*"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.
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.
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 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.
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 JefferyJ, excellent explanation. Would it be possible to see the parameters published for certain "colors" such as RED, YELLOW, BLUE, on stainless steel?
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
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.
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 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
Hi Jeff, I just bought a nice used 30 watt fiber laser. It worked great at the seller's house, because of course he KNEW what all of the settings do. Well, I loaded EZCad2 onto my laptop, and got as far as the laser drawing the DXF file with red light, but I am NOT burning or etching. Can you do a video on how a complete green behind the ears NEWBIE laser owner can get set up and burning? I can draw DXF files using my plasma table software, so I do not need to know about drawing with EZCad2 quite yet. But I want to know what I am doing WRONG, that I cannot burn an image into a black anodized blank business card. I have subscribed, so I will be watching with great interest!
You have to dial in your focal point. I was having the same issues getting stuff to burn. The process I used as a newbie was to move the laser up or down by 1mm at a time and trying to mark. Once it starts to burn, keep going and pay attention to the sound of it marking. Once you hit the loudest point, that's it.
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 ! 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
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.
Anyone know how to record the prefect circle? I use the circle tool but when I record it I don't have any prefect. I need urgent help, since I spent a lot of money on my machine and I still haven't been able to use it. :(
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.
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, 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...
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
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?
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?
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.
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.
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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yQflgf5ylJg.html and ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eywQfOA7kic.html Some of those settings may be useful to you. If your laser is more powerful, tweak the power and speed settings.
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/
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.
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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kmxDePbHHOk.html
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!
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 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/
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?
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.
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?
