Wow, this is one of the best videos I've seen, thank you so much! I'm disabled and retired, and trying to learn more about fiber lasers and develop a business plan to start a small business. Which laser, the power and features are still being determined based on what I'd like to market. Videos like yours are great, to the point, and very informative. You have another new subscriber!!

Woohoo! Thank you so much! My first ever Super Thanks! I am going to take a screenshot and frame it 😁

[@Technosteve]

@@JTMakesIt Regarding cutting the super thin sheet metal, have you attempted to put the metal in a shallow container, where it is submerged about 0.25" of water? I was wondering if this would get you better resolution on the cut, less discoloration, and perhaps faster cutting without the warping?

[@JTMakesIt]

@@Technosteve that's a great idea! I never tried it. But I think the water might get dirty very quickly and it will hinder the cutting effect. Maybe just a bit of water underneath the plate would already dissipate enough heat.

Hi loving the videos. Can the machine be used for wooden and acrylic work, especially in the cutting aspects.

[@JTMakesIt]

Thanks :) Fiber lasers don't work on wood and they can only engrave acrylic. They can only cut metals mostly. If you want to cut and engrave wood, and dark acrylic watch this video: kzbin.info/www/bejne/bmHRoauCnrqJpaM

[@BrandonRobinson-m4l]

Great review! I'm looking at this laser for a few projects, one of them being 1-off PCB stencils. How did you find the experiment you did on the Stainless steel? Do you think this would be usable as a stencil?

[@JTMakesIt]

Yes it is totally usable for making stencils. You just need to find the best settings so you don't overheat the metal too much.

[@benjaminellison]

Great video, thank you! I’m trying to check with Commark but having some communication difficulties - does this have a separate AC-DC power supply? I’ll be moving back and forth between 220v & 110v countries and need to figure out if I can just get a spare PSU for the other voltage.

[@JTMakesIt]

Thanks for watching! Glad to help. Inside there is a separate power supply which has a red 110/220V selector switch on it, so you only need to flick the switch when moving abroad. No need for the second power supply.

[@user-yc2eh9ki9u]

Please could advice which is better for cutting name pendant jewelry gold and silver

[@JTMakesIt]

For cutting you want 60W or 100W MOPA. It will give the best results. 20W is not enough for cutting anything thicker than 0.2mm in practical sense.

The site has MOPA 20, 30, 60 and 100W. If I go with the 20, what will I be missing out on vs 60?

[@JTMakesIt]

Deep engraving performance, speed on deeper engravings and most of all you loose usable power with larger lenses. You can't make aggressive engravings(material removal) or engravings on more demanding materials on bigger lenses because you loose power density with larger lenses (laser spot becomes bigger and you don't have enough power to vaporize the material)

[@m22j-z3e]

@@JTMakesIt Thanks for the response. I am a novice laser engraver, and would do small projects and tumblers. I am trying to see if I should go for 60W fiber or get an xtool or laserpecker 5 with dual 20w fiber/diod. I would like to cut acrylic, but not primarily.

[@JTMakesIt]

@@m22j-z3e If you want to cut acrylic (but not transparent or white) too you need dual laser source (xtool F1 ultra). I have reviewed it too. I have reviewed a ton of laser engravers on my channel. You can watch my other videos to get a feel of what a certain type of machine can do. I also did a dedicated video on tumblers.

[@m22j-z3e]

@@JTMakesIt I don't have much space, I may go with the XTool Ultra or LaserPecker 5 for the dual laser, I don't like that it doesn't have air assist for burning wood. I guess 20W is plenty of power. I also can't justify spending 4K+ on something that has 1yr warranty. The ComMarker comes with 2 years.

@@m22j-z3e ComMarker is great too. In the video description you can find my discount code if you want to use it.

[@redman2751]

So I’m curious. I’d like one of these machines but it’s definitely expensive. I’m aware it’s cheap for what it is though but expensive for my needs/wants. What’s the learning curve to this though. Will it be similar to when I bought my first 3d printer. Learning the software, and limitations of the machine or will it be more difficult or easier then something like that. Just curious what your thoughts are on it.

[@JTMakesIt]

@@redman2751 hi, standard fiber laser has one parameter more (frequency). It takes some experimentation so you get used to what certain settings do. MOPA has a bigger learning curve than standard fiber since it has another parameter (pulse width). It takes even more experimentation to get a feel for the settings. But it is not difficult, it just takes more time. But at the end it is very rewarding and you can do a lot with it. The main difference from 3D printers is that laser engraving effect can be very material dependent and it takes some test engravings to dial the settings on new materials.

[@redman2751]

@@JTMakesItso maybe similar to testing feeds and speeds on a cnc mill? Once you have good references is it pretty easy to grab a known material and pretty accurately get a finished product once you’ve determined your settings previously?

[@JTMakesIt]

@@redman2751 yes correct. Once you have the setting dialed in it is just a matter of pressing the start button

@@JTMakesIt Sorry, I missed this information, yes, it's the non Mopa, however it's the one that it's available on my country, do you by chance know if there's too much difference?

[@JTMakesIt]

@@bootheprime MOPA offers more adjustability for more delicate materials and you can achieve more engraving effects. For deep engravings and "normal" stuff non MOPA is also very good. It depends on what you want to engrave

@@JTMakesIt Why not and how would the slate work with 7mm?

[@OrjanB]

This is very interesting for me. Instant subscriber. Would this work on flagstone or slate? Edit: How to know the wattage needed when buying a laser like this? Is there something the 60W can do that the 30W cannot? And what is the 100W needed for?

[@JTMakesIt]

Hi, thanks for subscribing! It works great on slat stone. Even better than diode lasers. The lower the power, the slower it will be at deep engraving and generally it can't engrave as deep as more powerful version. For 30W I would say it is good to enrave up to 0.5mm deep, the 60W works up to 1mm or even 1.5mm deep, I haven't had 100W yet to test what it can do. But a 100W could struggle with very delicate materials that require low power. 60W is a great balance overall, depending on what you want to engrave. You can watch my video of the 20W Commarker B4 (non MOPA) you will get a feel what can 20W do. kzbin.info/www/bejne/gqe4poiFg7unnqc

[@OrjanB]

@@JTMakesIt Thank you for replying to this. A followup question, would it be correct to assume that a 30W laser is capable at doing the same as a 60W laser just using more passes and more time?

[@JTMakesIt]

@@OrjanB yes, with an exception of very very deep engravings. And if you want to have a lens with bigger working area, more power is handy as otherwise beam gets less effective. Otherwise it can do the same things.

I am amazed by the works you've showned in your video but was asking myself "is that all possible with MOPA fiber?". The question came from the fact that there is also UV and CO2 lasers available for galvo scanning for various materials and i hear that MOPA fiber is only for metals. Looks like not:):)

amazing video, I would love to see you use this machine on sterling silver(Jewelry making), if you ever have the time, please do it.

[@JTMakesIt]

Have not tested it on silver yet, but fiber lasers work wonders on silver. It should be able to cut it easily and engrave deep or completely black.

[@aarongebrehiwot6391]

@@JTMakesIt what about deformation for thin sheets? I mostly deal with thin sheets of silver and gold(copper too) when making jewelry, one more question, how much of the silver or gold will evaporate on cutting? both silver and gold have a high melting point so will the laser just melt them so that they are retrievable or will they evaporate? thanks in advance, this has been bugging me for a while.

[@JTMakesIt]

@@aarongebrehiwot6391 The deformation can be avoided by adjusting the cutting parameters - like what I did when cutting stainless steel. Cutting silver will produce tiny dust particles that are theoretically retrievable. A lot of people use fiber lasers like this one just for making gold and silver jewelry. These are the best machines for this job.
