Hi. The brass was 1mm. If you look through our videos we have engraved black granite with great success on our CO2 laser. We have a 100 watt CO2 laser that my husband built from plans. If you do a search on YT for the 100 watt MOPA GA fiber laser you will see makers engraving stones from their back yards as well as granite. A 100 watt fiber laser will engrave gold jewelry, firearms, stainless steel, aluminum, etc. Check out Monport’s website for better details. We are just getting started and have some other projects in the queue. This is a weekend hobby for us, not a business, so we don’t do anything with it during the week. We post what we make and our fails so in that way we hope we can help others avoid our mistakes.
How thick is the brass that you cut? would air assist from not help with the heat problem? Does your laser not have a camera for alignment? can you do a test for me and use black marble/granite and show us how deep it engraves at 20, 30, 50 and 100% power and its respective speeds and how many passes to get a deep etch and the time it takes? I got a co2 laser but if I have to laser 200 Black marble/granite stones it will take me weeks to finish,. Im thinking for getting a fiber laser but im stuck between getting a bigger CO2 or a 300mm fiber. Im trying to think what will bring in more money more often. Another thing is Gold and Silver Rowmark, can you fiber laser it and cut it out on the fiber? Thanks
Also, if you go to our blog there is more detail about granite and stone/rocks on the Let’s Rock entry on October 15, 2023. The blog is rezolaserbuild@wordpress.com. Rezo is the name of the set of plans that were used to build our CO2 laser.
Hello again, I just wanted to thank you for telling us about the wobble. My husband gave your settings a try and the results as well as the effort were night and day. He was able to cut the 1mm brass in 25 passes and it literally fell out vs. having to press it out. You were so helpful and your advice was dead on. You seem to know a lot about this. Do you have any advice regarding how to achieve smoother edges? Ours are very sharp. My husband has used a Proxxon rotary tool to manually smooth out the edges but it’s tedious. Is there a clean up setting or “sanding/buffing” setting you have used with success that you’d be willing to share? Or, if you smooth your pieces manually, is there a method you recommend? Thank you again for your input. We appreciate your time. - Dana

First.
turn on wobble cutting
@@6942ggg okay, tell me more? What effect will that have on the cutting? Faster break through the metal? I’m here to learn! Thank you!
speed 100 power 90 freq 37 bidirectional hatch angle 0 line space 0.5 wobble dia 0.30 wobble dis 0.1
@@6942ggg We will try it!
depth map not height map
your cut speed is way to fast bro
your going to screw up your metal going over so many passes use wobble cutting
@@6942ggg indeed! The metal warped!
what a disaster
@@6942ggg never said it wasn’t. We are brand new to the fiber laser. Very different world working with metal. We know we have a lot to learn.
