This Thing Means Business! - The ComMarker B4 60W MOPA Fiber Laser

[@hamps856]

Great job David, excellent presentation and as always very informative. These things are exponentially more powerful and with greater utility.

Another great video! Crazy how it can also remove rust.

[@Spencebehere73]

Great video. Am currently researching heavily for a business and your opinion and thoughts are valid and great to hear

[@JustinAlexanderBell]

9:35 You can easily cut through 1mm aluminum with this machine, enable a small wobble with a cleanup pass inbetween scans.

[@Neo7CNC]

Thanks. Can you share your exact settings?

[@CruiseMonkeyGames]

Oh, the visual puns ... so groan worthy! 😂 Great demonstration, definitely on the wish list.

13:12 If that is an oxide it obviously became too hot. I think it needs to reach above 4-500C to start appreciably oxidizing. What was the pulse timing/speed/power?

[@rowepjr]

Thanks for informative video. Looking forward to future videos on rotary and MOPA frequency engraving. I dream of having a machine like this but I can not afford. I will have to get my small business moving to get the money.

My opinion, MOPA is not a great beginning machine. Get a hugh power without MOPA. You can still get colors adjusting speed and frequency. MOPA is cool, but it adds another conplication to set the other pulse length. Instead of one frequency you have 2 to adjust for every project. In all honesty except in some edge cases, its nit worth the hassel to setup all of these changing numbers for each type of material. Does it do more? Sure. Is that MORE worth the extra price? And How often will you actually play with it enough to use the MORE part? For me, especially if you are just getting into it, its extra that you will not really use that much and its also adds a lot to test runs for learning the machine that makes the entire process more difficult. I have played with both, but if it was my first machine I would buy as high power as I could afford and leave MOPA for later after you know what your doing. Power is more important than adding a second parameter in 99% of the actual jobs you will take on.

Such as amazing review. Thanks for sharing ❤

[@DPSS808]

Is this significantly different than the more expensive cloudray or the higher cost split version of this laser?

[@tumdedum]

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

[@CalyoWiselyLaser]

nice video

[@dublinvids]

Apart from portability, is there any advantage to a machine like this over the bigger Chinese machines that usually come in cheaper with the same overall hardware? Im researching at the moment before buying but dint see the value in something like this over, as an example, a Haotian or OMG laser with same specs.

[@b99eu]

Did you get any answer to this question or can you answer it now?

[@bentheredonethat9296]

I cut 1/8" thick steel with my 60w MOPA and my 50w

[@the_luminary]

really？ How long did it take? and many passes？

[@amritrandhawa8717]

Where we can buy steel sheets in canada ?? Help!!

[@EZ_shop]

I wqas really excited about it until you mentioned the price. Ouch! Ciao, Marco.

[@Didisixty]

I think a Mopa M7 has 10 kHz to 4.000 kHz Pulse Frequency, not only 40 kHz

[@BigPoppaR]

Instead of doing a fill in the whole shape, do a wobble on the line.

[@wantafastz28]

Pricey but cool

[@TheMichiganShow]

0.00039 = 4/10??
