Plz recommend a good brand and proper watt laser engraving machine for granite engraving grave stone pictures.

[@TheFalconJetDriver]

I learned something new! A new way to pronounce Granit not granight!🤯🛫

[@JAYTHEGREAT355]

Where did you biy that grinite plTe

[@centralseac]

Great video. What about engraving Obsidium stone, I have tonnes of it here?

[@MellowpineLasers]

Thank you. I have never engraved obsidian yet, will post a video if I do it.

[@patberry3388]

So I am using an Epilog 60 watt laser. I want to engrave the Welcome granite sign. Would I use a speed of 2100 mm/second? What would be your recommendation?
Thanks.

[@sashgorev]

60W optical or suply power?It's very serious diference.All setting that are mentioned are for optical power.

[@sashgorev]

My experience - milky white granite with medium size crystals directly without painting, 600mm/m 100% of 30W diode=2mm deep engraving. I do not advise anyone to cause such a load on the optical system of their laser. Regards.

[@razaaligulfam6011]

I want to buy a laser engraving machine for black marble granite which brad and watts you will recommend for me.

[@MellowpineLasers]

For a good balance between the quality and budget, I would suggest
a 10W diode laser. The one I used in the video is Ortur LM3, but you can also explore other brands like Two Trees TS2 or xTool D1 pro.
If you plan to setup a business primarily focusing on engraving granite, then a CO2 laser would be a better choice as it produces better results with faster engraving speed.

Oil paint work instead matt finish?

[@MellowpineLasers]

I haven't tried yet. It might work.

[@gagerendon5099]

What website do you use to make your design?

[@MellowpineLasers]

I primarily prefer using Photoshop, Illustrator, and LightBurn's inbuilt design tools for my projects. However, Imag-r is an online tool that I occasionally use for image preparation when significant modifications are not required.

[@centralseac]

Can one use Tempura paint instead of spray paint?

[@Wigmore72]

Yes, you can.

[@MellowpineLasers]

Yes, it should work

[@jusufuswaray8339]

Those this method work on black tile

[@MellowpineLasers]

You do not need a transfer medium to engrave black tile.

[@gerrymouzakitis3966]

White paint with titanium dioxide may work better.

[@MellowpineLasers]

I have talked about using white paint with titanium dioxide in my Laser Engraving Ceramic Tile video, and it produces excellent results. Haven't tried it on granite though. I think it can be a good idea for engraving on white or other light shades of granite.

[@jarreddunlap7065]

Dude, i have an xtool d1 pro 20w and im not getting anywhere near those speeds. And ive cleaned and painted and everything.....i just dont get it.

[@MellowpineLasers]

The possible reason can be the difference in the type of granite. Like I mentioned in the video, I also found varying results for different batches of granite. While one needed 100% power for good engraving, other started to show good results at just 30% power. Which is why it is always best to perform a test run when you get a new piece of granite to work on.

[@jarreddunlap7065]

@@MellowpineLasers the painted granite worked a lot better... Plus I realized that my protective lens was cracked, so once that's replaced I'll get cracking again

[@wsparry1066]

Hi very nice video,,but is it possible to talk a bit slower for those just starting out in lasering please,,👍

[@chammockutube]

Consider CZcams playback at 0.75X speed. I playback most instructional videos at 1.5X speed but his speech cadence is faster that most, so I dialed it back to 1.0X.

[@MellowpineLasers]

Thanks for pointing that out. Will try to improve it in my future videos. 😊
