[@Langeloudspeakers]

Hi Jeffrey; I may add my experience regarding uneven mark intensity. If the lens is clean and marking area still looks unevenly etched I suggest to check if the optics (galvo etc.) are orthogonal to the marking plane. I had 0,8 deg. difference on the vertical plane...it's enough to have an uneven focus on the marking area.

[@jefferyj]

That's a good thing to check!

[@davidmythalamouth5040]

also the button on top of the scan head activates the two focus alignment lasers

[@lofivibes-techanimestudios281]

Hello, if you don't mind me to ask: Do you think we should go through any course or some material before buying one of these lase fiber machines?. I really like to buy one but not sure if it'll take like some complicated course before start working well. Thanks for your material, very helpful.

[@miszbabyphat]

Hi Jeffrey, it occured to me that the goggles don't block the red pointer, and since I'm engraving jewelry, it something's reflects in my eyes. After working with it, my eyes hurt for days, and I have no idea how to manage this. Do you have an advice?

[@jefferyj]

Did you buy safety glasses for the correct wavelength? I make a point of not staring at the laser while it's marking and I also wear safety glasses.

[@miszbabyphat]

@@jefferyj hi! Yes u did for the regular laser (1064 and goggle are 850-1300) but the red laser point is supposed to be somewhere in the 600 area so not covered. I don't look in the laser while it's operating, I do however look while placing the item and check if the marking is right, that has been reflecting in my eyes a couple of times, and it started hurting after a while

[@kati_franczeska]

I just purchased a fiber laser and your driver installation tutorial helped me tremendously but I'm still having an issue. I get to the very end, click on the folder with the driver, and it says "Windows was unable to find driver." What do I do now? Please help!

[@aytac83]

Hello Jeffrey, What about radiation safety? Is there any serious radiation during the marking? Can't find good information about this on the internet.

[@jefferyj]

I don't have any good info on that, but I suspect it's probably a good idea to enclose the laser with an opaque material. I may be doing that in the future.

[@mmcnama4]

Hey Jeffery- What are the safety concerns in terms of exhaust, protective glasses, enclosure, etc when it comes to a fiber laser? You see a lot of videos w/o dedicated exhaust or an enclosure but I see you've added both to yours.

[@jefferyj]

I use a wen filtration unit with a vinyl hose leading from the workspace to minimize metal dust in the air. It should probably be exhausting outdoors. I use safety glasses from amazon for 1064nm, but as you can see, my enclosure is nothing special. I may build another in the future. One of the big reasons I built the enclosure was to contain dust from marking anodized aluminum. My table would have a thin layer of black dust all over it after marking 100 relatively small black anodized aluminum parts - had to control that.

Haii JefferyJ, have you try to engrave tumbler stainless steel? but the tumbler has color like pink red etc.because i try to engrave black tumbler and the result is good. But when I try to engrave pink tumbler, red tumbler, or gold tumbler, the coat was peel. What Should I correct? Thanks

[@jefferyj]

I don't do any marking on tumblers, but I have heard people complain about inconsistent results from color to color with fiber lasers. I think some people have gone back to CO2 lasers for more reliable results.

[@juanoktorisapela2433]

I see... thanks a lot for your information 😀🙏🏻 now I'm focusing on tumbler work but I'm confused about using rotary. when i use rotary, The results of the engraving on the tumbler are images that do not coalesce or even images that accumulate. is there a video where you used rotary in the engraving process?

[@PatriotCoinRings]

I'm brand new to laser engraving and just picked up a 40w CNC Fiber Laser myself. Using factory settings I can engrave any of those black laser cards for sale on Amazon fine but on any other metals - nearly nothing! What could I be doing wrong? I've looked for a depth setting in EzCad which it came with and didn't find anything, I tried all different random MhZ and power settings and still no change. I can see a very slight marking if I set it to loop 10x for instance but not much beyond that yet the manufacturer shows it cutting deep into firearm slides and such. Of course out of China I'm getting no support so just wondered if any of you experienced engravers might know what I'm doing wrong?

Is that a 40w co2 laser? If so, that would have a different range of materials than a fiber laser.

I need to know how to set that I'm starting to get familiar with it. I've been spending several hours a day playing with the software. not sure how to rotate items like letters and text. Do you have a recommendation? I've seen several other videos out there, but they're terrible. They have music in the background and they're not explaining anything and all I see is a mouse moving from one point to the next, which tells me nothing at all. I've looked on. udemy in the courses in Spanish, which helps me not all. I hope you know something more current than four years.

Hello, can you help me. I have a 50w Fiber laser machine (Oree Laser). The machine stopped marking from one moment to another, it only scans the red laser. I have changed the laser cable and there is no solution, I have restarted Ezcad2 with no solution, I have traveled the height of the head looking to focus, but the machine does not emit laser. What will be the problem? Can someone help me please. Thank you so much. Christian from Chile

[@rpshotty4801]

if you could go back would you have gotten the 50w? I ask bc it seems if your not trying to cut, most of these 20, 30, and 50 variants are often sub 50% power to get really great engraving on aluminum and stainless. since those are the two metals im dealing with and need to mark on, do you see any reason to spend the extra cash on the 50w when the 20W seems to do everything in the 20 to 40% power range. love the vids man. you have been a huge help

[@jefferyj]

For my uses, I'd probably just get a 30w. That said, the 20w has been fine as most of my marking is on anodized aluminum.

[@rodsmartinez2020]

Hello Jeffery Your information is priceless thank you so much! I have been looking at 20 watt fiber lasers locally I found a guy who sell them locally he tried to demo it to me he couldn't get it to work He had the head and adjuster stem on a riser. my question to you is what is a good rough focal length form the center of the lens to the top of the work piece. I saw a 30 watt today that worked great for what I want by the way I want a dark mark on brass copper and rose gold thank you so much!!

[@jefferyj]

There is a split line on the scan head that people normally use to measure to from the workpiece for initial setup. On my laser with the 150x150mm lens, the distance from this line to the workpiece is about 355mm. The length will be greater if the working area of the lens is larger. You can also start at the top or bottom and continuously mark until the light/sound is most intense and you should be within

[@rodsmartinez2020]

@@jefferyj Thank you!!

[@polakis1975]

From your experience witch brand is a bit better to buy. All are from the same factory but still. Split unit or cabinet? Also is it true the more wattage(more marking area) you get less dens marking you have? Thanks a lot!

[@jefferyj]

It would be nice to buy from a supplier who is responsive to your questions and can support the machine long term - although I haven't needed any support yet and have had mine for almost two years. For your second question, the marking area will depend on the lens field. The larger the field, the less power you will have.

[@mikeercc9571]

I’m looking to purchase a 30w 150x150 soon and Iam curious if I purchase one from China off Aliexpress is there usually a extra fee for the import fee? Would you think spending the extra amount to buy one from the US would be less expensive in the long run? Thx Mike

[@jefferyj]

The tariff is at least 25% if you buy it from mainland China. You can buy one already in the US, or you can buy from a company in HK where the tariff is only a few %. Check out this facebook group facebook.com/groups/440091022989424/

[@bkhenry1047]

Thanks for the videos! Will this still engrave if the material isn’t perfectly level?

[@jefferyj]

Yes, it's actually fairly forgiving. Depending on the material being marked and the power settings, you can be out of focus by 0.25mm without major issues. It will mark, not engrave, several mm out of focus also.

[@Deathbyglory1]

Is there anyway to get a copy of the usb data I kind erased it

[@stanz4142]

[@bobreichel]

I bought a 50w fiber laser and don't know how long it will take to get it but I'm wondering about the software. I downloaded several but only one would open. There are some differences to it vs your version. I assuming the laser will come with it's own. Just wanting to become familiar with the software. Enjoying your video learning a lot but can see already there's so much more to learn. Thanks for your videos. Can't wait till it gets here. I got it on Ebay just hope its not a scam as it was quite cheap for a 50w but time will tell. Keep up the good work.👍

[@jefferyj]

If you search ezcad 2.14 you should find a couple download links from cloudray and a few others. There's nothing to install until you actually get your laser with the drivers. You'll be able to run the program and import vector files to become familiar with it, but won't be able to save your work while in demo mode. Also, join these three facebook groups....lots of good info there. Sawmillcreek's laser forum is also quite good. facebook.com/groups/440091022989424/ facebook.com/groups/250911899106529/ facebook.com/groups/300139820848489/

Hey Jeffery I almost purchased one of these Ebay lasers but stopped short as i saw another buyer's picture of warped thin engraved metal, maybe stainless steel. I have 80w co2 laser and it makes thin metal warp when engraving. I read that fiber laser would not do that thanks to the different wavelength but that picture makes me worry. In your experience so far do you think thin stainless (0.01-0.02) can be engraved without warping? When I say engraved i mean permanent mark that can be felt with fingernail. Thank you for your videos Peter

[@jefferyj]

If you have a dense hatch, your part may warp. If you just need to make a quick mark that won't be removed, it might be fine. I can't say that I've engraved anything 0.010"....but I may have some shim stock on hand.

How do you pick a lens for the laser and how do you decide between getting a 30w or a 50w laser - I’m just looking into getting started with fiber lasers. I want to be able to do surface etching and deep etching. I also want to have rotary capabilities for cups/pens etc - thanks for any help you can give me or any sources of good information you can direct me to

[@jefferyj]

Higher wattage will get you deeper, faster. The lens size only needs to be large enough to fit your workpiece. Any larger than that and you'll be giving up power. Some people do choose a 300x300 lens for the wider angle when they're marking cups without using the rotary.

[@TXARMYVET89]

My question is getting white markings mine come out brownish. Also mine has 2 dots you are supposed to align? But why when all my parts I mark are different heights?

[@jefferyj]

I'd suggest running the speed/power grid to get a sense of what different power and speed settings do. You may also want to try raising your frequency a little assuming you're not seeking depth. Your two dots are supposed to converge to find the focal point. This needs to be adjusted to accommodate different height workpieces.

[@spielt-lasertagde]

I just bought myself a 20watt fiber laser and your videos helped a LOT. Thank you. I still would love to have one topic covered and also a question on a strange behaivior of my laser. Topic: photo or pixel based engraving... I do not exactly know why but for me it does not work... Ince i was marking something but since then i only get a plain square all with same intensity and no picture... Maybe wrong file format or setting? No idea. Strange thing on my laser: when using cross hatch in hatches it becomes streaky and sometimes some vectors simply will not mark the cross hatch at all. Especially on single files with several forms in it. My workaround is to create a second hatch instead of using the cross hatch function. A lot more reliable to me... What could be the problem here? Thanks in advance. And greetings from Berlin

[@jefferyj]

It sounds like you may have an issue with filer format for photo marking. For processing photos and other info check out these three facebook groups: N'GRAV'D facebook.com/groups/250911899106529 Fiber Laser Metal Engraving facebook.com/groups/440091022989424/ EZCAD2 Users Forum facebook.com/groups/300139820848489/ For your issue of streaky hatch marks, I could take a couple guesses. First make sure you don't accidentally have an extra hatch enabled (hatch 2 or 3). Next, if you are using "All Calc", disable it. Finally, some streaky marks between marking can be caused by timing issues. Check out my video on timing to make sure this isn't the problem.

[@ArtyomGalstyan]

Ok, but what should i do when I press mark, and nothing happens? It just uses the scanner to show the shape i am trying to mark, but it does not do engraving!

Hi Jeff. I have leveled my laser table with waterpass, and I find that my galvo head is a bit tilting, should I level that too or is it alright that way?

[@jefferyj]

Ideally, the head and lens will be coplanar with the table so you minimize variation in how the laser acts upon material placed in different parts of the workspace. For some applications, small differences will make a big difference and for others it will make no difference. Make some test marks and if you're not happy with what you see, make adjustments.

There are a few companies I know of who sell Chinese lasers in the US...Full Spectrum Laser, San Antonio Laser, and Boss Laser.

Really appreciate your videos and the time you put into making them. I have searched through your videos and tried to look through as many comments as I could to prevent from asking a repeat question. I couldn't find any info about the supplier you used or the process to pick one up. I'm looking for a 50W split laser and having a hard time figuring out where to start. I have seen them on eBay from China for $3600 from a seller with no feedback all the way up to $25k from reputable American companies. $20k+ is outside of my price range and I wouldn't trust a seller from China that is offering one for $3600 with no reviews. I have seen a few around the $6k range anywhere from Amazon to eBay and that's a price I can definitely handle. Any advice on where to look and make sure it isn't someone selling a 20W laser and advertising it as a 50W or any other big issue?

[@jefferyj]

I rolled the dice on an ebay seller for about $3325 or so. It's been fine for about a year, but I received zero support or training and the seller no longer even sells lasers. If you wanted to be reasonably safe, you could contact a Chinese seller directly. There are many and I hesitate to recommend any seller that I haven't used. Check out this facebook group facebook.com/groups/440091022989424/ Keep in mind that it's run by a Chinese laser company so a lot of the people in the group are very biased toward that particular company.

JefferyJ thank you very much for getting back to me. I actually rolled the dice myself about a week ago and bought a 50W from an eBay seller.

I ended up spending more with this seller but their support was awesome and the machine is already sitting here in the US and shipped from California. It shows up tomorrow so I’m excited. I’ll wait to comment on the seller until after I have the laser up and running but they have been great so far

I believe you can remove the powder coat with the co2 laser, you won't etch the metal - I don't have a co2 laser though.

What is cycle time to mark text black letter size 1” X 1”? Thx much

[@jefferyj]

It will depend on the material. If you just want a visible mark, it'll be a matter of seconds. If you're looking for a black 'anneal' type mark on stainless, it could be a few minutes.

Hi, Thanks for the video. Is 20w Fibre laser enough for photo engraving on metal ?

[@jefferyj]

Yes assuming you aren't going for much depth. If you want depth, get a 30w at least, it will be faster than the 20w.

[@dudpktz]

Hi there! Do you know the compay Optic Laser? Any comments on them?

[@jefferyj]

Haven't heard of them, but there are tons of companies selling these lasers. It's a good idea to confirm that the BJJCZ control board is genuine so you can use the most recent version of ezcad2 regardless of which seller you choose.

can I use a Mac computer ?

[@fatkidontheblock201]

I can mark plastic, wood, painted metal but not bare metal any reason why it won’t mark bare sheet metal?

[@jefferyj]

If it's a fiber laser and you're in focus, it should mark metal. Double check your pen settings and focal length.

[@fatkidontheblock201]

JefferyJ I’ve went up all the way and down all the way and the sheet metal I’m using gets a light engraving but nothing dark or deep

[@fatkidontheblock201]

JefferyJ it also burns wood , painted metal , plastic but not bare metal

[@jefferyj]

@@fatkidontheblock201 That's a little odd. If you're using adequate power and a fairly low frequency while being in focus, I'd expect it to make some kind of mark. Did you check if your lens is clean? Also, did you happen to try running the test grid files that are available in the description to this video: kzbin.info/www/bejne/nXLLf3ara817g6c

[@fatkidontheblock201]

JefferyJ I figured out a few things when I adjusted the parameters correctly to my knowledge. The laser body had the parameters on the black plate which told me how to set it and by checking the manual for remaining specs this help get a more noticeable engraving but nothing deep. It did help with the frequency allowing me to go beyond 20,000kgh.

[@garyw.1450]

What did you use for your screen around your laser?

[@jefferyj]

It's polycarbonate with extruded aluminum (8020 type stuff). I'd go with something opaque next time though...

I have 50W Fiber Laser Marking machine with 220mm lens. If I large like 220mm the marking on the stainless steel was very light marking. If I mark small area the will be perfect one. Why like this.

[@bobreichel]

What power source is your laser Raycus, Max or JPT

[@jefferyj]

It's a 20w, Raycus.

I will really appreciate if you let me know what is wrong. Thank you in advance. Nasir

[@jefferyj]

My marking is all for my own items, but other people seem to find work with local businesses for logos, serials, etc.

[@krisknowlton5935]

Blake Libby, I have always made money with every piece of equipment I have purchased. From a sawmill to loaders and a backhoe and all sorts of hand and power tools, they have always made money. So my wife doesn't question the tools I buy. She did one time and that tool made us an extra 5 grand in one week over what we were making and we continued to do over a grand more per week than what we were doing. Now that I am retired I just tell her I am using my cigarette money. I have never smoked! In fact I just pulled the plug on a 50 watt fiber laser today with a rotary attachment.
