Laser Cutter TroubleShooting

There are three cases. 1. Two sides of the working table are not of the same height. Turn off the whole machine power, manually pull one of the belts of Z axis so as to adjust the up and down of the working table height of this side and calibrate the level in this way. Shown as below: 2. If it’s one of the four corners that is of different height from the other three corners, use method 2. As shown above, by adjusting these screws you can fine adjusting the support frame of the knife table so as to calibrate height of one corner. 3. If neither of above two methods can solve the problem, please use method 3. But it’s much more difficult. Please handle it carefully. 1. Loosen the screws of the fixed module. The belt will be loose accordingly. 2. Rotate the lead screws to calibrate the table height of this corner. (PS: rotate it clockwise, table in this corner will go up; turn it anticlockwise, table will go down) 3. Working table of this corner will go up or down when...

Some point of the same piece of materials cannot be cut through, why? This problem is mainly caused by following three reasons: The cutting material is bent (not flat) or uneven density. The working table is not level Laser beam is not vertical after being focused by lens.  If the material is not flat, please use magnets to fix the material. The working table itself is not level. Large height error causes different focal distances and this result in bad cutting result. Please check whether height of four corners is the same.  Please refer to the document of “How to calibrate the working table to level” if needed. Laser beam is not vertical after being focused by lens. Please check whether the laser beam is all vertical to the working table’s center and four corners. If yes, please continue to check step two.  If not all vertical, please adjust the laser beam path (directly adjust the third reflective mirror). Please refer to below ...

Following reasons cause the failure of laser working (has no laser beam) 1. Cooling system problem (includes water chiller) 2. Laser power supply (optical coupled isolator) or Laser tube 3. Wiring or Controller 1. If there shows “water protection errors, work pauses” on the control panel. 1) Pease check interfaces of water flow(ALARM OUTLET), see whether it’s loose or unconnected. 2) Pease check if the water circulation channel was blocked or not. 3) Pease try to replace the water pump of the water chiller because of maybe the water pressure was not enough. 2. If it’s not about water protection problem. Please check the laser power supply. Press the “Test” button (2) of laser power supply. Check if the laser tube will emit laser or not. (Before that, please unplug the green port (1) shown as below picture) Press Test button, check if the laser tube will emit laser beam. If there is no laser, it’s the problem of the laser power supply (optical coupled isolator) or laser tub...

This problem may cause from improper setting of the software. Please start up the laser software RDWorksV8. And then click “Config” – “system setting” on the menu bar. This dialog box appears. Make sure “Axis X mirror” is unticked, and “Axis Y Mirror” is must ticked. If your setting is different from this, this is the problem why your cutting/engraving reverse. Just reset the config as above.

If the file being imported is DXF format, the problem may be caused by improper software setting. For example, the unit of the original DXF file is “inch”, but in RDWorks, the DXF unit is set as “mm”. When you import the DXF graphic to RDWorks, the graphic will be read as “mm” unit. Therefore the size turn out in RDWorks is different from the original size. Please refer to below photo to set DXF unit in RDWorks : Please make sure DXF file unit from your drawing software is the same as RDWorks’ s DXF unit. Useful link: laser cutter reviews

If there are several USB interfaces with your PC, it's able for one PC ( laser software ) to connect with several machines. But pc will does only communicate with one machine and sending the file into the laser in the same time For USB connection as below 1. When connecting with the first machine, it's connected automatically as default. 2. When connecting with the second machine, please click the “Add” below, then click "USB" and choose COM3 (or other ports). 3. When connecting with more machines, it's the same as 2. (Just choose different COM ports) If you use Ethernet interfaces,please refer to the following video teaching you how to set network. And the way of adding more Ethernet port is the same as above.

1. Firstly run CorelDraw and set the parameter following below instructions: 2. After that, close CorelDraw. Double click to open RDWorks installation program. Choose the type of CorelDraw_Laser (be sure the RDWorks main program has been already installed), and then tick the item RDworks, as shown below: Click “install” and wait to compete the installation. 3. Again run CorelDraw. Choose and enter “Run Macro”(Tools > Marcos>Run Macro). Choose Marcos in: [Globalmacros (RDWorks15/16/17V8.gms)] > [RDWorksV8.UserInit]. Click run. 4. There will appear two extra buttons . Move them to anywhere you want them to be. After finish drawing the graphics, click “Laser running” to directly import the graphics into RDworks.

1. RDWorks cannot read PDF and open it directly. 2. Use CorelDraw to open/import PDF file. Then save the graphic as DXF file. Like below: 3. Then RDWorks can read the DXF file, Just import the DXF file into RDWorks directly. 4. The other way is open/import PDF file with CorelDraw，use the plugin button "Laser Running" to import the graphic into RDWorks. Useful Links: #laser cutter reviews     #laser machine

When I use laser cutter , I'd like to cut a Rectangle at 30x30mm, however, it become 30x60.2 in simulation and in laser, Please make sure "Enable rotate engrave" is not ticked. Useful link: Laser cutter reviews

If the software shows the below information: Please try the following solutions: A.Please check if the USB cable is loose or not. USB cable B.Please check if the USB is connected to the PC interface on the machine correctly C.Try connect to another USB interface on the computer D.Change another USB cable E.If you use a laptop computer, please cancel the energy saving mode. G.Reinstall the laser cutting machine software and drivers Useful link:  # Laser cutter reviews       # Laser cutter        # Laserengraverforum

If Laser cutter has a wrong cutting/engraving size, generally the pulse setting of the X/Y axis motors is wrong. Please follow the below steps to solve the problem Please draw a 100x100mm square using the cut mode and send to your laser cutter and cut the square. 100*100mm Let’s say the actual size of the square measured is 98x95mm 98*95mm How to fix this problem? Please follow the pictures below to find the “Vender settings “and then input the password. Click "Read" first.Now select the X/Y axis and revise the step length,input the numbers as the below, and the software will count the correct number automatically,then please click"Write"and then exit. After “Reset” on display and draw a new 100×100mm square, if the size is correct, the problem is fixed. If not, please repeat the step 1-3.

I believe that many friends who have laser cutting machines will encounter such problems. The quality of cutting products or engraving products made with laser cutter is very poor. Why is the quality of my laser cutting machine so bad? Is there a problem with the quality of my laser cutting machine? Sometimes this may be one of the factors. But today I will explain the reasons for this low quality. 1, the reason that affects the quality of cutting First, we need to know the measure of cutting quality. 1.Cutting surface roughness Rz Rz is one of the basic evaluation parameters for surface roughness that is widely used. Rz is more intuitive, but only reflects the peak-to-valley height of the surface profile being measured.Rz commonly used in the range of 0.1 ~ 25μm. Different roughness 2.Cutting slag size 3.Trimming verticality and slope u 4.Cutting edge rounded size r 5.Drag after the stripe n 6.Flatness F The related concepts above can be ch...
