I have a CNC laser engraver with 1m x 1m bed and I decided to build an enclosure for it.
Here is the CNC: https://fun.balashova.com/2020/11/1m-x-1m-cnc/
And here is how the project started:

First Welding Project
I have got a flux wire welder and this is my first project:
Bananas are just for scale.
I could of re-weld and re-polish all the imperfections, and do some finish, but maybe next time.
My takeaways about the welder. It is not a hand-help 3D printer or a glue gun, even though it spits the wire. You cannot (easily) 3D-print with it. Also, it is much easier to deal with thick material than with a thin one. It makes holes in thin metal sheets and pipes like a woodpecker. Also, you cannot safely weld most of the metal parts you see around because they are either galvanized or stainless of non-ferrous. Bummer!

Why?
Because Halloween is coming…
And because I had 3 scrap lights and some scrap plywood…

Laser Engraving on Cylinders
I have got a R-axis drive as a birthday gift.
It is just plug-and-play with GRBL controller.
And it is also adjustable

80 neje laser
This is not Neje and not 80w. This is shady “40w” laser from Aliexpress.
Guess why did I polish off the corners like that?

How large is your spinner
Spinner size is limited by hand size. You cannot make it more than 7 bearing large, or you would not be able to spin it. Or could you?
Well, I can spin my 15-bearings spinner:

Trash Can Repair
I have a fancy dual-bin automated electric trash can.
I almost like it (well, if it would also be Alexa-controlled… sounds like a new project idea…)
Anyways, it has 2 bins – for trash and for recycle.
And it has a fancy trash bag holder. Which has an interesting design but way too flimsy and does not stay in place.
So I decided to reinforce it.
Here is my design:
And here is the cutout:

Spoon Failure
Hey, I made another wooden spoon!
Cool!
Wait a minute, why there is word “failure” in the name of this post?

Is there a chance for fast laser engraving?
Laser engraving is pretty cool.
However, it has obstacles.
The biggest obstacle is engineering stubbornness.
Let’s take a look how getting mentally stuck inside the box holds us back.
Laser engraving with common GRBL controller is known to be sloooow.
Some folks claim that STM32 controllers are faster.
So I have got one of those and did a bench test.
Here is the board.
Spoiler: result was unexpected, but you can probably guess that by my bitterness in the introduction.
