these types of lasers. Exactly what I needed, and gives me a better idea of what I might want to buy someday. Subscribing...
Glad it was helpful!
great video!! thanks
Glad you liked it!
This video was just what i needed, i was operating a UV laser, and noticed i couldn't adjust the power, so next stop, i now have a direction ! Thanks A million
Glad it helped!
Thank You from this newbie!
Of course, thanks for watching!
5-star content! Thanks!
Glad you enjoyed it!
Thank you for a great and very informative video! How would I find my laser dot size pre-expander on my Galvo CO2?
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.
Thank you this was great
Glad you enjoyed it!
Mopa M7 60W installed today. GREAT info!
Great to hear!
Thank you so so so much man. I know nothing about this stuff and I feel a lot better now.
Good, that's what I wanna hear!
👊
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?
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.
I have just found this channel. I do small woodworking projects and I want to be able to engrave the wood with names ect. What can I get. Least expensive but still good quality if there is one. Thank you for your help
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?
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: czcams.com/video/EB40S6AEVwE/video.html
I know this video is old - but man, it is awesome!
Thank you! 🙏
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?
on galvo I will get a similar effect as on the diode when marking photo on ceramic tile?
Wow, so much info. Do you think there might be a chart we could use for a reference? My head is spinning lol
I'll definitely look into that.
I am looking to purchase a fiber laser for deep engraving into stainless steel. .030 engraving depth. What would you recommend? Thanks!
excellent video, might be older but very informative for anyone concidering purchasing a laser.
Glad it was helpful!
Put together very skillfully and hugely informative. Thank you sir!
Thank you! And thanks for watching!
What are your thoughts about the ComMarker B4 - new 20W fiber....but with a Max source inside?
Hello Sir, Can you also discuss about the application for Infra, Green, Pico laser? thank you.
Perhaps down the road that would be interesting
Thank you just a question can i make a stamp ruber with mopa
What type would you suggest for polymer stippling?
Thanks a lot
Most welcome
a lot of great information, thanks @lasereverything !!! I really appreciate the information about the CO2 galvo head & beam expander math. Are all co2 galvo beams 3mm before they hit the beam expander?
Glad you got value from the video! Co2 RF sources don't all have the same beam size from the source, so that will be something you need to validate on each model specifically. Some are similar, but not explicitly the same :)
IMHO a discussion on 3D galvos is needed in 2022. Which I guess will also increase the attractiveness of EZ CAD 3...
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
This video gave me great insight into galvo lasers...I want to cut .062 stainless steel sheet...what wattage fiber galvo laser will I need...thanks
As much power as possible. The 50w LP or 60/80w M7 units from JPT at a minimum.
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 :(
Thanks for the precise and simple explanations, I plan to purchase a 50w jpt laser, on some websites I see Galvo head and on other websites SIno galvo, is there a difference between them?
Thanks!
Sino-Galvo is a brand name and is regarded highly in the community as the quality option.
Thank you for the great content! I just subscribed to your channel.
I went through your video list and saw reviews of some laser systems but could not see a video on the xTool F1 which I am considering buying as it seems to be able to do what I want to (metal/glass engraving, making small stuff to sell at craft shows). Just wondering if you did one on it and what’s your take on the F1?
Thank you again for your effort in creating such awesome content.
We have one coming but haven't had hands on it yet, unfortunately!
😃👍Danke für das Video
bitte schön!
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!
Is it the same between galvo for fiber laser and uv/co2?
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!
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/
@@LaserEverything Many thanks!! checking iut the link now.
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.
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.
Fantasrtic video, thank you very much for sharing ;-)
Happy to share. Thank you for watching!
@@LaserEverything Watching the whole day your videos, just amazing what you have set up here... Will become a member of your LMA, that's for sure ;-) ... keep it comming...
@@petermican Thank you so much!!!
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?
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.
Alex... If I'm looking for a low cost machine dedicated to etching on powder coated tumblers (removing the powder coating) without requiring a rotary tool, what would you recommend?
PS... Your videos are fantastic.
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.
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.
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: czcams.com/video/0F7MUdZKTy4/video.html
They're significantly more expensive but cutting 3mm silver on a galvo laser like the ones in this video would take hours per piece. For example check out us cutting precious metals in this video here: czcams.com/video/FHOZWlvnu4w/video.html
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.
Thanks! Don't second guess your choice, Raycus are good laser sources and will be more than adequate. Hope you have a lot of fun with it!
very informative
Glad you think so!
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?
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.
@@LaserEverything Thank you very much, I will check it out :)
Hi folks, anyone know this answer to an EZCAD question please ? I want to reduce a DXF by a percentage rather than alter the size in the boxes. I have a load of big files for one model im making and each time I load it would be super helfull to reduce each by the same %. Thank you. Bones
Have you tried inkscape or illustrator, and then importing a resized copy? That's probably how I'd do it. Ezcad's vector editing tools suck.
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.

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.
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.
Great video. Do you know if the rocker switch actuators (paint coated ABS) can be engraved with fiber laser? Thanks
ABS can be marked with a fiber laser on the surface, actually comes out pretty good :)
@@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?
Should do okay yeah. Might take a little trial and error.
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?
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.
I want to engrave white and color ceramic food bowls.
Would be a 20w fiber galvo laser be a good choice for this task with a budget of 1000-2000$ (gweike g2)?
As far as I know, fiber lasers should be capable of ceramic und have good speed as I plan to engrave only one piece at a time.
Is this a good choice or would you recommend something different.
Thanks
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
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.
@@LaserEverything ok awesome, thank you for your response!
Looking at laser for stainless steel markings on charms..will this work
Yeah absolutely, what you want is a fiber laser. Highly recommend the mactrons linked in the description - for even more options check out the buying guide - also linked!
If Lightburn starts supporting ezcad 3 , will I be able to upgrade my fiber with the ezcad 3 board and at what expense
You could, for about $1500 - but I don't know what benefits - if any that would provide. It depends on which features of the board Lightburn does or doesn't support. We'll have to see. A lot more info is needed before I can make a recommendation.
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.
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.
@@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?
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.
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.
Not only eyes safety, Larry: I am highly concerned with the fumes of the evaporated materials... They could be toxic !
We have a very good exhaust system that keeps fumes and debris out of our lungs :)
I Want to buy a 50W JPT fibre laser. You never mentioned anything about the electric Z-Axis / Autofocus. Is it worth the money? or should I just buy a manual one.
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. Some people love it, some people absolutely hate it. Personally I prefer the manual wheel style but I know folks I respect who swear by motorized. Up to you.
Hello
I follow your channel here in Brazil.
How to configure a 175mm lens in lightBurn, I've only seen videos on ezcad, I'm having difficulty doing it.
Check out our playlist for the Lightburn for Galvo series. You can find it by going to our profile and then the playlist tab and it will walk you through everything :)
What would you recommend for preventing oxygenated. What do you recommend for sheilding my containment? It is already built.
We can't really get into it in the CZcams comments as it's not the best place for more intensive support threads but we do have a few options where you can get help. Either check out Discord Server or Facebook group - links in the description - or you can check out our new forum over at www.lasereverything.net/forum and I'm sure we can get you pointed in the right direction.
Can u suggest me a laser machine to remove the coating of a mirror?
What lenses do you find to be the most useful for a fiber laser? I have zero experience with these and I’d like to get a well rounded set to go with my first machine, a 50W JPT. Thanks!
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.
I have only had the laser for a few days and have been able to engrave my name in the back of an old iPod. I knew nothing about hoe the machine it self worked, how to use ezcad or how to make files ezcad could use. So far the Laser Everything videos I have watched have given me a general understanding of all of the above. I have followed the videos and set up the machine and done the calibration, am working my way through ezcad and am trying to figure out if I am going to use InkScape or Illustrator. Keep up the good work Alex.
@@LaserEverything I don't have it all figured out yet but I am already looking at building a lens collection. Mine has Opex lenses.
Hi, Which laser is best to engrave on rubber like Apple watch band? UV laser, Fiber laser, CO2 laser or Diode laser? Thank you.
UV for sure!
How is your 30w Mactron holding up?Thanks for all that you do
Both my original 30w fiber that I've had since 2019 and the 30w CO2 Galvo are doing extremely well. Nothing outside of the scarce typical maintenance required, no major servicing needed. Very happy with both :)
I saw the LMA/LE video with your 60w JPT M7. Is yours a MOPA, and are you planning any high frequency content?
All M7 sources are MOPA lasers and yeah at some point we'll be digging into what that entails and how they can be used.
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
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: czcams.com/play/PLoBR3k35202Yjc1yMfPZsY8EDh_pmcaa2.html 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?
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.
Hi, Great video. Just one question: Do you know if you can engrave Stainless Steel, or any metal, with a 30W CO2 Galvo laser, using Brilliance or Cermark? Thanks.
You should be able to, yeah. I've seen it done but haven't personally tested it myself.
@@LaserEverything OK, Thanks.
I have a question. Would you buy a 50watt Raycus or a 30watt JPT? My budget only allows for one of these. Thanks!
If you want to do deep engravings I'd go for the Raycus. If you want to do high fidelity work with fancy finishes, some plastics, and metal annealing/oxidizing I'd go for the JPT.
Great video! Too bad I didn't see this video before I purchased my fiber laser. I would have made a different choice.
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
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.
@@LaserEverything thanks dude, will try on my CO2
Hi bro that's some awesome video.. However I have a problem.. I got this Hans laser g20 I got it from a friend.. It didn't come with control laptop..and dongle now am stuck with a tool I can't use.. Well not completely am trying to run a different controller.. I bet you know a bit more about controller.. How do I get it to link with my laptop.. Can I use ezcad or is there a hack I could try.. Please help
Not super familiar with their equipment, sorry we don't have any more definitive details to assist with. Its possible you may be able to re-wire it to run on something like an ezcad2 control card and ezcad 2 software, or lightburn. We have a video where we swapped from ezcad3 to ezcad2 control cards, that might offer some help. czcams.com/video/zv1vNfdD0XE/video.html
I had my fiber galvo head go bad anything that I need to do other than making sure my existing still run correctly?
You may need to re-tune your timing/delays after the head swap.
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.
Any fiberlaser with EZcad 2 can run on Lightburn, which can run on a Mac.
Any opinions about gainlaser UV laser?
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?
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.
Is ezcad board an alternative to ruida controller? Do you have experience with ruida controllers
It is not. Ezcad controllers are specifically for galvo operated machines whereas Ruida controllers are for gantry operated machines.
how much $ is eazycad?
where to buy?
Need more information about rotary attachment
Hello sir, I've worked in a company that use donggu uv laser with ezcad program, raycus laser source, I have problem :
1. When I'm click light (F2), the blue square marker doesn't show up.
2. The ezcad software became expired and return to demo version.
The maker of the machnine just told me to bring to the default setting, I did it and nothing happen, those problem still occur.
Can you tell me what or which part I have to setting or repair ?
Thanks before.
Can you join either the Discord Server or Facebook group so we can take a closer look at your issue please? Links in the description, thanks!
Are the raycus 50w fiber 4 axis rotary for $2290,17 free shipping a good unit and purchase all in one unit or portable??
sounds like a good setup but the price is a little low honestly

Highly recommend checking it out!
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.
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.
Can laser Galvanometer oscillate at 16khz frequency??
Thank you!
Love my 1300x900 60/130 CO2……..It’s a hi tech chopsaw😎
Badass!
where do you get your safety glasses sir?
