I’ve received a new laser engraver, and it might be just the best one yet.
Awesome frame and design, a lot of safety features but best of all, incredible laser
power and precision.
Could this cut through 2cm of hard wood?
Well stick till the end to find out that and how to use a lot of other features such as
easy install of the roller axis for cylinder prints, control and print directly from your
smartphone, engrave huge designs, easy laser focus, cut wood, leather, acrylic and also
engrave over clear glass.
Check this video in case that you want to get the same product and I hope my review
will help you make a general idea.
So guys, let’s get started.
What’s up my friends, welcome back.
Today I have yet another laser engraver into my workshop so let’s check out the new ORTUR
Laser Master 3.
Let’s start with what you receive inside the box and that should be quite quick.
Basically, you get the frame made out of 5 metal parts.
These have a great design by the way.
Then you get the laser module.
Together with these you get a manual, wires, connectors and nuts, belts and some tools
together with some safety glasses.
Obviously, you also get a beefy power supply to go with the machine.
This supply is 24V.
That’s basically all you receive when you buy this machine.
Using the QR code you get some very easy instructions.
The manual is very complete with all the steps and with great illustrations.
Assembling this machine only took me a few minutes.
Is pretty straight forward.
Pass some belts, join the metal sides together, insert the moving axis and add the screws.
The pieces lock in very well so it will be a perfect square.
Finally connect the belts, which is also very easy.
e tip of the laser module and then place the unit in place and add all the wires just as
in the instructions manual.
Ans just like that, the machine is ready.
Connect power supply and in just a few minutes we have the machine ready to go.
The laser unit has a small foot and this is used to focus the laser spot.
Just extend the foot, unscrew the laser unit and start lowering it till you touch the surface
that you want to cut or engrave.
Connect it to a PC using the USB connector, run the needed app and there you go, we could
now engrave.
Before the test, let me tell you a few specs.
First of all, the engraving area is of 400 by 400 mm which is more than enough for me.
And second of all, the laser unit.
It is a dual laser module, basically it means it has two lasers inside, merged into one
spot.
It’s advertised to output 10W of true power and be able to cut through 30mm black acrylic
or 20mm of pine wood.
The best feature is probably the air assist tube.
It has a prepared nozzle and on the top we have an input for air assist.
Air assist is very important and could improve your cut a lot.
I don't have a compressor right now but if you have one, it would be easy to connect
and have a jet of air at the output of the nozzle.
I really like they went a lot more professional and got rid of those aluminum profiles and
made their own metal frame.
It is a lot easier to assemble, it assures you that the angles are perfectly squared
and it also has a way more professional look.
Since the entire machine and the moving axis is a lot lighter, it can move faster up to
20.000 mm per minute and that’s more than enough for me.
Is faster than other models that I have.The laser precision and focal spot is of 0.05
by 0.1mm so we can get better details.
It has WIFI, SD card and USB connection.
One of the best parts is that you could use this machine with a great app and we will
check that in a moment and print from the smartphone.
The App is actually pretty great.
Together with all that, it has some basic but very good safety features such as safety
lock, active position protection using the stepper motors as sensors, sloping position
protection, exposure duration detection and more.
And obviously, an emergency stop.Another thing I like is the easy use of a rotating axis.
You already have the connector output so you don’t need to change anything on the main
board.
Just plug the rotating axis part and flip the switch from linear to rotary and that’s
it.
In a few seconds you can engrave over cylinder parts.
Now let’s make some tests.
You could use light burn which is a paid software or LaserGRBL which is free.
Later we will also try out the smartphone app.
Download and install LaserGRBL.
Import a picture, select the size, power and speed.
For my test I’ve made a circle at 400mm per minute and 40% power.
It didn’t go through the 3mm plywood but that’s normal at 40% power.
I’ve place the power at 100% and lowered the speed at 300mm per minute.
This time it went right through without any problem and in just a few seconds.
And the cut is very precise.
So, I’ve increased the speed to 400mm per minute but this time it almost passed through
the 3mm plywood.
So best result with this material was at 300mm per minute at full power and only one loop.
It only took a few seconds to cut a 5cm diameter circle.
Then I tested with 5mm plywood.
At 300 mm per minute and 100% power it went right through.
The power and precision is amazing, the cut is very, very, fine.
I don’t have 10 mm plywood but I can place two of these on top of each other to get 10
mm.
I place it like this over two wood blocks so we can see when the laser is passing through.
As you can see, at the second loop, the laser was already passing to the other side at 300mm
per minute and 100% power.
Is amazing, in just a few seconds you could cut 10 mm plywood without any problems, and
I bet we could go even further.
I’ve made 3 loops just to be sure but anyway, I’m more than satisfied.
Also I can notice that the cut is more precise than with other lasers, it seems like the
laser dot is a lot smaller.
To test the limits let’s try it on this hard wood of 2cm, it should be interesting.
I’ve placed 20 loops to make sure.
Guys, this is amazing, at around 16 loops you can see the light below, meaning that
it passed through, and this is hard wood.
After it finished, as you can see, it almost cut through all of it, maybe with a few more
loops.
I cut the wood to see the depth.
And yes, we can see the line till the other side.
Maybe with some more powerful air assist it could be done.
But what I’m amazed about is how fine the line is.
That means the laser dot is very small which is a very good thing for precision.
And the line is very fine even on the bottom part.
Usually lasers create a cone shape, getting bigger and bigger as it goes downwards.
Let’s try other stuff, for example engraving.
I’ve made this Nikola Tesla picture to be engraved line by line.
I will use this wood circle.
I think it turned out great at 6 lines per mm.
Increasing the lines would take longer but maybe get better details.
Then I engraved this pattern from white to black at 5000mm per minute.
We get a decent contrast, right.
I’ve then tried at lower power and higher speed and as you can see the contrast is lower.
So you need to play with the settings and write down your results for future engravings.
Another cool part is the easy use of the roller axis.
You get the roller and just plug the stepper motor into the YRR connector.
Then just flip the switch to YRR and as you can see, instead of moving the Y axis, now
we have a rolling axis for engraving cylinder stuff.
I first made some test on this wood tube but I had a small problem.
In order to print at that height, I had to suspend the machine over some plastic parts
to get the clearance.
These are not steady so the machine moves a lot so the engraved designed was also moved
so I need a heavier support.
But if it waren’t for that, I could easily print over round parts.
Then I’ve pained with black paint a glass jar so it would absorb the laser heat.
Let the paint dry a few hours.
You could also use acrylic paint if you want.
Then I used the roller and engraved it over.
This process looks very cool, you can see the blue light all over the place.
Make sure you wear your safety glasses.
Anyway, after the process was finished, we cleaned the paint and we got this.
Amazing, I was able to engrave over clear glass.
This gives us so many possibilities.
And it was quite quick, around 1 minute or so.
As you can see, I’ve made this engraving two times, and the second time was at a higher
speed but it still turned out great.
And this is not dirt over the glass, is engraved into the glass.
Very nice.
I don’t have leather but I have this leather belt from a watch.
It was able to cut through with only one loop.
So, have in mind you can easily cut leather as well.
What can’t this engraver do?
I’ve tried to engrave a big picture with laser GRBL.
It was all going well but as you can see, at some point, the cable from the laser got
disconnected and I had to plug it back.
I have to place the wire better so it won’t get hung to the frame.
But without paying attention to the error, the design turned out ok in around 55 minutes,
and it is a big design and I went at only 5000mm per minute.
I’ve also made a small engraving over a metal sheet painted with black paint.
As with previous tests, this turned out great but I have to say, the details are better
than usual due to the smaller laser dot.
So guys, with this machine you can cut hard wood up to even 2cm with a bunch of loops.
But remember that it was able to cut through 10mm plywood without any problems, and maybe
even more.
10mm plywood is quite useful for making projects, it’s hard enough to create all sorts of
frames.
You can cut acrylic, leather, cork, plastic and rubber, you can engrave over cylinder
shapes with the roller mode very easily, you can engrave huge designs since it has a very
big engraving area and you can easily engrave over clear glass, that’s so cool.
And remember that is very easy to assemble and it also has a very cool app.
Download the app to your smartphone.
Is very easy to connect.
Once connected, the app is very well made, not like other attempts.
You can control the machine from here in real time.
You could also create g-codes from pictures and send that directly to the engraver from
your phone.
I finally have a decent engraver app that could be useful.
So guys, that’s pretty much it.
Parts I like, well, the frame and the entire design are awesome and the power is even more
than that.
I was quite amazed I was able to cut through that thickness.
I also love the laser precision and small spot.
I like the easy mode for the roller option , just plug in the wire and start engraving.
I also like the huge area and safety features.
One part I don’t like is that it doesn’t have any tall leg supports for printing taller
parts.
You always have to add something below, but is not that big of a problem.
You can always find something to put below, right?
I hope this video gives you an idea about this product in case you want to buy one.

Thanks again and see
you later guys.
