hello,
i am beginner of engraving. I used lightburn for wood and it was nice. now i have another project with metal but i dont know which settings i should do. i am trying 100%power with air assist and speed 200 and interval is 0.01. which settings you can advice me guys? also should i choose line or fill for this illustration?

i am also using metal engraving spray.
Itās usually some kind of spray that will create a molecular bond with the surface. Takes the right machine to actually engrave.
Doesnāt the manufacturer of the spray recommend a speed/power setting?
Which spray are you using (link)?
Use the preview to see what the expected results are. I like the look much better with fill.
oh i did not know that. i am really beginner of lightburn. where is that āpreviewā?

this product i bought to test before buy bigger one. but i told sth wrong:))) so sorry but i am not trying to engrave metal, i am trying to engrave silver. i dont have any problem to engrave metal or steel. i have problem about silver. do you have any idea about it?
Iām language impaired at that site. However it does look like itās really a co2 based type of bonding. Doubt this works well with diode lasersā¦ But donāt know for sure. Iāve use similar products, but they are for co2 lasers.
What works great with the co2, doesnāt really bond with my led lasers.
Iād ask the manufacturer about the specific application with your type of machine.
If you can engrave metal, then you are doing goodā¦ I canāt see why silver would be a problem unless youāre actually burning the anodizing off the other metalsā¦
I also donāt know your machine well enough about metal and the type of laser you have. Most lasers donāt work on metalā¦ thatās generally a fiber laser type.

sculpfun pro max 20w laser.

can you also tell me that my machine is co2 or diode?
yes, and only in 5 minutes. i wrote my name to steinless steel in 5 minutes without any sprey.and it was not marking. it was really engraving.
the difference of steel and silver: silver is amazing about heating conduction. you can fire right side of steel. right side will be more hot than left sides. but about silver. you can heat left side, but right side will be same degree like left side. maybe laser can not focus the heating on correct place because of that. i dont know really but i must to engrave 
Yours is a solid state diode laser. A co2 is a tube with mixed gases and usually requires a coolant. Most are dc excited, so they have a high voltage power supply to excite the tube enough to start/keep lasing.
There are two issues with metal, it is highly reflective to a lot of wavelengths (laser frequency) and itās a great heat sink. Reflecting most of the beam means the power is not on the work material, add to that any heat that gets there is diffused into the metal quickly. Some metals have a 98% reflectivity ā¦ 100W onto the surface, 2W into the material.
Generally led and co2 are for natural materials and fiber is for man made materials.
Yours appears to be a quad laser systemā¦ why above my price rangeā¦
This is the wavelength graphicā¦ Yours is a 450nM laserā¦ notice itās on one end and co2 is at the otherā¦ Also, most diode lasers are lower in frequency. Longer wavelength is a lower frequency.
Maybe someone else can give you a different perspective.

I dont know. but this one is the most strong hobby laser. I could not see more stronger.
I believe youā¦ they keep getting more output powerā¦
Good luck
Maybe have a look here: Settings guide - Diode Laser Wiki
Diode lasers are not the right tool for handling metals, though the 20W is already capable of engraving/marking some. Usually only stainless steel and no others. If metal engraving is your main job, check out fiber lasersā¦
thank you so much really. Do you have an idea how many watt fiber machine we need to engrave silver and gold? I am so sorry, i am just trying to help my father to find correct machine. I dont have an idea about this sector., but i have to help him. Thank you for your understanding.
Most of the low end fiber lasers run about 20W, they go up from there. As does the priceā¦
Iāve never seen a lower power oneā¦ However there is this laser from AtomStack that claims itās a fiber laser, it isnāt what I know as a fiber laserā¦ that may not mean much 
https://www.amazon.com/ATOMSTACK-M4-Precision-Positioning-Engraving/dp/B0B79XLNSW/
This is from their advertisement.
M4 fiber engraving marking machine can engrave metals and alloys, rare metals, metal oxides, ABS material, epoxy resin, Leather, wood (lacquered), ceramic (lacquered), stone, etc. ATTENTION: Light colored or transparent materials will be better engraved if they are painted/sprayed black with a marker before engraving!
Their āAttentionā statement, makes me wonder what they are doing.
This is what I consider a fiber laser, which I donāt see in the AtomStack. I donāt even see fiber in the AtomStack āblow apartā diagramā¦
Donāt forget you need to do it on strange shaped objects.
None of these are low costā¦
Hello friends. I found a 40watt laser atomstack r30. If I change motherboard box and laser of my sculpfun s30 pro max, it will work with work? I mean atomstack r30laser with atom stack mother board.
That is the atomstack r30 laser. It s written that it is working to engrave silver and gold.
