Great job David. As usual, very informative. 10 years ago I paid $15-k for a 40 Watt Universal Laser that this machine blows out of the water. And, I'm sure they will just get better!!
Thank you for doing this video. It is very useful and well done. I just ordered the B4 30w MOPA. How did you come up with the various settings you used to start with each type of material?
Thanks for the review ! One thing that isn't perfectly clear for me, regarding the maximum depth it can cut. Can't you just repeat the same job over and over to reach .3 , .6 , .9 etc... depth of cut ? Why is there a "maximum" ? Thanks !
I'm not sure all the reasons for the depth of cut listing but one for sure is the fact that as you engrave deeper and deeper into the material, you are effectively losing your focus of the laser which diminishes it's effect on the material being engraved. Thanks for the great question.
@@Neo7CNC Thanks for the response ! Good point, a slightly de-focused 20W laser probably loses to much power, while a 30 or 50W, even slightly out of focus may still have enough juice to cut further. From what I could see in various videos, the time necessary to remove material gets very unpractical (more than 15 minutes to cut a tiny circle through 1mm of steel with a 20W) and besides that, the part gets very hot, and the quality of the cut suffers as well. So it is, technically speaking, a practical limit, not a "hard" limit ... you could stay next to the machine for hours, cooling the part down, refocusing the laser, wearing out your diode etc ... if you really reeeaaally have to, this one time :D Otherwise it's just not worth it.
The "advertised" depth is a nominal figure and if you were to *slightly* tweak the focus a bit lower, OR not, making more passes/more depth will result. For a depth of say 1 to 2 mm, the unit is certainly not going to be out of focus that much to prevent a deeper deeper burn.... Just test yourself and discover the results....
Fuck yeah dude. I make project videos on a different app called Snapchat, but I’m starting to get into the phase where around 16K subscribers start thinking how do I approach companies for review units? Did they seek you out? Did you have to make yourself known in some type of group?
@@Neo7CNC awesome thank you. I really like the machine from what I've seen, but I saw some people saying commarker support is awful. What are your thoughts on this?
Hi, I just received the Commarker B4. I upgraded Lightburn to the Galvo version. I can't get Lightburn to recognize the laser. The USB connection shows up in device manager in Windows. there does not seem to be a device file as with a diode laser. I could not find a video on getting Lightburn to connect. If you have a link to a good video I would appreciate it. Thanks.
The USB flashdrive had some corrupted files. I was getting error messages from Windows about the drive. I downloaded the files from their website. It's working fine. Thank you for the your help!@@Neo7CNC

Great video. Very useful video, I think after your review I'm going to pull the trigger and buy this one but the 30W.
buy mopa
@@atntaltdyou own a mopa?
This unit worth the $$ ? any problems?

Hi can this machine laser engrave slate or granite or both for portraits?
wonderful video sir
does this have 0.01mm spot ? sir
it does.
@@rusticfox4283 that is working accuracy and spot size thats why i m confused, thanks for reply

Does it work with Mac?
I tested the B4 with a software called Lightburn and it does work with Mac.

Make sure you installed the Lightburn Galvo driver. I believe there's a section in the manual that covers what to do if the wrong driver is installed.
The USB flashdrive had some corrupted files. I was getting error messages from Windows about the drive. I downloaded the files from their website. It's working fine. Thank you for the your help!@@Neo7CNC
Goes deeper than .3mm But does require an adjustment down while Engraving Lol.. its will Only do .3mm/per focus setup
