Laser engraver & cutter reviews

Saturday, October 29th, 2011

“CO2 (carbon dioxide) laser engravers have been around many years. The reason I like CO2 laser engravers and the primarily reason that ……. evaluates this technology is because CO2 laser engravers can help museums and archaeologists render images from ancient civilizations.” We read this part from a magazine. Its good start and explanation for laser engraver and laser cutters.

 Redsail is also developing 3D scanning and 3D printing (3D rapid prototyping) for similar reasons: these technologies are ideal for preserving cultural heritage. And all these technologies, can also help people to make busdines, make money, alive.

How to decide, and distinguish among so many brands laser cutters and laser engravers?

We saw many people, may magazine say that how cheap, how bad that China lasers are; but China still sells lots of lasers, and is still going to develop biger and bigger, more and more; that is because, the people in the world, need chinese lasers.

It is the truth that some other countries like USA or Japan that invented this kind of machine, but that is not fair to call “chinese copy ” just because we are later than some other people/.

We make it , because the world need it.

Redsail is working well in this line, and will be better in this road too. If you see how many pcs machinese we sold and how poplular we are when we show in the machine in many markets. You will find, something that is cheap, might not be that bad.

We are improving ourselves, we are trying to give more support to customers; We are responsible for our machine and customer. We suppose that is the most important thing.

Don’t laugh at the followers because followers one day may catch up you; don’t call those copy just because you made it first.

Review for cnc router and laser cutter

Wednesday, June 8th, 2011

Redsail is the manufacturer for both cnc router and laser cutter. Most customers are using the two types of machine for one job, while what is the same feature and what is the difference between the two types machine?

Same feature:

1, they can do both engraving and cutting.

2, they both need water chiller or air chiller

3, they both need to make good file from software, and sometimes they are using same software

Difference:

1, the biggest difference is , after laser cutting, no need for polishing, but you have to work with a polish machine after cnc router working.

2, laser cutter is working with laser tube and cnc router is working with blade, obviously

3, Mostly, cnc router can cut thicker than common Co2 laser machine. But still need polishing.

Laser helps you to make a dream

Thursday, May 19th, 2011

I talked to a customer Simon yesterday about Redsail laser cutter. He bought our laser machine 4 years ago. At that time he bought a laser model C120 and now we upgrated this model as CM1290.

He told me Redsail laser helps him to realize the dream–make a small shop, make some craft, do some business, and support a family.

This is how a laser made: with this laser, we can make a adversting company, cutting some acrylic sheet, cutting differnet design, you can even make a small factory. It just needs your idea and little money.

Where you can find this kind of laser?

Laser problem 1–why does the laser only move seconds then stop?

Saturday, August 7th, 2010

sometimes when you operate Redsail laser engraver or laser cutter, you may face problems as below:

Yesterday it worked perfectly, but today, laser machine only moves several steps, then it stops. Why?

If you check carefully of the machine, next to the control panel, there is a E-STOP—its emergency stop. Means, when you face problem, press this button, the machine will stop immediately to keep operator safe.

But after push this button, if you do not pull it out, laser engraver or laser cutter will keep under this condition. Then when you restart the machine, it will only move few steps then stops.

So, dont worry, pull the button out.

Laser Machine Specification Reference Settings

Friday, May 14th, 2010

Laser machine can do lots of materials and jobs, like acrylic, plastic, leather, wood, and many others. But when customer get a laser engraving machine or a laser cutter, they dont know what power I should use for cutting a piece of wood? what speed should I use to engrave on glass?

To get perfect result needs more time practice and experience. We need to try different settings to test on different materials to know what setting is the perfect one. But here we can show you some settings for Redsail laser machine. But this setting is only for reference, you still need practice more.

                                      Engrave                                    Cut 
  M300:  
Material      Current     Speed    scan gap        Thickness   Current   Speed
Wood           9MA       14-16        0-2                       (3mm)       1A            1  
Leather          7MA       14-16       0-2                                       9MA         3
Jeans              8MA       14-16      0-2                                       9MA         3
Acrylic          8MA       14-16       0-2                     (2/3mm)       1A          1
Double layer   9MA        14-16      0-2                   (1.5mm)       1A          1 

M300 bitmap engrave: Usually speed is between 12-16, power is between5MA-1A, and
scan gap is 2 or 3. It cannot cut with a bitmap file.      

 M500.M700.M900 (vector graph)

Marble                          50%       400       0.025               
 
M500.M700.M900 (Bitmap)
        Usually speed is between 300-400, power is between 50%-70%, and scan gap
between 0.05-0.09, it cannot cut with a bitmap file

Laser Cutting Machine 80W (C120, C150, X1201)  
                                                Cut
   Material                    Power               Speed
 Acrylic (5mm)                85%                 3      
              (8mm)                 90%                2   
             (10mm)               95%                 1.5 
Wood board (5mm) soft one   80%          8   
  Double layer (1.5mm)         70%        9    
 
 
Laser Cutting Machine 100w(C120+, C150+)
  Material                             Power       Speed
Acrylic (5mm)                     90%                5    
             (8mm)                      90%                 3    
            (10mm)                     90%                 2
Wood (5mm) soft one         80%             10
Double layer (1.5mm)         70%             10

All the settings above are for Reference. Since long time’s work, power of tube
will decrease, and machine parts will also be wearing away during use. So it needs some
changes on the setting according to situation. The above is the reference when we do
settings using that material. So settings always needs changes when met different
requirements from different customers, such as different thickness and stiffness of
different materials, and others.
