*"I LOVE THIS VIDEO"* I've had a 30w Fiber Laser Machine for nearly two (2) years now and haven't engraved one thing yet other than some of those black aluminum cards which seems to be the only thing I can do as a noob because I don't understand settings and the machine coming from China provides no support. This is some great info and I will be trying these settings tomorrow to see if I can find the problem to my delima of not being able to successfully use my machine properly and engrave like it should.
Thank you for doing a good job without any music in the background. Do you have anything that's more beginner-based just got my. fiber laser yesterday.
yeah i run a 50 watt fibre laser and have never changed those spot settings since the machine is installed, instead setting up the desired finish using speed, power and freq and controlling the mark with spot size (typically 0.04) and various forms of hatching and cross hatching say if the material coating is particulary troublesome, so 50hz delivers the most power and then upping to 80 or 90hz for a nice polish (on steel) so just as an example , 0.04 spacing, cross hatch, 3000 speed, 100% power and 50hz for taking a coating off then 0.04, single hatch, 3000, 60 power, 100hz to polish
YOU did a great job brother. you solved all of my laser servicing problem. i am a fiber laser cutting engineer now recently enter into laser marking too.
Like your information on MOPA fiber laser as I just got mine setup and don't know much about it and the book that came with it does not address colors? Rick
Hello JefferyJ, excellent explanation. Would it be possible to see the parameters published for certain "colors" such as RED, YELLOW, BLUE, on stainless steel?
Hi Jeffery, long time since you posted. When you do this graph, when you change parameters in layer parameter settings, do you have to do each layer independently? I have 70 layers and have gone through and changed pramaters in every single layer. Now I have to go back to change mark speed to 500 on every layer. Is there a quicker way of doing that?
THANK YOU - this vid is still very helpful and relevant! I'm looking for more details on how speed + power + frequency impact the depth of engraving, specifically to optimize cutting metals (no hatch, just a 0.3/0.1 wobble config'd for the pen). I can see I need to dial this in for each lens (50W JPT; f100 and f290 lenses). Do you have something like this done --OR have info on how I calculate it? 🍺🦝👍
I have a 50w with a 300mm lens. will i need to make any adjustments to the settings once i download the power vs frequency test grid? learning my machine slowly
Any advice in engraving Silver? I have been trying everything I can and Silver is not engraved at all. I have tried the focus, lowering and making the laser lens go up, nothing works.
Hi ! Very nice videos. Do you know what happens if i set a frequency out of range of the laser source inside my machine ? For example i set 45 KHz and the source has a range between 50 and 80 KHz ? Thank you Olivier
Hi Jeffery! Was it a 20W fiber laser machine use in the test on 3:50? Because I had bought a 20W fiber laser machine as well and downloaded your shared file to do the same test just like 3:50. I was using stainless steel pieces as well but the result was different from yours. It did not show any colour. Please help.
Hey Jeffery, I made a test grid that shows lots of different colors on mostly every material I've tested - how can I get in touch to show you and/or discuss it with you?
Iam working with pigeon rings i have gold color its aluminum coated with gold color all what I can create just white color text . i need black text on aluminum rings , do you have any solution i hope you can help me Note : i hat 20 watt fiber mark machine with rotary Many thanks
Hey Jeffry, I am trying to put a black mark on 11 ga. mirrored Bronze plaque. The size of the plaque is 11.5"x 7.625" almost the size of a sheet of paper. I am brand new at this. I just bought my 60 watt Fiber MOPA Laser. any help with settings or if a plaque this big can even get a black mark would be appreciated. I am using a 300x300mm lens by the way. Thank you FYI I tried to email you but it came back as undeliverable
hi complete newb here so I hope this isn't a stupid question but can anyone tell me If you can change the max Khz in the configurations, I keep trying to make tests with parameters that use 40 or 50 kHz but ezcad keeps telling me the max is 20, so is that it I can't use frequencies above 20?
Hi, Newb here. Where do you get the image for running the test engravings that you did? I have my OMTECH 20W fiber laser being delivered today and could use all the help I can get. Thanks
I have made many setting with the frequency and hatch but i am not getting the proper result - if i print a text called TEXT , the last letter T is not as the same as TEX - why is that , how can i fix that
Nice video. Just a question if I may. If you dont get a satisfactory color on a mark. Is it practical or possible to re-mark without moving the material. Lets say we are working on stainless steel for example. Thank you
Yes you can mark again as long as you don't touch, bump, or move the material at all. For color, the results may be a little unpredictable when re-marking.
hi i have a problem with params i touched some of the ports and settings and the fiber laser just wont work and any other ports i see on youtube dont work how can i fix?
I hadn’t payed attention to that spot diameter visualisation dialog.. good pointer. Another big thank you from me: it’s really great that you are publishing videos of your experimentation since there isn’t much else out there. Is there a shortcut you use when making those test patterns or do you go through the boxes one by one and adjust pen settings?
I've been trying to find a shortcut by opening every file in the ezcad folder that looked like it might store pen settings, but I haven't found it yet. So yes, one by one....very tedious. If you want the file to play with, let me know and I'll send it your way.
Param/markparam.lib has the saved param library- each [section] is a single pen config, but unfortunately while that would allow programmatic generation or just search and replace, you would still need to manually apply a different setting to each pen which is still 75% as tedious.
I really appreciate the video and has helped me understand more about the settings and parameters. Is there a way that I might be able to produce a chart like this so that I can maybe download it and/ or see the different settings for my fiber laser. I want to be able to see the outcome on the material that I use so that I may be able to adjust the settings according to my fiber laser.
Hey Jeff, thanks for the video but do you have any specific parameters for marking plastic? I tried the ones in this video and it didn’t come out as a clear mark it was more of a burnt mark.. can you help me out? Thanks
Check out these two videos if you haven't already: ua-cam.com/video/yQflgf5ylJg/v-deo.html and ua-cam.com/video/eywQfOA7kic/v-deo.html Some of those settings may be useful to you. If your laser is more powerful, tweak the power and speed settings.
Hello! Jeffrey . I have a problem with my laser machine I hope that you can help me figure out. it shown up side down from the real object that I hatched it reversed from the laser. it likes a selfie from Iphone.
Well done. We have many greens, reds and oranges at 25% power in the .0005 and .001 line space range. At 20% power, we did a second pass at 0.001 line spacing and got a nice black luster at 80kHz, and a deep maroon at 60kHz. If you want to get some rainbows, we did a double pass at 20% power, 800MM/s to get brilliant colors at .0005,.001 and .002 across all frequencies.
Thanks for the video. I’m a noob to the fiber laser world and just purchase 50w jpt power source. Is there a place I could download these test patterns or is it something in excad2 I can find?
Links to these files are available in the descriptions to some of my other videos. You can also check out this facebook group: facebook.com/groups/547620632495173
Hello, on the Power vs speed and power vs freq the hatching is not setup. I cant seem to be able to figure out to hatch more then one item on the page. When editing the hatching parameters on right IE Speed, power and Freq then click APPLY and got on to the next and change it. After doing rows, I go back and click to check it and the last info I input in 1 box shows the same info I put in the last. If possible can you explain how to set up parameters and do hatching on the box to show different values. Thanks again for doing these they helped a lot.
I made a video a while ago on hatching; it might be worthwhile to check out to make sure you're doing the same things I am to set up pens and apply hatch settings. Here's a link: ua-cam.com/video/kmxDePbHHOk/v-deo.html
Love your tutorials Jeffery, where do you get your sheets of titanium and stainless from? Need to get some similar stock in to make some cool things? 👍😎
Hi, Jeffery, thank you for your very nice explaination and details for all that. I am new to fiber laser, could you please tell me how to setup the POWER/FREQ/HATCH testing file in the EzCad2(or simply you can upload the testing .ezd file) for us to get the testing done like what you did in the video?! Much appreciation for your help!
I seem to be having a problem with my mark settings and I hope you can help. So far your videos have been the most helpful!! I operate a 30w KT Laser and while trying to figure out the rotary table the other day, the "speed (mm/s)" setting under "Marking Parameters" has changed to "step (mm)". So now instead of the default being "Speed (mm/s) - 300" it reads "Step (mm) - .020". So y question to you is, do you know how to get it back to read "Speed (mm/s)" instead of "Step (mm)"? Thank you for any help you can provide!
I don't have the rotary, so all I can do to help is direct you to a few facebook groups where you might find assistance: facebook.com/groups/250911899106529/ facebook.com/groups/440091022989424/ facebook.com/groups/300139820848489/
hello mr jeffery is have an issue about engraving when i want to mark as it is straight on my pc then when the laser marks it opposite like if i want to engrave MONDAY it engraves YADNOM. i want to reset it to normal please sir kindly assist thank you
Thanks Jeffery, your videos are very useful. Could you please let me know what's the different between Frequency setting and Wobble Distance setting? I'm confused because they both change the density of the wobble circles.
Wobble is used to thicken a line. It will allow the laser to deviate from the 'on screen' path by an amount you set to gain thickness or coverage. Frequency controls the number of pulses in a period of time - the higher this number is set, the less destructive each pulse will be.
When I tried doing stainless steel at first on my 30W fiber non MOPA it was like a brownish goldish color and I didn't like it but now I go out of focus by 3-5mm and it no longer etches the steel but burns a very dark image on the steel. You should try to go out of focus to get that black anneal and also see what colors you can get out of focus. Great videos especially since there is so little out there in tutorials for these lasers in English.
i too have 50W raycus fiber non MOPA, does frequency affecting the result too? because the company said no need to change the frequency because its not MOPA. i really need black smooth marking but never achive it, always looks goldish color. Please help me..
@@rumblemumbles Do what I told you above, you need to find the sweet spot where it starts to etch the metal then raise the head about 3mm to get the dark image. Also you want the lowest Frequency your laser goes to make dark images. I have a 30W so my laser can do 30 KHz to 70KHz. The higher the frequency the lighter in color for non MOPA.
@@Angryhelder yeah i already try for 1 week with every parameter and power setting with my 50w and 50KHz and raise the focus, but the result is always not truly jetblack, it turns out greyish black. but thanks for the info. sorry for my bad english.
Hi Jeffery, Thanks for the video, it is very helpful. I am looking to do darkish marking stainless steel with a 30 watt fibre laser (it is MOPA) however I need it to be a durable mark. It is for a kitchenware product that will be used almost daily and be cleaned in a dishwasher. I don't mind if it fades a little over time but it must be durable enough to be distinguishable and not flake like MOPA laser annealing can over time. Do you have any ideas or know of a good resource for this? Cheers, Jason
Hi Jason - I don't have enough experience with long term durability of annealed black marks on stainless to give you a good answer. I'm curious though, how many washes does the mark stand up to until it is damaged? I may experiment with this...
Great video but I got quastion: so I got 2x fibers one 50w and other is 20w but 20w got 1-1000 freq. Where do I use this and for what? The 20w almost more powerful that 50w China model and 20 w is TurcMark sos laser.
Hey, i need some help! Wenn i open an file the grafic is shown correct in monitor, but the F1 button that shows the preview shows the logo rotated by 90 degrees and in mirror. When i rotate it in the software it will fit. so, do you know a solution...? Thanks a lot!
Hello! Excellent videos , Thank You very much!! Please can you maybe make a video of Hatch(0.01-0.05) vs SPEED(100-500mm/s) on Gray/SIlver Anodized aluminium at 50% power 40khz+ frequency?? I noticed a very big influence of HATCH on darkness of the mark. Tighter hatch giving brighter mark. I do not have access to Gray Anodized aluminium anymore, I used test pieces I had.... It would be a great help for those trying to get a dark mark on Gray anodized aluminium...
Hello Jeff, Could you direct me to a good place or group for Mopa lasers? I just purchased a Mopa Laser and would be great to find a place to ask some questions. Thanks and great videos!
Have you joined the wisely facebook group? There's a lot of good info there and several people have mopa lasers. If you haven't, check it out: facebook.com/groups/440091022989424/
Two ways: use the offset feature in ezcad and hatch the space between your oriignal line and your offset line - or - use the wobble feature. I made a short video on this a while ago.
Thank you for an EASY to understand explanation on frequency!
OMG...I don't know how much I've been looking for a well-explained articles or videos on this. Thank you!

Parameters (F3) >> Field Tab >> Galvo 1 = x
Swap that setting to the other galvo and it should be functional.
would this work on metal plated buckles?
Thanks Jeffery, your videos are very useful.
Could you please let me know what's the different between Frequency setting and Wobble Distance setting? I'm confused because they both change the density of the wobble circles.
i think that keeping the frequency constant, increasing the wobble distance must increases the speed, is that right?
Wobble is used to thicken a line. It will allow the laser to deviate from the 'on screen' path by an amount you set to gain thickness or coverage.
Frequency controls the number of pulses in a period of time - the higher this number is set, the less destructive each pulse will be.
Is this the same explanation for CW laser? I seen a CW laser where I am able to change the frequency (1Hz to 80kHz)
Never owned a cw laser so I don't know much about them.
@@jefferyj no worries, thanks for your reply!

Check out some of my other videos from the past. I've done a few on colors on stainless and titanium.
i too have 50W raycus fiber non MOPA, does frequency affecting the result too? because the company said no need to change the frequency because its not MOPA. i really need black smooth marking but never achive it, always looks goldish color. Please help me..
@@rumblemumbles Do what I told you above, you need to find the sweet spot where it starts to etch the metal then raise the head about 3mm to get the dark image. Also you want the lowest Frequency your laser goes to make dark images. I have a 30W so my laser can do 30 KHz to 70KHz. The higher the frequency the lighter in color for non MOPA.
@@Angryhelder yeah i already try for 1 week with every parameter and power setting with my 50w and 50KHz and raise the focus, but the result is always not truly jetblack, it turns out greyish black. but thanks for the info. sorry for my bad english.
Hi Jeffery, Thanks for the video, it is very helpful. I am looking to do darkish marking stainless steel with a 30 watt fibre laser (it is MOPA) however I need it to be a durable mark. It is for a kitchenware product that will be used almost daily and be cleaned in a dishwasher. I don't mind if it fades a little over time but it must be durable enough to be distinguishable and not flake like MOPA laser annealing can over time. Do you have any ideas or know of a good resource for this?
Cheers, Jason
Hi Jason - I don't have enough experience with long term durability of annealed black marks on stainless to give you a good answer. I'm curious though, how many washes does the mark stand up to until it is damaged? I may experiment with this...
Great video but I got quastion: so I got 2x fibers one 50w and other is 20w but 20w got 1-1000 freq. Where do I use this and for what?
The 20w almost more powerful that 50w China model and 20 w is TurcMark sos laser.
It probably be setting issues.
Hey, i need some help!
Wenn i open an file the grafic is shown correct in monitor, but the F1
button that shows the preview shows the logo rotated by 90 degrees and in mirror. When
i rotate it in the software it will fit. so, do you know a solution...?
Thanks a lot!

Hello! Excellent videos , Thank You very much!! Please can you maybe make a video of Hatch(0.01-0.05) vs SPEED(100-500mm/s) on Gray/SIlver Anodized aluminium at 50% power 40khz+ frequency?? I noticed a very big influence of HATCH on darkness of the mark. Tighter hatch giving brighter mark. I do not have access to Gray Anodized aluminium anymore, I used test pieces I had.... It would be a great help for those trying to get a dark mark on Gray anodized aluminium...
How could I get your file, could you help me please collect the file.
What is the pulse duration here?
very useful video
thank you for your time
Hello Jeff, Could you direct me to a good place or group for Mopa lasers? I just purchased a Mopa Laser and would be great to find a place to ask some questions. Thanks and great videos!
Have you joined the wisely facebook group? There's a lot of good info there and several people have mopa lasers. If you haven't, check it out: facebook.com/groups/440091022989424/
Thank you. Can you please also post this for brass?
Do you have a Mopa ? E or M laser
Hi Jeff, thanks for the video. I would like to ask how I can create a thick line (~1mm) on steel at a scan speed of 6-7 m/sec?
Two ways: use the offset feature in ezcad and hatch the space between your oriignal line and your offset line - or - use the wobble feature. I made a short video on this a while ago.
Please send me a link of the video of how to increase the line thickness in laser output.
So brilliant and helpful! Thank you!
Does someone has made the file for Minilase XL *.pse File? 🙂
what is the strength of this laser? I can't seem to achieve dark marks on stainless steel with the same settings with a 20w
20w, you should be able to do it. Double check your focus and pen settings.
@@jefferyj i just built a table like the end of this vid with adjusted hatch widths and that may have been the difference maker. Thanks!
very very very very very helpful
Can i ask ...you do that on fiber laser or mopa?
It is regular fiber.
Thank you so much! Your videos have been very helpful.
How do you engrave this in one step with different parameters?
You could set different pen settings for each part. You might find more info here: facebook.com/groups/4105345129538639/
How we can laser on gold colour in black stamp...
What parameters for brass?
Dude, was looking for that, thanks for sharing :)
