Frequently Asked Questions

As long as you know how to design jobs in graphic software, it just takes a few hours for you to become a master of laser machine.

You just need to do some tests to know what speed and power is good for different materials. Since we’ve provided some of the

parameter library, it will save you more time.

You can watch the guiding videos from our website to learn how to use the machine in advance too.

No, our laser machine can do both cutting and engraving very well.

You just need one machine for both kinds of jobs.

yes, every machine will wear. However, you don’t have to worry about that. The machine will be working normally at least 2-5 years.

After that, you may need to change the parts. And all the parts can be replaced. We will charge at a fair price.

Higher watt tube with more power can cut thicker materials, or we can say, for cutting same material, higher watt tube can achieve faster speed.

However, theoretically speaking, the lower watt tube with smaller laser power, which is better for engraving. Usually we suggest 40-80 for engraving, 100-130w for cutting.

Yes, we have maximum 130watt laser power for your choice.

the standard model is 10CM diameter, for the detail, please check our website:

https://www.thunderlaserthai.com/features/rotary-axis-2.html

The standard focus lens is 2”; there is 4″ for your choice.

Shorter focus lens will have smaller final beam diameter. That’s why it is better for engraving good quality photos.

And longer focus lens is better for cutting thicker materials.

For a laser with less than 80W and clean engraving jobs I would recommend the Silicon-Mirrors because they have the best

reflectivity (>99%).

For a laser who is doing very dirty work (cutting wood 8 hours a day) or working with aggressive chemicals I would recommend the

Molybdenum-Mirror. The reflection coating (there is no coating, the Molybdenum is just polished) is very resistant and can get cleaned

very easily. Even if the reflectivity is only at 98.5%, the Mo-Mirror is almost unbreakable.

Yes. We have

Open flap protection switch, the laser will stop working if you open the front cover. Water protection, Laser will stop working if the water cooling system is not working normal. Emergency stop, Turn off the machine immediately when there’s accident happen. Alarm Lamp, show the work state and tell when the job is done. Heat Alarm detector, the laser machine will warming with loudly voice if cutting material catch fire.

There’s an exhaust fan comes with the machine.

Yes, Red dot laser pointer is standard feature of all Nova machines.

See below detail: https://www.thunderlaserthai.com/features/red-dot-pointer-for-nova-system.html

The normal color of the laser beam is purple while working. When a tube is dying, the color will become white.

Usually, the power of the tube is decided by two parameters:

1. The length of the tube, the longer the tube is the more powerful.

2. The diameter of the tube, the bigger the tube is the more powerful.

No, we don’t suggested that.

A more powerful supply may damage the laser tube.

No need.

There are two ways to adjust the focus.

1) You can adjust the laser head manually

https://www.thunderlaserthai.com/how-to-use-your-laser-machine/how-to-manual-adjust-focus-distance.html

2) Use a motorized up/down table (auto focus)

https://www.thunderlaserthai.com/features/auto-focus-for-nova-system.html

Yes, the co2 tube is controlled by the power supply. And the power supply is controlled by the controller. And you can set the power

rating easily in the software.

High resolution Attachment will make the laser dot smaller, thus you can have much better engraving quality.it is used to engrave

extremely high quality photos. For detail, please see

https://www.thunderlaserthai.com/features/high-resolution-laser-head.html

For the engraving distance,

With standard 2″ laser head, the distance between laser head and material is 5mm-6.5mm.

If cutting thick material and 6mm distance does not give a good result, you can try adjusting the distance down to about 5mm. For

details, please contact with our tech person.

For cutting some thick materials, it is correct.

But when engraving on some materials, it’s better to use less powerful air pressure.

The normal life tube of a laser tube is about 2500-4000 hours according to how you use it.

Yes, footstand of desktop laser machine is an option. We will take it apart for shipping and you can set it up with screw later on.

Here’s the size information of Nova machine:

https://www.thunderlaserthai.com/desktop-laser-cutter

Usually it’s suggested to leave about 200mm space for the backside to install the exhaust pipe.

For the other sides, need about 100mm for each, but when you need to replace the parts of the machine, please move it out to a wide place.

The USB connection is on the right side of the machine, please have a look at the pic.

Yes, we have pass-through door design for our machine:

https://www.thunderlaserthai.com/how-to-use-your-machine/pass-through-door-design.html

You have to replace a new tube when it’s no longer working.

It’s not cost-efficient to recharging a co2 glass tube.

Usually we will pack it well and it’s seldom out of alignment,

Once it happens, we have video and lesson to guiding you how to align the laser beam:

https://www.youtube.com/watch?v=pw8Ro2vEEzY

If the beam is a small round dot, then it is perfect,

but in fact, most of the beam are close to round dot.

If you just realign the parts without reading our technical lesson or guiding video,

https://youtu.be/pw8Ro2vEEzY

It’s unsafe indeed even you wear laser safety glasses,

However, if you realign them by following our lesson and video step by step,

It’s not so dangerous,

And to make it safer, you can wear a pair of laser safety glasses,

Please note the most important thing is: familiar with the process of lesson and video.

No unsafe materials, and yes, they can be disposed of safety.

According to our customers’ feedback, life for the belts should be at least 3-5year.

When you find it is loose, you can adjust it by reading our user manual and watch guiding video:

https://www.youtube.com/watch?v=izI9HMzA0ds

https://www.youtube.com/watch?v=yRpCJAmwRw8

Yes, machine will get dirty after using for a period time,

Then you should clean and maintain it frequently.

For how to clean the machine and make maintenance,

Please read our user manual from page 47-56.

For cutting thick material (usually more than 10mm),

4″ lens is good for getting a more straight/smooth edge, but it does not mean you can cut more depth.

https://www.thunderlaserthai.com/features/4-laser-head.html

For exhausting the air outside,

standard length for the hoses is about 6m

is it ok for you?

if not, can you please tell me how long do you need?

I think we can offer special hoses to you,

for outputting the air,

it’s depend on your material,

if you use the laser for cutting wood/acrylic/leather/fabric, etc.,

it’s ok, no dangerous, but some or less smell I think.

and material like PVC/Vinyl contains chlorine are not suggested to cut with laser.

(its fume dangerous for human health and will corrode the machine.)

Max cutting thickness for acrylic：

40watt：10mm

60watt：13mm

80watt：18mm

100watt: 20mm

130watt: 25mm

Yes, our laser engrave 3D, like relief.

See below video:

https://www.thunderlaserthai.com/what-laser-cutter-can-create/3d-laser-engraving.html

No, for cutting metal, you will need at least 200watt laser.

We only focus on cutting non-metals at present.

However, by using a thermark spray. Our laser can also engrave on metals.

Yes, please download from below link directly

https://www.thunderlaserthai.com/laser-download

Yes, we can cut POM. Please tell us the thickness, we will recommend you a well machine.

For the workable materials, please learn the details from our website:

https://www.thunderlaserthai.com/materials

Please do not cut any material containing chlorine like PVC, Vinyl, etc. and other toxic material.

when heated releases chlorine gas.

This gas is toxic and poses a health risk as well as being very corrosive and harmful to your laser.

Yes, please check attachment picture.

Yes, normally cast acrylic is better than extruding acrylic for laser processing.

We didn’t test for engraving photos on metal with Thermark before,

and according to our experience, we think it should be not so good,

as you know metal become black after engrave with laser,

for engraving word, logo and simple pattern, it’s good to see it clear,

however, for engraving photos, I am afraid it’s hard to get a gray scale photo .

Yes, Anodized Aluminum is the best material for engraving photos.

and Color Anodized Aluminum is the best among the Anodized Aluminum sheets.

then Acrylic, ABS is also very good if you have a good quality ABS,

(ABS is a kind of plastic, some ABS will be bend after heat by laser).

No, our laser(co2 laser) can only engrave on surface of material/glass/crystal,

https://www.thunderlaserthai.com/sample-photo/all-photo.html

Yes, you can do more than one cut, but usually it’s not suggested to cut twice. Most of the time, one cut will get the best cutting quality.

The material we paste on glass is just a kind of common tissue paper,

since it help us to get a more smooth surface, (no so much rag)

it’s ok, you really needn’t worry about the paper, you just need to make it wet,

and then paste on the surface of glass you want to engrave.

for Thermark, yeah, it’s useful for engraving on metal,

and after you get the laser job down, you can tear the Thermark off,

(there’re 3 types of Thermark, you can visit their website if you like to learn more)

then you can get a clear pattern/words on metal.

10-15mm
