Well I made my first post yesterday and already got in trouble.... seems it was considered a want ad..:confused: Sorry about that guys, didn't mean to get started on the wrong foot here.

Anyway I have been looking at laser engravers till I'm cross eyed and my head is spinning.......

I have looked at Epilog and Universal lasers but the initial outlay is just more than I want to spend for an untested market, I have looked at a number of the Chinese lasers, FSL, DigiCarver, Boss, Rabbit, and a list of others as long as your arm.

Anyway I guess I just need a little feed back from users of the various machines and their experiences with them to help me in my decision process.

I have some ideas that I hope would be marketable but would prefer to test first before I make a significant investment into equipment.

Thank's for putting up with another new guy.
Best regards to all.

William

Welcome to the forum William, no worries about your first post. It happens all the time and by long time members as well.

Can you tell us a little more about what size products you are looking at making, what materials, quantities, etc? Those things can help us help you. Is it most engraving? Mostly cutting, a combination of 50/50 of each? Also, what part of the country are you located in? That might help, as someone close by you might be able to reach out and help, privately.

Hello Scott.

The material I will be using is driftwood with a prepped area for the engraving.
Size will be variable but no larger than 10x18 ish. The actuall engraving area will vary depending on the natural contours of the piece.
I am on the Oregon coast so I have lots of material readily available to work with.
The work will require all engraving with no cutting.

I am very new to this (the laser aspects) even though I have been thinking about these projects and possibilities for quite a while.

Thank you for the feed back.

Hmm did my reply to his first post get deleted also???? I asked all those questions in my post to him. Whats up with that.
Anyway as far as machines go stay away from FSL. I think you'll find that if your going the Chinese route most people here will steer you towards a Rabbit. Their well built machines with top notch USA support right in Ohio. Ray has everything you'll ever need to take care of his machines.( I have one:D) Boss might be ok but we don't have a lot of feedback on them yet.
I think your idea is pretty good but not sure what the market is for something like that. I'm sure they would sell but how many at what price point would need to be tested I guess. I don't know how driftwood will engrave I'm sure some will be awesome and some maybe not , I think it would depend on the species of the wood .

William, I would suggest you first outsource the work. Sure this gives you less profit, but it'll let you test your market without a major investment. Depending on who you outsource to, you may learn a lot too.

Lookup Gary Hair on here, I think it's in Oregon as well. Maybe he can help you.

If you are looking at feedback on specific machines...well I can help with one.

See my sig for the specific ebay printer. I have been told its actually a shenhui laser. It doesn't say that anywhere on it so I can't confirm but it really looks like it and everything matches up perfectly.

My experience has been mostly a positive one with the machine. Nothing noteworthy has gone wrong with it. More user error than machine error. Its been able to do most of what I thought I wanted to do. I simply can't afford a box that can etch (really etch) metal.

I have added LED strip lighting (ebay, comes in self adhesive spools 191211931325). I added a honeycomb bed (again, ebay 151358120115). And I used my 3D printer to make a laser crosshair but you don't need that (but its nice!). All told, I have spent less than $75 on addons since I got the laser approximately a year ago.

Its served me well. Its easy to clean. Big enough to do the projects I have. Small enough to fit through a basement door. Cheap enough to make it affordable to start with. Powerful enough to cut most sheet stock and etch most non-metal products. Does fine with CerMark paints and Rowline plastics. Easy to use. Decent quality output.

The software is fair at best. Don't rely on it for daily bang. Get Corel Draw to do your designs in and ship it out to the RDworls that came with the laser to actually generate the gcode to the laser.

Like any new tool, there is a learning curve. How steep it is depends on your temperament and tech savvy.

Clear concise and to the point. Nice review of your machine.

Thank you for the great review Mike.
Info like that is a valuable help in making my decision.

Mike do you have a budget in mind? Most of us on here are cost concious to various degrees, but keep in mind you also get what you for when setting your budget. Also do you have a shop or is this a home garage setup? Any samples you can post of what you're wanting to do on driftwood? Will help people on here better determine what type of machine you might need if we can get additional details.

Here is an example of what I have in mind to do.
The image on the left is the kind of raw material I would be looking for, I would choose the area to be engraved, smooth and prep the area then do the engraving....
The image on the right is along the lines of what I would like to do with the unique pieces of driftwood.
I have given thought to how a router may come into the process in all of this as well.

One issue you might run into is the curve. That fish looks like it really has a step curve it's engraved around. When a laser goes out of focus it looses power quickly. Have you thought of how you will handle that or are you just going to do the flat pieces? How hard is that drift wood in comparison to something like maple?

That particular example is not exactly what I would do.... I would prep the engraving area to be "flat" so there would be no focal issues... It was just an example of the concept.

As to the piece on the left I would probably prep the areas circled for the engraving.

I would also agree with Tim, outsourcing at first to get an Idea of what the laser can do and what kind of market you have is a good idea and the least expensive way to test the waters.

I took that advice and.......
I have found a shop about an hour away from me that is getting me some quotes. Being only an hour away I could gather up the materials and images on a thumb drive and just take this to their shop....
I found another shop that would do this for a $15 set up and a dollar a minute laser time but there would be shipping the material back and forth involved with that shop.

William keep us posted as to how this venture works out for you. We'd like to see some pictures of a finished piece when you get them back.

I will do that. It will be a bit before things get started but it's-a-commin........
Getting through all the setup stage at this point, I think I will be going with the co. that is an hour away, I can go in and talk with them as well as get things fine tuned.
The proprietor seems knowledgeable and they were very helpful during our initial phone conversations.

I have also found a source for a laser engraver that is less than 3 hours away from me. The owner was very helpful and the prices were very fair for the equipment... He sells engravers and CNC routers.

Hi I would suggest you get someone to do some samples as suggested above but I would also suggest you learn to do the art work yourself (if you cant do it all ready) in that way if you decide to but a laser you will have much less to learn

good luck with your project Frank

Already on that road....... Thank you for you input here, all is appreciated.

Welcome William. Great comments above from some people with way more laser engraving experience than I have, but I will add my thoughts in case they might be of some use. First thing that comes to mind is that if the driftwood products are 95% of what you plan to make, then the really fine-scale beam quality and positional accuracy difference that exist between western lasers and Chinese systems will likely not make any difference in the final appearance of your product. The spot size burned into the driftwood will likely be sufficiently large compared to the beam and accuracy differences and it will not require an enormous power density to get a good burn. That still leaves the quality of the software and support differences between western and Chinese systems so it seems that you should weigh that against your budget and your skills/temperament as Mike A. mentioned. Many people on here run Chinese systems and do great work with them.

The other thing I would suggest is that you carefully consider your z-height needs--both in terms of total z-travel of the table and max z-distance below the lens when the table is fully lowered. Some of the lower-end systems may have less space and travel in z than you will need with odd-sized non-flat driftwood. Best of luck to you.

If you plan on engraving on anything but perfectly flat surfaces, you should look into getting a longer focal length lens and compensating for the power loss with a higher power laser.
I engrave boxes full of parts on not flat surfaces for one of my customers using a 4" lens, 80 W rabbit laser set at 325 mm/sec and 20% power

How much of a tinker are you? My first chinese laser was one of those cheap 40 watt ones ($400), and while it was finicky it was a good way to get my feet wet on the chinese lasers. It could engrave and cut 1/8" material with not problem. Large image it did not handle well, but vectors cutting and smaller engraves worked great on it. Though I have heard some people getting them and not working so well. So it's a risk.

As a matter of fact I'd still have it if I had not out grown in, and gone to a Redsail x700. which is my first choice. It has been very reliable, and rock solid. Support as been great. And while it's not a speed demon on engraving if you are not doing a lot large engravings it's a good buy. After hearing all the problems with other lasers here, and having worked with other chinese brands, I can honestly say that when I am ready I will be buying another redsail machine.
