I have a sculpfun Icube 10w
I am engraving metal tags on the same settings and just seemed to have lost all power.
What is going on with these?
Give us some details to work with…
Material,
Coating,
Speed,
Power,
Passes,
UFO passing over,
Etc…
Sorry
Speed 200
Power 70
They are just metal steal keyrings - not overy reflective, have dont some in the past with no issue.
first one came out great then the second one was really bad, now the cards i was doing is not coming out at all.
i say my laser has lost 90% of its power.
Ohh i also replaced the lens, that didnt help, seems every time i try to engrave something its getting worse and worse…
If I understand correctly, you’re saying it’s not working on other materials either and you haven’t made any changes to settings that worked previously?
It’s possible that the beam reflected off the metal back into the laser and caused damage.
How would you prevent this? It says it’s meant for metal engraving…
There is nothing about it in their documentation…
I don’t know if that’s what happened, only a guess, but I have heard of it happening. You can remove the bottom plate and turn it on it’s side and point it at a wall a few feet away. With your safety glasses on, turn on the laser at low power and see what the beam looks like. I believe it should be 2 well defined rectangles.
The only way to prevent it as far as I know is to have the reflective item at a slight angle so that the reflection doesn’t go directly back up into the laser head. It wouldn’t take much of an angle to prevent this. Certainly not enough to mess up the focus on something this small.
I’m sure there are LOTS of things not in the documentation.

I have sent it back and asked for a refund from Amazon.
I’m looking to either buy the same again and just not do any metal or a different laser which I’m guessing if that was the issue would be the same thing? Or is there a specific laser more suited to it?
Also is there any kind of film or paint I can put over metal to maybe protect the laser?
Like I said, I don’t know that this is what happened, it’s just a guess.
If metal is what you primarily want to engrave, then a fiber laser is what you need. A diode laser is not meant for metal. It can somewhat mark stainless steel, but not engrave it.
There is marking spray. “Cermark” is one brand that will allow you to mark metal, but that is not a true engrave. I don’t totally understand how it works, but it somehow fuses with the metal when lasered.
It appears so, kind of. I have not seen that delivery type. It must be a UK thing that the aerosol isn’t allowed so you have to mix your own with alcohol. In the US it comes in an aerosol can.
Thank you.
Will that also help protect the laser itself on reflective metal?
I’m not 100% sure. I would think so, since it leaves a dark mark where you lase. It should reduce reflectivity if not totally eliminate it.
Hello,
Im trying to engrave some black keyrings but the the underline colour isnt very bright. any thing that can do white instead of black?
Seems like you have two posts going on with the same issue. Why are you asking the same questions twice on two different posts?
