Thanks for watching!

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

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!

Well what if you need to engrave some steel tumblers... but they are on the moon?

@@tradtke101 I would assume from your question that you spend quite a lot of time on the moon, good point, you've got me there.

@@secobaairways4585 no no . If i was on the moon id be good with the weaker laser. I need the 100W so i can sit in my yard and write my name on the moon. Actually go outside and look up, i drew a dickutt on the apollo capsule

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

Any idea as to the breaker size required?

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.

@@BusterBeagle3D thanks for the answer.

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

I have not personally but I don't see any reason why you couldn't

The lens is not a consumable product so there should be no reason for ever replacing it. However if you want to get different focal distance lenses or if you happen to damage it somehow you can replace it and they are not overly expensive. I think around $50-$70.

It took about 2 hours.

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%.

@@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!

@@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.

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.

@@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.

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

@@BusterBeagle3D Np. Thanks.

Hello, we have lasers that meet your requirements. Do you need them?

@@Aisha-er5jx Yes, I do. Tell me more please.

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.

@@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.

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.

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.

Okie thank you @@BusterBeagle3D

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

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

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.

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.

Working area is based on the lens you use. 70x70mm all of the way up to 200X200mm

@@BusterBeagle3D the lense is extra? How much

@@swflscratcher5893 It's comes with the 100 and 200 already but if you want a 70 or 150 they are $74 on the website.

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.

@@Bllfrnd I have a 50W fiber

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.

@@BusterBeagle3Dyou could try to laser through it
