Note: For several of these tips it is important to understand the difference between Vector files and Bitmap files. If there is a problem with the motor cable, it is best to replace all of them, not just one or two of them. Common Laser Engraving Problems and How to Troubleshoot. Concerning to engraving the bitmap graphics, we should debase the resolution ratio so as to increase the speed. Unlike the other options, it does not remove material from the metal surface. Low setting power for the laser tube. With the vector cut the laser just traces the lines of the cut. CO2 lasers are rarely a good choice because their wavelength is not absorbed well (they are good at marking organic materials such as plastics and wood, though). When cutting, the two ends sometimes cut into each other, sometimes separates. Proper considerations can save you a great deal of time and money.
If this affects production efficiency, set the "Number of repetitions" to a relatively large value in "Data Output" and set the corresponding dwell time in "Delay". Replace the fuse or reset the breaker if it's faulty. D: check whether the wiring related to the laser power supply is reliable, and check along the cable to see if there is anything abnormal. 2mm; d. Check the parallelism of the guide rails, straightness of the guide rail should be ≤0. If you're new to laser engraving, here are a few tips to help you get started. If so, please inspect the main contactor and control transformer. But if you want to give the edges of your engraving a little extra sharpness here's a good trick. Finally, once all the steps have been completed, replace any R103 and R28 that have not been adjusted. It may be because of the Z-axis feed motor problems, driver problems, bearings, foreign material jams, etc. The machine often shakes violently when it is moving. For a six-wire motor, the AC, A+, and A- are a set of coils, where AC and A+ are connected, and BC, B+, and B- are another set of coils, with the same continuity. Circulating cooling water quality is good, tap aluminum oxide is too serious, the use of regular cleaning of the pump and water pipes, water protection in the dirt, otherwise easily lead to laser tube burst or cold head off.
When processing the irregular materials, we should use the red laser positioning equipment to check whether the engraving position is correct at first, then to begin engraving. The second problem: Carving different depths or not deep. You can usually find replacement parts at your local hardware store or online store of your laser machines manufacturer.
Check in advance whether the machine has not been reset; please correct it if it has not been reset; 4. Whether the edited file is correct, re-edit if it is wrong); 2. The laser head pulley serious wear and tear, resulting in loose laser head, then replace the pulley. The smaller the depth of field, the smaller the focus size, which is beneficial to the cutting ability, but disadvantageous to the cutting depth. If you are having trouble getting a deep engraving, try adjusting the power or focus until you get the desired results. Carefully check and adjust the optical path of the lens to make the laser incident position at the four vertex corners fixed and reliable. Continuous emission, intermittent glow, unstable or uncontrolled current. This problem is caused by the non-parallelism of the feed active shaft and the trolley aluminum pass. Solution: The green data light will blink while a job is being sent from the computer; make sure the light has finished blinking before hitting "Go.
But the disadvantage of this trick is that the line is very thin. The surrounding yellow light is not strong when cutting, and the blowing is weak. This problem is generally caused by the servo limit line or the limiting displacement, which can be solved by changing the line or the limiting displacement. Computer operation is correct. To troubleshoot, here are some things you might need to do. Common Ruida Errors. The display panel does not light up. These are created by programs like Adobe Illustrator, Inkscape, AutoCAD and Corel. After the laser does the engraving it will come back and burn a thin line around the very edge. For some unfamiliar materials engraving, we should abide the KW high to low principle. Consider post-process treatments. Check to see if there are any errors in the original drawing, such as crossing, unclosed, missing strokes, etc., correct the errors in the drawing, and then output the test. The Fourth Problems: Reset is not normal. Step 3: Tip #3: Wood Grains and Engraving.
For example to cut through 1/8" plywood I would have the laser power at 100% and the speed at 20%, but to just score the wood I would set the power to 30% and the speed to 95%. Key points: water temperature, lens, laser tube position, laser path, laser tube). Tip: Leave a little space between the targets so you can set them down without bumping the ones around them. Check if the ground line wire off). If the trolley still fails to move, it is necessary to replace the 48V switching power supply. If there is no problem of the reflect mirror, zoom lens and laser ray, we should contact the maintenance man. If having a uniform look to the engraving is important to you, you'll probably get better results from a good plywood where the top layer is more uniform. E: replace the laser power supply or control board for testing. Only by reaching this standard can we ensure that the laser processing power density is stable in the whole working process. Improper light polarization. If the basic optical path, the optical path of the over-expanding mirror, and the dynamic focal length have been properly adjusted, but the light spot remains thick, it may be necessary to adjust the distance between the two lenses of the expander. When working, some places can be cut off and some places can not. One thing to be aware of is this works well with vector lines, where the laser/red dot traces the lines, but not so well with engravings where the laser pass back and for over the whole area of the engraving.
The selection of the lens is unreasonable, and the processing depth is not taken into account when adjusting the focal length, which leads to a poor focusing effect. Cause: While the laser cutter will never convert raster images into vector lines, it can convert vector lines into raster images if the vector lines are too thick. The laser tube may be aging and needs to be replaced.
