Too many years as a pilot has left me with some hearing issues that come into play when using your method of finding my focal point. I used a decibel app on my phone and placed it near the site I was lasering. I could watch the decibel levels change as I adjusted the height. Worked like a charm. I’d like to use the twin red light lasers to assist focus but I haven’t figured out how to turn them on.
Very clever! Nice problem solving! Check under the lens while looking up at it from below there's usually a little plastic toggle switch on the galvo head housing.
I know this video is already a year old, and laser engraving has been out for several years now, but I just got my 1st laser platform, an OMTECH 30W split, and had no clue of the setup. I've watched a ton of your vids now and this video alone is already worth the Patreon sub. I am now a patron and will continue to follow your guidance. I am an FFL and I believe a lot of your videos, that I have yet to see, will point me to the right direction. Thank you so much for all your hard work!
went through this a couple times and now my laser is marking a 20x20mm square at exactly 20x20mm. Such a great setup video. so glad I went through it! thank so much Alex.
Just got my fiber laser in on Friday! Found you today when setting up, I got lucky and my laser worked pretty well out of the box but I’m gunna rewatch this and really dial it in. Also about to join that patreon soon as well. Thanks for the great video. I’ll try to pop in on the discord soon as well. Excited to see what this thing can really do.
Awesomeness Video!! am very new to lasering, and am trying to learn as much as I can before I buy my Fiber Laser 50W with my taxes...will definitely become a patron...Thank you Professor Laser!!
Glad it's helping you. Don't forget the Patreon is closing at the end of the month so make sure you hit us up at it's replacement, the Laser Master Academy: masters.lasereverything.net/
oh great! Here in Peoria for LBX I and trying to talk myself OUT of a fiber laser to go with the diode and the CO2 and here you are, showing my easy it will be! When I stop by the tent again tomorrow someone is gonna have to buy me a drink!
Just bought 3plaser 20W basic. I’m sure that what you’ve shared is going to be really helpful as I have no clue what I’m doing. Thanks for taking time for newbies like me.
Great Starter video. Received my first 100W Fiber this week.. and have been lost... This was a great start. Learning LightBurn though... so will be looking thru those videos.
Wooow Man Yr teaching makes people's really educate with Yr fully passionate teaching.. my entire life I never watched more then five minutes videos. But Yr each videos even 2 hours doesn't made me to miss any of Yr word which is very informative and made me to get professional with Yr teaching.. really respect for you n soon will join ur channel.. what is patreon.. they are parameters the 1 u uploaded and all material and its clearance ot white or black can make it on the things.. well there is still so much to learn from Yr videos.. am a very much beginner in this field.. and I have bought this laser machine an year ago but doesn't know how to work with any of them.. but as Yr channel made me start working on it.. love Yr each video bro.. thanks again for everything..
Hey brother, I am researching fiber laser and your channel has been very helpful in educating to this whole new world. I am going to continue watching your videos and hopefully I will be able to find me a laser that gives me and my small business good value. I will be engraving urns (that urn video you have is actually how I learned about your page) so any and all advise would be very helpful.
So, I decided to pull out the lens that came on my laser, just to make sure it is a 200mm lens as it is supposed to be. I grabbed the lowest part of the lens, and that started unscrewing easily enough. But what came off was some sort of thin retaining ring of some sort. Not the lens itself. So while I am looking at this thing in my hand, out drops a lens that hits the metal plate of the laser. Didn't shatter it, and no damage that I can see, but darn. Wasn't expecting THAT to happen! And come to find out there is a rubber o-ring seal, that came partially out of the track. So guess I can't stop now! I tried unscrewing what I thought would just be the lens in the sleeve, but that wasn't budging. I was, however, able to get the sleeve out of the galvo, with lens inside, so in order to put that lens that fell out back in place, I was pretty much committed to remove what I could so I could work on it more easily. So here is the thing. Does that lens HAVE to go in one way rather than the other? Is there an upside down rather than rightside up? I figured I had a 50/50 chance of getting it right, so what the heck. Got the o-ring in the groove, and the lens back in place so I could screw the retaining ring back on. Inspected it with a flash light and appeared to be some dust on the inside. So off it came again, so I could use my air can (for my camera lenses) to blow off the dust, and lightly brushed it with a microfiber towel. While all this was going on, I put the rubber lens cap back on, so I wouldn't be putting my fingers onto the lens while fiddling with it. Went over to the house to bring my laptop over so I could make sure I didn't screw something up with all this going on. Yeah, I am sure you know what is coming. Set up a test image, and fired the red laser. Hmm. Nothing. Maybe I had the focus out of whack? Nope, that didn't change anything. Well heck, fire the main laser! Still nothing. But what was that burning smell? Aarrghh, that was the lens cap getting a hole melted through it. Damn... So I pulled off the lens cap and tried it again. Darn, that red laser still didn't look right. And neither did that main laser. Matter of fact, it wasn't really engraving into the test metal at all. Just a bright line, that was barely bright. Well, come to find out, when I burned through the rubber lens cap, it left a light residue on the lens itself. I lightly wiped it clean with the microfiber again, and by now thinking I had somehow already ruined my brand new laser, ran a test again, thinking I was wasting my time now. Luckily that seemed to fix the problem. Red laser outline was nice and sharp, and firing the burner laser cut the image into the test metal like it was supposed to do. So a couple of questions: (1) Do I just need to put more muscle into screwing that lens out of that sleeve? I sure as heck don't want to make matters worse by breaking something. And (2), about that lens that fell out. Is there a right way and a wrong way for it to go back into place on that lens? I couldn't see anything obvious to indicate that by looking at it. I do have two other lenses I could take apart, if necessary, but obviously I am reluctant to do that if I don't need to. Obviously the laser is quite sensitive to contamination on the lens itself. And again, any way around having to provide a phone number to sign up on your discord server?
1. Yeah potentially. The entire lens and it's housing should come out of the galvo head. I don't know how they got it in there so tight. 2. F-Theta scan lenses are grouped lenses made from multiple glass elements. Depending on the element that fell out it could either have or not have a proper orientation. Usually the final element (the one closest to the table) does not have a specific orientation optically. Some manufacturers put the anti-reflection coatings on the final element while some put it on a glass shield that shields the element from damange. Obviously we want that pointing out, not in, but I'm not sure if I could even tell you what to look for as far as making that determination. I guess if it aint broke don't fix it. 3. Since the discord community is an official "Discord Community" we have to have the highest level anti-bot/spam measures in place so I don't currently know a way around that requirement. There are temporary phone number services online you could try one of those.
@@LaserEverything Thanks for the reply. Yeah, it was the glass element closest to the table that fell out. Why it didn't shatter or crack hitting that aluminum platform is probably a miracle. Sure got me all flustered, hence leaving the rubber cap on trying to fire the laser and burning through it. Duh..... I approached CloudRay about this and they asked me to create a video to show them what I am talking about. I am pretty sure RU-vid doesn't allow embedded URLs, but if interested, this clue will get you to my video -> v=bQRwjZ4auGM Been meaning to get back over to test the laser some more to see if anything seems amiss, but the past few days have had higher priorities. The wife has health issues and we have been bouncing around between emergency rooms and the oncology center, or she just doesn't feel well and I want to stay close by. Truth be known, I wish I hadn't allowed her to talk me into getting this laser right now. :( Anyway, I sent CloudRay the link to the video and am approaching this as being a defective lens/galvo adapter. I bought a couple of extra lenses, but I can't use them because of that 200mm lens stuck in the adapter. I am sure I can take the whole shebang out of the galvo and put it on the workbench, and one way or another separate them, but no promises there won't be some resultant damage. I have found that when removing filters from camera lenses, you can actually squeeze the filter ring TOO hard and it makes it more difficult to unscrew the filter as it goes egg shaped on you. Consequently, I put a very small dab of gun grease on the threads now, and that problem just went away. If CloudRay balks at replacing the lens/adapter as a warranty item, I may try to get them to compromise by giving me free shipping and I'll just buy another one. Likely there is dust inside my old lens now anyway, and a replacement lens only costs $50 direct from them. I'll see what I can do about signing up on the discord server. Seems more and more places are requiring codes being sent via text on the cell phone lately, so I may just be fighting a losing battle against the inevitable.
Omg!! Thank you so mucho for those tutorials, I just got my machine. I haven’t figure it out why I have a button on screen that’s says NOT READY. I haven’t been able to engrave anything!!
Not a great sign but hard to diagnose on RU-vid, check out our Discord server or Facebook group and include as many details about your setup as possible including photos and we'll try to get it figured out. Links in the description.
They lost my laser in the warehouse so they are upgrading me to an autofocus laser (and including another lens) to compensate me for lost time. Can autofocus be trusted? Do you have a lot of experience with this? Thanks.
@@LaserEverything Incidentally, the autofocus has been fine. There is an attachment to move the galvo up and down and a focus button that can simply be held down to set a new focus, like when you are changing lenses.
This video was awesome. I am running into the issue that I don't have a preview, and when trying to mark I don't get anything happening at any point of the vertical movement.
Nice video , I have a 60W JPT M7 MOPA with several lenses and EZCAD 3.0 just starting to learn , have you made videos using EZCAD3 suitable for my machine also?
Hi Lars, i had your machine , it is the second fiber , first is Raycus. So I am still learning, but if you need help go tell. By the way, does your unit run cooling fans only when get hot or is always run?
Could the 160mm focal length lens with a 110x110 marking area that was pre-installed in my equipment be replaced with a lens that would increase my marking area to 150x150? Should I be looking for a lens with the same focal length? Or, does a different marking areas necessitate a change in the focal length?
Different marking areas necessitate changing the focal length, don't try to focus on the focal length when picking a lens. Just focus on the marking area all similar sized marking areas are going to have similar focal lengths so you don't even need to worry about it just focus on the marking area and call it a day. Definitely pick up a few different lenses they're super cheap and allow you to do much more than just having one lens and relying on that. I recommend the cloudray f-theta lenses for fiber lasers. You can view them on my online buying guide: www.lasereverything.net/buyingguide Hope that helps! Let me know if you have any questions. -Alex

Here's an explanation video about lenses: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iAgj6T4eH80.html No part of a fiber laser should be frequently damaged and need replacing. There are very few moving parts.
Thank you for your videos 🙌🏾. Which lens would you recommend 220 or 110? I just got a 20W fiber laser bug what's the difference in lenses? Do you have video on that?
I do have a video on that, here's the link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iAgj6T4eH80.html&ab_channel=LaserEverything PLEASE do not buy a 220 lens for your 20w you will hate it! The 20w doesn't deliver nearly enough power to mark anything at 220mm. I can hardly use my 220 lens on my 30w machine without issues. At 20w you want to stay between 50 and 150mm max. The video I linked explains it all in a little more detail. Of course I'm happy to answer any other questions you might have - just let me know :P And thanks for watching :D
Nice video , I have a 60W JPT M7 MOPA with several lenses and EZCAD 3.0 just starting to learn , have you made videos using EZCAD3 suitable for my machine also?
95% of what we cover in EZCAD2 is compatible with EZCAD3. In a few cases a button might have a different label or be in a different spot but the vast majority of the settings (converted of course) and techniques will be the same. For more information on your specific machine join the discord as there are many members with your exact source. You can also support the show by joining the patreon which includes instant access to my entire fiber laser library as well as a converter to convert the settings for your 60w unit. The converter would be quite useful when watching my videos to get you close to what I'm getting on screen. Let me know if you have any other questions - link to the discord and patreon are in the description of the video.
Hi.. Loving the simplicity of your tutorial. Can i ask about the Max and Min PWM on my machine. I've been told it's an "F-Tech FO-30 150 X 150". There is a plate on it with the model number DRK30F Can you advise please? :)
It has less to do with your machine model number and more to do with your laser source model number. You need to find out if it's a Raycus, Max, or JPT. If you Google that model number you should be able to figure it out.
I’m new to the laser world. I’m purchasing a laptop to run my laser. I don’t want to over buy! Putting any saved money into fiber laser. Can you recommend a laptop to run my laser
Thanks for the great info Alex. i set mine up with this video. Only problem im having is that the save parameter doesnt show on my windows, its past the screen at the bottom. iv tried scrolling, dragging and zoom but i cant get it to come up??? Any ideas?
One of the many downfalls of Ezcad is it's window sizing. You SHOULD be able to drag it out into the main work area to undock the window. If not you may need a bigger monitor (or a TV would work) to get the screen to expand enough to grab it. Super annoying. Highly recommend you look into upgrading to LightBurn, we have an entire free course on the subject. Much easier to use.
It's for use with batch jobs so if you have to run the same part over and over and over and over again you can just swap the part out and press the pedal instead of messing with the computer
Hello! I did settings and I got 200x200 square which is 99% perfect. The issue is when I try to put smaller square like 50x50 I get 48x48...like the machine isn't scaling properly! Do I need to do the Corefile calibration because I don't have any of the correction file loaded or there is some settings I can tweak? Thank you in advance.
Yes exactly. This video came out before our corfile corrections video so we didn't show it as a solution at the time of recording but a corfile would go a long way in correcting this issue. I highly recommend you try one out. We have a great video on it here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-llflAf0G62Q.html
Hi I watched your tutorial and it is the most concise tutorial I have seen. However I have a new computer with windows 10 with 64 bit and I cannot get ezycad to work on it or lightburn, none of them work, can you help me out please. Kind regards Jen
Just got my fiber laser on Friday, set it today watched video and I'm having a problem ????my laser won't fire ??? Go to mark and nothing?? What do I need to check ? Drivers and fiber laser all installed and showing on my computer. I was watching the video and i was at the part where I'm trying to find out my focal point and this is where I got stuck .no marking of any kind . Please help.....I also also your site I need help
Just purchased a 50x50 lens so I will be using this method to get it working properly. Weirdly my fiber laser came with a 115x115 lens according to the lens label but the manufacturer set the machine up to work with a 110x110. I have never been satisfied with the performance of my 30W laser and I am beginning to think that the mismatched lens is the culprit. I have a feeling that the manufacturer had this odd lens laying around and decided to skimp out instead of using a proper 110x110 lens.
It's not uncommon to see that slightly different lens size. Lens sizes are generally the same when being manufactured, but the small differences can keep them close enough to match spec for a 110 focal distance. Not sure on the cause or reason as to why it ends up in that place, but we do see it from time to time. 110 is a pretty good general all round lens size (or thereabouts), but if you need more kick, a 50 or 70 will certainly give more mileage for the same power source. More punch for sure!
Hi there I'm using ezcad2. When I turn on the red marking, my laser starts making a square of around 70mm size. I don't know if it is something by default or not because I cannot change it. Kindly guide me. Thanks
Awesome video. Quick question. Do you have to adjust the focal point depending on material thickness every project? Ex. 1/8” metal vs a PMag thickness.
Afternoon, I am tryiing to make these adjustments in ezcad 3 but cannot find where to do the feild warp adjustments. I believe i found it, but when I make a change, nothing happens. Could you direct me to where I need to go to make these changes?
Check your Ezcad folder for the "Calibration Wizard" and run that, you can follow the same directions we give to ezcad 2 users for lens distortion correction here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-llflAf0G62Q.html
Hi I changed my lens and I adjust the red point light as you explain in this video, so then if I mark a shape and then I light it, the red light perfectly fix the shape. However, when i don't light the shape, the pointer is not centered; in other words, if I would like to mark a circle around a point, i can't just use the red light pointer as the center of my cricle. Is there a way to fix that? Thanks and congrats for your videos, they're so helpful!!!
I have a brand new fiber and on my small test images or text only half is focused. Right half is darker and louder when marking. These are pretty small test prints so i'm not sure if its out of level inside somewhere, the workspace, or field warp adjustments. What should i check first? I marked a big test square on stainless and it looks square and oddly enough marked pretty even. But the smaller hatched images did not. I'm very confused
The first place I'd look with this issue is actually the galvo scan head. Get a level and check the scan head, then check the bed. They should match. They do NOT need to be level with the ground, just level with one another. If they are not you should be able to loosen the bolts on the scan head at the neck and adjust accordingly.
The setup for ezcad2 and ezcad3 are virtually the same. At some point if I get a laser that runs three I'll make another video but it's really unnecessary. They're very very very similar.
I have like 5 $25 ones scattered around that get abused and forgotten about and a nice pair that stays on my desk and doesn't leave. Up to you - I use both and don't often run into a situation where I NEEDED my nice one but it doesn't need to be tared as often and the batteries definitely last significantly longer.
Had an issue this morning and my computer died. Now I've plugged in a different computer but I'm getting the dreaded "Can't find dog, software will run in demo state". I seem to remember there was a driver I had to download to run Ezcad 2 with my laser. Is there a driver file available that you are aware of to get me running again? Thanks!
Hi! Where can I check the size of the lens my machine came with? On the lens it only says CSDQ f-theta lens 1064nm f=210mm 210C24630. I understand the focal length is 210mm but not sure what the size is. If someone could help I will highly appreciate. Thank you! * on the machine’s manual it says “processing area” is 15cmx15cm. Can I interpret this as the size of my lens? I am new in all of this :(
Have you ever had a "Not Ready" buttom that shows up in the bottom center of the screen. I am a new EZCAD2 User and I am getting this after install. So I have not been able to use my laser cutter yet. Any advise? Thanks.
New to fiber lasers great videos I bought a used sfx50gs laser it's marked jpt my question is how can i be sure its a true jpt and not jist a sticker claiming to be will the settings allow me to change a frequency like 600kh if it's not capable thank you
JPT sources have a very specific look and the fakes are not convincing. If you send some photos in our discord server we can verify its genuine but if it has a sticker I honestly doubt it's a fake
Thank you for such a great video. One problem I am having is I am setting up a 150x150 lens. Have all the distortion taken out and it makes nice straight lines. I made a 120x120 box while setting up everything just to make checking the straightness of the lines easier for me. Problem I have is that the box actually measures 122.5 on the x axis and 131.5 on the y axis. I know it has something to do with the scaling settings in the configuration. But every time I've tried to correct this things go south, can never get it to be a perfect square. Negate is NOT checked on either galvo. If I go into the scaling drop down menu and enter the desired marking and actual marking settings for galvo 1. Then do the same thing for galvo 2. The parameters that I enter in galvo 1 are overwritten by what I enter in galvo 2. What the hell am I doing wrong?
Well the first thing I'd say is that you want to be making your scale adjustments FIRST and your warp adjustments second. Adjusting your scale after setting your warp adjustments is always going to mess with your warp. Get the scale as close as you can, then the warp, then scale, then warp again. You'll have a more accurate finished product. As far as the overwriting issues go it's really hard for me to tell without looking at it. Feel free to post a few screenshots or a short screen capture to the discord and I'd be happy to take a look for you. There's a link in the description and we can get that sorted. Not a great answer but hope it helps a little!
Hey Alex! I'm following along, and got to exciting part of getting the focal point for the first time, and got nearly all the way down and there was no marking! The laser showed the box but just nothing was marked, advise?
It's really hard to give good support on RU-vid comments, but if you want you can join our free discord server and we can try to help you out over there. Here's a link, discord.gg/eXQ48rhV
Hey Alex, great video!! Just wondering if there is a scan setting with my 30w fiber laser in Lightroom? It appears the lines when scanning are not equal on each side when it is traveling back and forth?? Any idea what's going on??
Looked at the laser Mactron 30w fiber that you have listed from aliexpress and shipping shows ~$900.00 alone. Has this been the case the whole time or do you have any other suggestion/options.
That's just the cost of air freight. You get your laser in a week instead of three months. If you're buying from them that's the only shipping option. With the way the ports are these days you don't want your machine on a boat.
hello.. I also have a 110 mm lens, but my problem is that when I draw something, the dimension is not the same as in the drawing, it is 10 mm bigger i m using lightrburn
Great videos! One doubt. The parameters library are set for a specific power and lense size? I.e. Wont be the same result using the same config with different lense size. Right?
The lens should have either the lens size or approximate focal distance printed on it which we would be able to help you out with if you post a picture in the discord or Facebook group. For the laser wattage there isn't usually much you can do except open the case and inspect the laser source. Most sources typically have a sticker that lists the model number which we could then use to tell you what your laser power would be.
Hi i need help figuring out what size lens i have. It reads on the side “ f-theta lens 1064nm f=160mm 16032091”. I also dont know what to click for the serial in the laser control for parameters. My boss said our machine is a morn 20w fiber laser. Please help.
You have a 110mm lens, please join the discord and we can help you do some investigating to find out the specs of your specific machine, link in the description!
Thank you so much. I got alot of things figured out. One question i still have. Now that i have changed setting to be correct i can hear a humming noise now when i press F1 and i cant hear it when im actually engraving or F2
Great Video, first timer here. I have an Omtech 50w Max Source Fiber Laser Engraver. It came with a standard F-Theta F=430 lense. During the setup video, you mentioned selecting the Source under "Fiber" and "Serial". I believe you selected JPT. I do not see a drop-down for MAX Source, it was already on IPG_YLP, but not sure that is correct or not? I was able to get the laser focused and set at the correct height. I noticed though that my Red Box and actual Mark box are significantly off...i.e. it's not aligned? Any recommendations? Thank you!!
If it's set to IPG_YLP and it's working correctly I would leave it alone. Ezcad was made before MAX sources were a thing. To fix your red box alignment check out this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ip08rkqw9o4.html For everything else related to getting your galvo laser working as best as it can this playlist would be really helpful for you: ru-vid.com/group/PLoBR3k35202YW6uCz5ESGnPbLFe9Ri2ve
Hello, I recently got my 60w laser machine and I would like to know the settings to be able to cut metal plates such as gold or silver , can yoy help me
Great information, i am very new to this, when you go to the( select parameter from library) is this something that you build or is the field supposed to be populated?
I just set up my OMTech FM6969-30S fiber laser engraver. Upon loading the EZCad 2 software an alerts pop up. First that I dont have permission and now that I dont have a dongle and EZCad will run only in a demo mode. I thought I bought everything I need to starte engraving. The manual even says that this dongle is needed. I'm now waiting for the OMTech Tech support to call me back. What are my options and how to resolve?
keeps saying cant find lmc driver and opens in evaluation mode, installed the provided usb key by monport (assuming the key is the dongle) after sales monport phone number does not get answered and VM is in Spanish. Emailed support and went on their chat. also contacted seller through amazon. no help so far
Got my 70 watt laser running thanks to you.But where can I find the folder with the lens settings in it. I have a 220 and I want to go to 110. So I need to copy the folder but I can't find it. Thanks in advance..Ben
In the case of ezcad, you would copy/paste the existing ezcad config, and relabel it to the new lens size, and then update the field settings and import the proper library conversion for that lens size. For lightburn, can just go to the device tab, duplicate the 110 device as a 220 with a new label, and it will prompt you to update the field size if needed. For parameter settings, we have copies of those on our website to download.
Just got my fiber laser and already ezcad can't find dog! bummed, any ideas whats happening here. Did I buy some chinese junk? Is it the 64k operating system? Everything seams to be 32K. Very nice video, but would like this laser to work so I can learn some more from you.
Are you using windows 10/11? If so make sure you are using the LMC64 driver and not one of the others or it won't work. Machine has to be plugged into the PC and turned on in order for the software to function.
That driver seems to be hard to find. Maybe I'm not going about it the right way. Thinking about buying the software so i can get direct support. Other than relying on this company's copy. I have a 60w CO2 laser, this is the first time I went with someone not around me as a distributor. I learned my lesson, took a risk hopefully I can make this thing work.
