I see that you already used another laser for mold making. Very cool. That pricetag though. Ooof.
@BusterBeagle3D6 ай бұрын
Yeah they are definitely not cheap but it’s pretty amazing what you can do with them. If you use it in business for things like tumblers, flasks, jewelry, or challenge coins they will pay for themselves over time but it’s an investment for sure.

I use matte clear cote for my slates, i think it looks more natural on a stone slate than glossy clear cote.
@BusterBeagle3D4 ай бұрын
I agree. It’s just what I had handy but I think matte would have been better.

Nice looking unit, seems to do well. I'm a prototype developer for industry and want to know how well does this laser "do on cutting through" flat ps of various types of metals and plastics? What would you say is the max thickness it can burn through for various basic metals such as Steel, Stainless, Aluminum, Copper, Acrylics etc. Thanks, great demo!
@BusterBeagle3D7 ай бұрын
Honestly I'm not sure about the max distance per material. I only ever went down for 350 passes. The deepest I got in brass was about 1.63mm. My guess is you can definitely go deeper but I haven't yet. You could also always lower the laser down a half turn or so and keep going deeper if that is what you are trying to do.

These machines can cut thin metals but they are not ideal for that purpose. For like aluminum foil yes easy, but if you want like 1mm or more it will take a long time and you may have to dial focus as it cuts. If that is your goal a small cnc mill is better for cutting metal. I have both, and for cutting I use the mill, it's way faster. Just my experience.

@@newmonengineering These lasers are way over-priced for what you get and their functionality. Unless you have a specific and profitable niche, definitely choose something else with more varied capabilities and flexibility.

Thank you for this great video! I wonder if this fibre laser engraver at 20W can be used to cut at 0.2 mm to 0.3 mm thick aluminium alloy shim?

It should be able to, it might take more passes then a more powerful machine but it should be able to do it.

I have used fiber lasers to make molds in Aluminum for my Buster Beagle 3D MK3 injection molding machine in the past. It works well but does take some planning and tests to get it right.

What are your basic Jarvis settings? I have never been able to create even a decent photo.
@BusterBeagle3D6 ай бұрын
I just clicked on Jarvis and then used the settings you can see in the video. Some of the image was adjusted ivy right clicking on it and choosing adjust image. Then I pretty much used the white on black preset in that window with a few adjustments to the contrast and gamma until I was happy with the preview it shows in the window on the right.

won't the z-depth vary anyway due to the the angular distance to the galvos?
@BusterBeagle3D7 ай бұрын
Somewhat, yes. However when you compound that with either an out of focus or curved surface it exaggerates it.

Can it drill holes in .25mm thick sheet metal less than .2mm in diameter?
@BusterBeagle3D7 ай бұрын
While I didn't use it to drill holes my guess would be with enough passes you should be able to.

How does this compare to the ComMaker B4?
@BusterBeagle3D6 ай бұрын
If you are talking about the 20W B4 they are pretty comparable, at least with the version of the 20W that I had. I think the newer 20W B4 might be in the same larger form factor as my B4 60W MOPA. Also the B4 can be handheld so if that’s important to you then go with that. Personally I would rather not have the longer hand held cord.

@BusterBeagle3DАй бұрын
There is a learning curve to all lasers. Fiber lasers are no exception to this rule. Figuring out settings comes with lots of testing as well as libraries from other users that have already done the testing as good starting points.

Why would I pay $2000 for something that could literally blind me during its normal function? They should definitely do SOMETHING, even if it's just a thick cardboard box
@BusterBeagle3D5 ай бұрын
Most laser engravers until recently came with no enclosure whatsoever. My first laser a few years ago didn't even have a shield on it at all, you simply had to rely on the glasses that came with the machine. This machine also comes with laser glasses as well. While it won't blind you , you still want to shore it up as much as possible to fill those top gaps. Again any enclosure is better then no enclosure.
