It has worked fine. No issues with stability or leveling.
Getting it to the right height is a bit of a hassle if you change material thickness frequently because in order to adjust it I have to remove the work piece and the honeycomb bed, turn the screw, add everything back to check if it's right, and if not, repeat the process until it's dialed in. Usually I am working with 3mm ply though so it's not very often I need to fiddle with it, and when I need to work on something bulky it's nice to be able to lift it without for added depth.
It will depend on your lenses and their corresponding focal length. Normally for cutting you want that focal point to hit halfway through the thickness of the material you are cutting. For etching slate I would put that focal length right at the surface.
The standard focal length for a k40, which is the laser I use, with the stock lenses is 50.8mm I believe.
I read somewhere that it takes around 150 hours of interaction to generate that bond of friendship between men.
That seems both a small number and a very daunting one given how many people live relative isolation today. Someone might say, join a club and make friends, but if that number is right that's an hour long weekly meetup for three years.
A friend of mine asked if I could make something for his sister who operates a local cat foster program. These follow the same design I used when I made these for my own sisters (previous post) only I did not make a frame for this one.
Here you can see the four layers of 3mm plywood I cut out on my laser cutter
I built this table for my sister-in-law back in 2016. She had just moved into her first home and asked if I would could maybe build a small farmhouse style table.
At this point I was relatively new to the hobby and had never built a proper piece of furniture that would function as a center piece for a room. She also did not have much money to spend so I came up with a plan to use some old barn wood I had scrounged up for the legs and construction lumber for the top.
There is a lot of internet hate out there for construction lumber projects, but I think if done right they can be an affordable option for folks. It's been 7 years now and this still sits in her dining room getting daily use. It has zero cupping, or wobble, and has remained as sturdy as the day I made it.
Being pine it is very soft wood and so it has its share of dings and scratches, but because it was made to look distressed from the beginning that just adds to it.
Is it both vector and raster engraving? Your description of "adaptive quality" sounds like that is what is happening. Can your software toggle off the vector engraving and leave only raster?
I use a CO2 laser, which has some different cutting properties than a diod laser, so I don't have much experience here, but I think for something with fine detail like that you'd be best to try grayscale
I had a gap in the wall from where an old monitor mount used to be attached so wanted to make something to cover it up.
The LEDs are controlled by an ESP8622 running WLED, monitor data from the PC comes from Hyperion software. It can be set to a constant color, dozens of set themes, or match the color output of whatever is on my monitor.
The microcontroller sits under the desk and receives constant power, it is the wired to a button on my desk to turn on/off power to the LEDs.

I was attempting to build a Kentucky stick chair, but accidentally bought too stiff of wire so had to pivot to a more rigid design. The end result is a not so comfortable folding chair. It works for me because I am tall and my legs clear the seat and touch the ground without issue. Not the case for my wife.
Here is what it was supposed to look like. Because the wire I used was too stiff I could not get the chair to sinch together so had to add spacers.
This chair is made from a couple cedar deck planks. They were first cut into strips
Strips cut to size for the back, middle,seat
Jig made to quickly make repeat holes for the hardware
I have a family member that is big into Weber charcoal grills, and each year he and all the other grilling enthusiasts from around the country get together for their annual meet up.
To commerate his last meet up I made him a set of slate coasters featuring Topper, the original logo for Weber grills.
Blank slate coasters purchased off Amazon. I think they come out to about $1 per coaster. The process is pretty simple. I put masking tape down on the bed of the laser then lightly etch a a few circles so that I can quickly center the blank coasters in my machine for batch etching.
You will notice some are darker than others, that is because I spray a light coat of poly which makes the etching pop. The darker ones already have been sprayed.
This was my first real dive into Arduino and multiple button mapping. It took a significant amount of trouble shooting and learning the software to get things to map to the computer action.
Prototype 1:Started this project before I had a laser cutter and had tried to just drill through acrylic. It didn't work well, but it held my buttons during testing

Still no laser cutter but I cut out using plywood worked much better for manually cutting out the holes
I had bought a big box of bulk Pokemon cards off of eBay and had been giving the kids a few each time they did their chores or as positive reinforcement when the did something good.
I wanted to find a way to make it more fun so came up with this prize wheel. Instead of just giving them two cards from the pile they get to spin the wheel and the corresponding prize. Usually just let's them look at a few cards and pick the one they want vs random getting one.
There were some "rare" cards too which they had a chance to win.
I have been a hobby woodworker for about a decade now, and this thing is by far the most fun I have in the shop. Unlike building a big piece of furniture that can take me weeks, I usually can come up with an idea and be assembling things within a few hours.
I am posting this for people wondering what you get when you order a $350 CO2 laser cutter off eBay. I purchased this 2 years ago and have had no issues. All of my woodworking project posts that involve a laser cutter are using this machine, although I have upgraded/modded the machine since purchase
K40 is name for this generic Chinese laser cutter platform. There are lots of sellers under lots of names, but they are all basically the same thing.
There are some American resellers, like Omtech that you can buys these machines from and they will offer upgrades and tech support.
Here was the original posting, doesn't look like this seller is around anymore
I am not really convinced our house plants need labeling, but my wife asked for these so I made them! Since COVID she has gotten really into house plants, and every room is packed now with greenery which is great!
These are super easy to make and only take a minute to cut out. I have also used acrylic to make outdoor vegetable garden identifiers.

Shipped from a warehouse in California so I didn't have to do any import stuff
Double boxed with unformed styrofoam
Inside stuffed with the "accessories" which were mostly tossed in the garbage, and some loose foam.
I had an open wall and a sheet of cheap 3/4inch plywood sitting around so I made a French cleat wall.
If you are not familiar with the system, the slats on the wall have the top edge cut at a 45 degree angle and the shelving/storage items have an opposite angle so they slide right into the grooves.

Made from 10 layers of 3mm Baltic Birch plywood. This was a gift for my mother who has two pugs.
All the layers made this a pretty tedious process, with lots of failed cuts that needed to be redone multiple times. The small bed size of my K40 didn't help
There are small holes on each layer that I fed fishing line through to help with alignment while gluing it all together.
