r/Laserengraving

Hi I'm looking at buying a second hand

Refox Fiber laser model number LM-80B 6watt 110/220v.

However I cant seem to find this model online and I'm wondering if this will let me engrave metals to any significant depth. everything I find on it says this is is for removing the glass back from iphones, but "could" be used for other things. I know typically fiber lasers need about 20 w lasers to do this. Can someone with experience on this give me some guidance on if this will work for my art needs?

I am completely fed up of turning down jobs for laser engraving glass pieces.

Over the last year we've let go more than 6,000€ worth of glass engraving jobs because for some reason I cannot get my 5W UV laser to replicate what everybody and their dog are doing with theirs.

We've spent a significant amount of hours (and I mean hundreds of hours) of actual job output with plastics, marking metal, wood and plywood. HOWEVER

We cannot get to mark glass. The support guys tell us to try this and that parameters, but all we get to do is not repeatable. We waste 2 glasses to dial in, get one done, and the following one is already having shy and faded areas which results in another testing glass. Basically we have to throw away 1 for each one done.

Again, for other materials, we nail it, we've got to the point of almost zero wasted material,but glass is a complete nightmare for us.

Today we've tested settings recommended by support:

s:150, i: 0.04mm, q1, f50

Other settings from users in the community:

s:300, i 0.03mm, q1, f40

our best settings are currently:

s:80 i 0.006 q1 f33

However, this easily results in cracks.

I would really appreciate suggestions. I'm considering switching to the CO2 we have for glass. It may result in lower quality finish, but at least we can accept orders.

I bought a 22w falcon2, and want to recreate a product I've seen online, but i can't find what they probably used.

It's black over metals, like, copper, brass, tin

A whole black sheet, with the metal being "cleaned" but the terms I'm using are finding other things, like how to put black on copper.

It's too intricate to be vinyl.

Is it patine? Paint? Can a blue diode clean patine off?

So I've been running a small online shop since last fall, mostly custom wood signs, keychains, coasters, that kind of thing. Didn't expect it to actually take off but here we are.

The first few months were kind of a mess tbh. I went through a phase where I thought a cheap diode cutter would be fine for occasional orders. Then the orders weren't occasional anymore. I was re-running jobs because of inconsistent results, manually tweaking settings for every material batch, staying up late trying to get 40 pieces out for a weekend market.

Ended up switching to the xTool P3 around month two which helped a lot with throughput. Still had to figure out pricing, turnaround times, managing custom requests. The machine side got easier but running an actual shop is a whole other thing.

If I were starting over I'd probably think harder about what volume I was actually planning for before buying any equipment. Underbuying and upgrading mid-stride is kind of annoying.

So I just ordered my first laser engraver. I use my wood lathe to turn bowls.

The question. Does the engraver only work on a perfectly flat surface or can it work on a partially curved surface.

I bought it to engrave my name on the bottom which is flat but I'm just wondering if I could get a bit creative.

So our home has a nice, decorative brick mailbox enclosure. Set into the brick on one side (so that it is visible to passing traffic) is smooth cement rectangle where the previous owner had their last name engraved in cursive. I have tried to block it with plants in the past, but I'd like to get rid of the engraving. It seems like it could be "filled in" with a putty of some kind and painted over. It is currently painted white. Any suggestion on how to best tackle this job? Thanks!

I purchased a GWEIKE G2 20W Fiber Laser Engraver for metal nfc card engraving. The cards are about .84mm thick.

I watched some videos on calibrating it etc but wondering if anyone has already done it for this and has correct settings to help me.

I am now understanding I overlooked this lol and that there’s more steps to this than I thought 😂😂

So over the weekend our beloved dog died, and we are having her cremated. I plan to find a quiet spot on our property to bury the ashes and I would like to engrave a flat headstone for her. I can't seem to find a reasonably priced considerate option. I see like $20 ones on Amazon but they don't come blank or large headstones for hundreds of dollars. I am just looking for like a 6X12 inch flat polished stone, maybe granite or marble that I could engrave. Thank you if you have any suggestion
