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.

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.

Maintenance for Redsail Co2 Laser Tube

Tuesday, January 6th, 2009

1)Be sure to keep the water running before starting the laser machine ;
Be sure to keep cool water filled in the tube and then turn on the power;
Please make sure the temperature below 30 degree.

Remark:
(1)Especially in summer, once the water temperature is high, please change the water in time or turn off the machine immediately. 
(2)In winter, be sure to avoid freezing up.
When the machine is off work, please keep the water out of the  Co2 laser tube completely, or, ice may cause the tube to break when starting it again.

PS: It is better to use soft water (distilled water or pure water)

2) When using water cooler, be sure to keep the water running at a speed of 2L-4L/minute. It will affect the working result if the tube cannot be cooled well and will shorten the life of tube.

3) Make clear distinctions about anode and cathode (usually outlet of the tube is cathode), so that it could be installed in correct position.

4) Be sure to protect the tube output port. Avoid port being polluted due to smoke and dust during working. Once it is dirty, please cleaned with alcohol slightly, or the tube power may be affected.

It is better to protect the laser tube connection with high-handed adhesive tape to longer the life of the tube.

5) Be sure to keep the laser power supply clean enough. Dust and smoke will affect the output power during the working.

6) When making alignment, the tube position may affect the working result. So we could move the tube and adjust the tube supporter to get a better position and get better working result accordingly.

7) When using the tube, be sure to avoid water furring the tube, or it may block the tube. Once it is furred up, please use 20% refined salt to clean it.

8). Being made of glass, the tube is easy to break, so when installing, please avoid being given force partly.

9) It is better not use high power all the while. Keeping high power will shorten the life of the tube. If it is necessary to use high power for a laser machine , please stop for a while about every 4 hours.

10) Usually, it could work for about 8 hours continually for a medium power. But be sure to keep the water under right temperature.

What is laser cutter?

Monday, January 5th, 2009
A Laser cutter is a machine that uses a laser to cut materials. The Laser Cutter works by making the laser enter through the side of the material that needs to be cut and shoots it through the axis of the beam. If a cut needs to be made and there are no edges near it, a small piercing is done before the cut. During a piercing, a high power concentrated pulse of laser beam slowly starts to make a hole, creating an edge to begin the laser cutting with.
Laser Cutter (sometimes is called laser cutting machine )Configurationslaser cutter is same as cnc router, when configuring laser cutter, there are three different configurations to choose from: moving material, hybrid, and the flying optics system. The difference among these three configurations is in the way that the laser beam moves above the material that is being cut. One common similarity that all of them do share though is that they all utilize the X and Y axis as the axis of motion, while the controller above is designated as the Z axis.
Moving materials configuration is when the material that is to be cut is stationed below a cutter head. The biggest strength about this configuration is consistency. As the laser is uniformly and steadily held above, the material can be cut quite steadily. The downside of this is that the material that is being cut (the workpiece) needs space to move around to be cut.
Hybrid laser cutting because of a cooperative work between the laser header above and the workpiece below. The table moves in one axis (often the X axis) while the cutter head moves in the opposite axis (usually the Y axis). This coalition allows a relatively good and stable constant beam delivery path length than other configurations like the flying optic configuration, while also having a simpler beam delivery system.
The flying optic configuration has a moving cutter head with a stationary workpiece. This configuration usually does not require material clamping. As the moving mass is fairly consistent, the cuts are quite clean. Also, this configuration is by far the fastest among others, as its acceleration and peak velocities are superior compared to the moving materials and the hybrid systems. When changing the length of the beam from near field to the far field, techniques such as collimation, adaptive optics, or constant beam length axis is used.
These processes are for the X Y systems, but the configurations are constant for machines with more than two axis, such as the five or six axis machines, which allows formed workpieces to be cut.
