ComMarker B4 Fiber Laser Engraving Machine 20W Review | Galvo Laser | Hand held

What do you think is the advantages of going with the 30w or 50w versions?

Thank you so much for the review on this machine I have a question if you were to choose between these machine MONPORT 30W Which you have review on which one were you choose? I do have enough space for that one but I don't know which one is better please help.

Another great video. Have you tried ceramic tile, or a laser marking spray to get a dark image on a steel tumbler?

Hello , is this machine can engrave or itching plexiglass plate with micro fine lines details image ? and what is the finest ( thinnest ) size of line can be engrave on plexiglass . and is the engraved line is it going to be solid line or half tone line ? Thank you

I bought one of these to mark date codes on parts. It’s my first experience with a laser and so far it has been great. I had a couple of questions on the suitability of what I was trying to do and the computer requirements for EZ Cad 2 and their support answered my emails in a day or two.

I really dislike it when review videos dont include at least a expected price range,

looking for Engraving Machine for my gun bossiness

Sorry I pick the option $2,599 and nothing happens I can’t see any link to buy now nor shopping cart, I’m sorry .

I went to the link to buy and is not available

Where can I get this one

I don’t know, this is looking good right now!

do I need to use a fume extractor ?

How high of a material / project can fit under the lens and still have it focus?

can you share your parameters?

Good explained it
I want this pls share the price details
I am at India

Would it be able to etch a PCB ?

What is the price of this engraver? Really interested

Rate ? How I got this ??

How deep can this go in aluminum? I see a lot of references that claim 20W can just etch aluminum and should use 30W, but that'll jump price 150-200% 😬

Test it cutting brass! Good to know if one can make brass parts similar to photoetched.

Very well done and informative. 👍

1064nm light is not UV (ultraviolet). It is actually IR (infrared) which is also invisible

Nice review Ryan 👍... This Laser Engraving machine only or cuter as will ? thanks Ryan

I got the same one a few days ago and the USB wouldn't work so I downloaded ezcad2 but it says can't find dongle do you know how to fix this

Great job as always Ryan! Great to see your channel growing. Super well deserved! ;)

What settings or line did you use for the rust removal?

nice review!

thank you for the review! there has been so little on this I was getting worried about backing it lol.

well.. i cant afford this.

Good name brand laser safety glasses are pretty cheap and should be considered a must with any laser.

Have a good holiday

I need one at work but because of the safety I need enclosed machine and so it costs 3x more.
