My first fiber laser- ComMarker B4

Like a kid at Christmas! Great video thanks for sharing looking forward to seeing new ideas of what it can do. Might buy one also

So, just as a safety note: You are vaporizing metal. Microparticles are getting into the air and that can easily enter your lungs. You may already have a setup for that, but if not, I highly recommend it for yourself and anyone that enters your shop. Especially if you have any loved ones using the space ever. Some element of a vacuum + filter to take that away is in my opinion a must for any laser type work. Many materials can be toxic if inhaled, and there is no amount of metal that is safe to be inhaled. Awesome work, good luck on your projects!

Very interesting machine.

Nice video, David. It must be fun to play with those lasers as you learn what they can do. Looking forward to what you do as you learn more - you seem to pick this stuff up fairly quickly. BTW - I had wondered what you do for a living ... never guessed Police. My FIL was a cop for 23 years. I like to watch OP Live on Friday and Saturday nights. Be safe out there - you have a dangerous job.

Really interesting video. I know nothing about fiber so this was well worth the watch. BTW, if you ever want to do something different, would be really cool to see you on the job with maybe a ride along video. Anyway, always. enjoy your vids bro! Thanks.

Your comment about not catching fire made me wonder what it would do with Magnesium. I know that it burns and can't be put out as easy, and using water makes it burn/flare up. Seen it on shop fires with air compressors. Great Video.

You probably already know this but laser glasses only work for certain ranges/outputs. Make sure you are wearing the correct lenses for the laser in use now that you have several different types. "Don't shoot your eye out." -Ralphie's mom

LightBurn is fantastic! But just an FYI for anyone who thinks about pirating LightBurn instead of paying for the very reasonable one time license fee: if you use a pirated copy of LightBurn, the software has secret code that will detected its not a legitimate copy and cause it to randomly burn the words "Lightburn is two developers, you are stealing our livelihood." onto a random area of your work piece ever so often! .... don't ask me how I know 😂

nice

To get a black mark on steel try taking your laser focus to a few mm above the surface

I've been thinking about taking the plunge on a fiber laser, and was looking at this one. Still on the fence on this one or another portable/split model.

Not to change the subject, was wondering if that laser tool box is available. Would love to do one on my x7 pro.

one thing I wonder; when doing something like the pow-container with high and low parts in the etch, the result seems to not mind the difference in depth, but I wonder if the focus is set to mid of high and low, if the etch is sharper? Yep the thing I would be second concerned about is putting my hand in the way while it is working.... (first is eye protection). I do have another question; eye protection, many people say that the glasses the mfg sends are not the best. Is there a way to verify quality of the eye ware?

Hello nice machine! have you tried to color engrave on silver?

Uhh Ohhhh I have always liked the idea of Fibre Laser, but until today have not seen one used from 0 hour of a beginner, I just wish it was in my budget, Psst wanna buy a Kidney ? Going cheap AU$4600

I'm thinking of getting a B4, and I'm wondering if stepping up to 30w would be worth the price increase. Any thoughts?

Looks like you are doing a crosshatch engrave on magazine.

ive burned wood but its tedious. glue aluminum foil to the wood and with the right settings will transfer the heat to the wood as a burning.

Enjoyed your review enough to pull the trigger and buy one (B4 30W). My main project for this machine is marking copper but so far I have had little success. Throughout this process I've been attempting to get some help from ComMarker product support but but this is not going well. Similar to Atezr product support, I get non-specific boneheaded answers to specific questions, repeated requests for stuff I've already sent them, 24 hour delays between responses, many things lost in English to Chinese translation, etc. etc. Have you had this problem? I'm trying to grow a business here and I'm afraid this tool isn't going to work for me. I'm assuming they sent your unit for free, have you used it to make anything?

Curious your thoughts on purchase several months later. My primary purpose would be for engraving tools such as wrenches, screwdrivers, hammers, etc. I have literally thousands of tools would like to engrave with good depth and resolution. I have also eyed a 30 watt unit, would like something capable of good speed, penetration, ease of use(is light burn most versatile?), and decent size work area. Secondary purpose would be something I can engrave things like coffee mugs, laptops, Ipad. What say you?
