Just to add a little perspective for some of those leaving comments, I have a 20W MOPA and it is awesome, is it as powerful as a 100W MOPA? No of course not but these machines are all very powerful, capable and blazingly fast, if a job took 8 seconds on a 20W and only say 2 or 3 on a more powerful machine does that really matter? Max power is only 1 factor in any case, for example, engraving on plastic is likely to produce a dripping mess on most lasers that don't have the finer MOPA control options. The video was excellent and I think it represented the options very well, it just seems from the comments that many are looking at outright wattage on these machines as the be-all and end-all.

Great review. Thank you

[@BusterBeagle3D]

Thanks for watching!

[@I-LOVE-EARTH]

As always...another great video! You hinted on my biggest "complaint" about Fiber Lasers (I have one), the colors usually only look good at certain angles. If you look at other people's samples, they always show it at the best angle, something the colors look black. Even your great Mickey Mouse engraving would not look that colorful if it was hanging on a necklace. Even black doesn't look that great unless it's in the "perfect" angle.

[@BusterBeagle3D]

Honestly the settings that I used for the Mickey Mouse do hold up pretty good at angles. The black is something you can feel on the surface and same with the white and they really don't fade much at angle. The red and blue do go a little darker but still hold up at many angles. I have that file I created for Lightburn in the video description so if you have a MOPA give it a shot!

[@commarkerofficial]

Great job!!!! Thanks for sharing this video

[@BusterBeagle3D]

No worries. Thanks for the opportunity to test it out!

[@jimhamilton2680]

Thanks for the great review of the 60W. I work out of my house, so I'm wondering what are the power requirements of fiber lasers and are requirements different due to the wattage of the unit? In my work area I only have 110 available

[@BusterBeagle3D]

It just plugs into a regular 110V wall plug. It doesn’t need anything special.

[@jimhamilton2680]

Any idea as to the breaker size required?

[@shazam6274]

As an EE, I wonder if you have an opinion or have tried to make PCBs or thin copper elements (i.e. contacts or fingers)

[@BusterBeagle3D]

I haven't made them myself but there are many videos online of people using fiber lasers to my PCB boards.

[@Science3D]

Great video, Thanks. I just wonder : does 60 watt is too much if I want to create my own "PCB" (circuit boards) for electronic projects or does the 30 watt is enough or just barely enough ?

[@BusterBeagle3D]

I haven't made PCB boards myself but I want to say I have even seen those made with 20W machines. Just keep in mind that just because something is 60W doesn't mean it's always running at full power. While it's not exactly the same ,60W at 33.3% power should be very near a 20W at 100% power. I would think 30W would be just fine.

[@Science3D]

@@BusterBeagle3D thanks for the answer.

[@davidturner3749]

I've been looking for a different way to cut very small parts out of hardened stainless steel. .22mm thick. They are very small and detailed. So far I've had them made through chemical milling but that's getting too expensive. Just wondering if this laser could do the task?

[@newmonengineering]

Yes the laser can do the task, it may take a long time but it will eventually cut through. You can also do a wobble setting which essentially makes mini circles around the cut likes, this means the beam cuts a larger kerf but will help speed up a cut. When you say .22 do you mean 22 gauge or almost .25in? At .25in it's going to take a very long time to cut. It can still be done, but you may have to adjust the laser focal distance 2 or 4 times to complete and run the file many times. I'm not sure it is the best tool for .25in material. If you want to cut that thick cnc mill is probably still the best option to get it done in a reasonable time frame. 22gauge, that is much thinner and could be done on a laser but it will still take a substantial amount of time to complete. Just my 2 cents.

[@AllenCote4]

Thanks for a great review.2 Important questions for the nice 3D engraving job you did at 14:20: -How long did this one take? -In your experience would a 100W model cut this time in half?

[@BusterBeagle3D]

It was a little over 2 hours. Yes a stronger wattage means you can make it faster. It probably wouldn't be 100% faster, maybe something like 70-80%.

[@AllenCote4]

@@BusterBeagle3D Interesting that it took the same amount of time(or more) than the more detailed work you did at 13:19 . Now I know 20W version to save some bucks is a no-go, cheers!

[@BusterBeagle3D]

@@AllenCote4 The times can vary based on the detail of the engraving but it's almost backwards to what you would think would take longer. After the design is sculpted out the laser will skip over that area at a faster speed then the laser is engraving the parts it's still cutting out. This means that even with a lot of detail, as long as it's uncovered it will now skip it. With something like the Air Force coin there were lots of deep open space which meant that that laser was still moving at the cutting speed over those areas instead of faster skip speed. Hope that made sense.

[@alwatts9713]

I'm thinking too that a 100w model will also let you more easily use the larger 200 and 300 lens sizes since you'll have more power at your fingertips. Lower wattages won't do as well with the larger lenses. Correct me if I'm wrong on that.

[@BusterBeagle3D]

@@alwatts9713Technically yes, However I don't want to say they will do bad but you would work faster at 200mm lens with a 100W machine vs a 20W.

[@jamesdepner7833]

How long did the Air Force coin take to engrave?

[@BusterBeagle3D]

It took about 2 hours.

[@reidjensen569]

It looks like there is a lot of user requirements in order to get the laser dialed in with the two points that shows it is at the proper focus level, to me that seems like a turn off. Since you’re sharing your honest opinion, what is your honest take on this machine versus a commarker b4?

[@BusterBeagle3D]

My recent B4 is in a totally different ball park since it's a MOPA and 60W. I do like the smaller form factor of this machine however just from an ease of use standpoint. The B4 also has the longer cord for handheld use which I'll never do so it's honestly more of a hindrance. Both machine require at least a little tweaking to dial in perfectly but I did go into more of the setup with this machine since some of that info was lacking. The laser focus of this machine was a pretty easy and quick adjustment, the rest of that Lightburn setup was really just inputting the proper settings.

[@reidjensen569]

@@BusterBeagle3D I apologize, I should have clarified which B4 model, and I was referring to the smaller unit. Regardless, great videos of both machines with a honest review. Thank you for the reply.

[@endibobey]

Hi there, would it cut gold plates (0.5mm to 2mm thickness) without warping or damaging the material?

[@BusterBeagle3D]

I'm not sure. I haven't tried to cut gold myself, sorry.

[@endibobey]

@@BusterBeagle3D Np. Thanks.

[@remy9mm]

how many watts does a person need with ComMarker B4 JPT MOPA Fiber Laser Marking Machine for doing color on silver?

[@BusterBeagle3D]

I haven't tried colors on silver personally so I'm not 100% sure that is possible. For stainless steel and titanium even the 20W laser will give you color.

[@remy9mm]

Okie thank you @@BusterBeagle3D

[@timtrantow1979]

will these type of lasers do silver and gold.

[@xmdslipkfanx]

Yes. But avoid this brand. They’re filled with bugs and not properly calibrated.

[@BusterBeagle3D]

Yes you can do gold and silver with a machine like this.

[@coreyhol]

20 watt unit worth it to pick up ?

[@BusterBeagle3D]

It all depends on your needs but you can get a lot of stuff done with a 20W fiber laser. It might be slower but that doesn't mean it can't handle tons of jobs.

[@georgegeorge899]

There are some mopa laser videos that prove that it can engrave on wood or cardboard... Somehow the focus lasers were not in focus... Maybe you can play with the focus to engrave on other materials... 🤔 I'm still waiting for my laser to arrive... There are some scam sellers on eBay... I'm on my third attempt to buy one since October 🤦

[@BusterBeagle3D]

I have seen some videos where people either coat the wood or use some chemical mixture with titanium dioxide but it's really not recommended to use on wood. You are very likely to start a fire so it's really not recommended. A simple diode laser, even one with a simple galvo setup would be better suited for that.

Up to 300x300mm with an additional lense, but they only recommend this for a minimum of 50W. 110x110mm and 200x200mm lenses are included even with the 20W B4 variants.

That shield has to be a joke….. the glasses fit this wavelength at green. I don’t think that shield is doing anything

[@BusterBeagle3D]

Color does not determine the optical density protection of the shield. While I can't vouch for the lab testing on this particular shield you can find may orange safety googles in the 1064nm range.
