Laser Cutter/Engraver

[Mcgyver]

Remove living room winow and furniture. Place in middle of room. Put window back in place.

Sounds good. Then my wife will be asking on some other forum "how do you get rid of a body?"

Dan, a shed would be great, but I'm the middle of the "6". For a heated, powered shed? Permits, inspectors, drawings, fees, neighbours complaining, committee of adjustment ..... naw

I wondered about xtools. As I know nothing about lasers or what a Galvo head is I suspect like many, i'd probably buy into the hype and purchase one. Luckily I don't have room at the moment.

Xtool, Gweike.... all those are sub par both in quality of components and especially custom support. If you want to deal with a mainstream vendor then buy from someone like CloudRay, at the very least as they have been established long enough to be there if you have a problem. My next laser will come from Haotian or BWM Tech.

Thanks for the reply @Mcgyver!
It is perhaps starting to look as 1watt./per 0.001inch +/- cutting steel might be a figuring point to start at power wise for a laser. I am sure there is more to it than that, type of laser, galvo heads and such likely factor into it too.
But only more info would be “make” things clearer, or maybe not. Manufacturer claims are “interesting”, real users are the best.
Lasers cut flesh well, smaller pieces are easier to hide, or get to the grinder—- a neighbour was known to say “don’t pis% me off, I have a grinder and hungry dog”, hmmm, also had pigs.

Hey, now do not get this wrong, was just thinking about @Mcgyver saying” wife would be looking on forum,— getting rid of body’s”
The old saying “ learn to use the tools you have”, a laser. Course, here, it’s learn to use the tools others convinced you to get. Hey, I only got so much learning for each day! AND, today is going to be a slooow one.
I am also starting to think that some members may have stocks in lumber/building supplies, “oh sure you can/should/have/buy one of these here.” There is no room in my shop — no problem’oh just add a bit here and it will fit! And, oh hey, well looky here, this will fit too.

@1018Machine , how many times would you have to lower the head for .25 inch engraving? Or what is accurate? depth of cut/metal removal when engraving? I realize focus/ size/diameter of beam changes things. A small/tight?/focused beam needs less wattage to do the same thing? and gives better/higher definition.

I must have missed this question, sorry!

For deep engraving (with accurately cut side returns) and (based on my 30 Watt fiber laser) it's wise to lower the galvo head every 2mm otherwise the sides start to taper due to the lens going out of focus.

Thanks ,@1018Machine, another piece in the puzzle.
As to the shed @Mcgyver, if it’s got to be inspected, could be interesting. I have just lately found out if I have more than 5 people tranportion vehicles in my shop, the rules change. Venting, and some other things. The “weird” thing is 5 mopeds, or 5 very large buses, 5 transports, etc. But 5 — 747 planes and a moped, no way, that’s 6, the “danger rating” etc. changes from F2 to F1, with a list of changes that need to be made. Don’t matter if broke and don’t work! “Hey dude, there’s like 9 bikes, sh##t no, there’s another bike, and a car in here!
Yes, I am in the mire of some changes, would say middle, but don’t think I am that far yet! LOL, MAYBE.
Pictures, @JustaDB knows the mess I keep and anyway still working on Annoyed picture phone to “new” fruit loops pad.

Pictures, @JustaDB knows the mess I keep...

Mess? Last time I was there, bare concrete was still in evidence. Pretty sure the Model A didn't cover that all up.

There is a bunch of bare concrete, just not much in the shop, anyway no more then when you were there @JustaDB. Same old, not catching up on the projects. LOL

Laser etching/engraving is highly fascinating and I have a technical question(s): My son is acquiring gem faceting equipment for the purpose of making gaming dice for Dungeons & Dragons gaming. These dice have 20 facets(+) and will require marking on each facet and would be made from mineral/stone material such as marble, hematite, onyx, & other types of minerals (not sure what all myself but many are costly). He thought using a machine that cuts masking material to paste on the facet and then sand or glass bead blasting the surface would work. This method hasn't been tested but the cost would be quite inexpensive.
However, we both thought that laser engraving would be far superior to the blasting idea but cost is a factor; and will it work? My concern is that to mark the facet of the finished product after the material expense and the lengthy production time, would the blasting technique be of a quality worthy of the desired end result of a high end product. Some D&D aficionados pay anywhere from several hundred to several thousand dollars for specialized dice.
I quickly looked at some of the laser machines discussed and after the considerations budget-wise, would the Atomstack A20 Pro (at $1900 Canadian $) be a decent choice to accomplish this task? This cost is really stretching the budget.
I would also like to use it in my metalworking projects for various things as well.
Thanks to all in advance for your wise & knowledgeable advise!
