COMMON X, Y and Z-axis issues on ULS LASER ENGRAVERS
COMMON X-axis issues
X Axis issues are the most common mechanical issue within all ULS systems. Because the main source of movement within these machines is back and forth, it is nearly a guarantee some of these parts will need to be replaced with relative use.
If you are noticed a loss of quality within your ULS machine overtime such as smudgy etches within the left-right plane, horizontal ribbing your material, double imaging, or jagged edges left to right, there is a likelihood parts within your X axis arm are due for a replacement.
The first and easiest test for X axis issue is to manually move the carriage. With your Universal Laser turned off, move the carriage back and forth to either end of the X axis. If you notice anything usual, such as the carriage feeling bumpy or rigid, or more resistance in some places than others, this is your first indication of an X Axis related issue.
Next, inspect the carriage of the machine. You will notice three- or 4-wheel bearings on your machine that hold the carriage in place to the X rail. Do these wheels have any noticeable scuffing or shedding on them?
Now, let’s look at the X rail itself. This is where those wheel bearings ride on. Your axis arm should be made of anodized aluminum plated black. However, this rail line can become scuffed and discolored overtime, indicative of not a smooth rail. If you notice this on your X rail, that could be the cause of your X axis failure.
Finally, take a look at the belt of the X axis connected to the carriage. This connects to the X motor which controls movement. Is the belt noticing any signs of wear, and it the belt not taught with the carriage system? If so, that could be the source of your X axis failure.
In conclusion, X Axis issues are a common problem in ULS systems and can cause loss of quality in your machine. By performing a manual check of the carriage, inspecting the wheel bearings and the X rail, and checking the belt connecting to the X motor, you can identify potential X Axis related problems. Regular maintenance and prompt replacement of worn-out parts can help ensure that your ULS machine operates smoothly and delivers optimal results.
COMMON Y-axis issues
On Universal Laser Machines, the Y axis, up and down movement, moves significantly less than that of the X axis. Consequently, it is far less often that you need to change parts related to it. In fact, depending on your usage, you may never need a repair. However, poor cleaning and heavy use will eventually wear down these parts as well. If you are noticing a loss of quality within your ULS machine overtime such as smudgy etches within the up-down plane, vertical ribbing your material, or jagged edges top to bottom, there is a likelihood parts within your Y axis are due for a repair. Here are a few notable symptoms of a Y axis issue.
The Y Axis when correctly aligned should be square with the bed of the machine. With a ruler or tape measure, move the X axis arm to the top of the machine, and measure the distance from either end to the front side of the machine. Complete this on both sides of the arm. If everything is aligned correctly, both sides should be of equal distance to the front side of the machine bed.
Our next step is a manual check the movement of the Y system. With the machine off, move the X arm up and down on the bed. This movement should feel smooth with a consistent amount of resistance. However, if you notice when performing that the movement feels bumping or jagged, this could be an indication of a Y related issue. While you are doing this, be sure to visually inspect the Y wheel bearings located on either side of the X arm. If any of these wheels are not spinning, this could be indicative of an Y issue as well.
Finally, visually check for wear on the belts and the Y motor located in the front on the machine under the top door covering. Your Y motor system should be clean and belts should be taught. However, if you notice a heavy amount of grime and shedding in the belt system, this could be indicative of a Y related issue.
In conclusion, although Y Axis issues are less common in Universal Laser Machines, regular maintenance and inspection can prevent any potential problems. By checking the alignment of the Y Axis, performing a manual movement test, and inspecting the wheel bearings, belts, and Y motor, you can quickly identify any issues related to the Y plane. In case of any persistent problems, it is recommended to seek professional help to ensure that your ULS machine is functioning optimally.
COMMON Z-axis issues
Z axis problems, or problems with the up and down movement, are among the more common issues you may encounter with your laser cutting machine.
The Z system operates with a set of screws connected by pulleys driven by the Z motor. If there’s a problem with any of these components, the Z motor won’t function correctly. Other issues, such as with the CPU or power system, can also impact the Z system.
If your Z axis isn’t moving, it’s a clear sign of a Z axis issue. But, if you also hear loud noises when moving the Z bed or if the top of the bed is uneven with the carriage, these are also signs of a Z axis failure. Uneven tables can cause imperfections in laser cutting as the lens won’t be properly focused on all corners of the machine.
In conclusion, Z axis problems are a common issue in laser cutting machines. These problems can be caused by various factors, including issues with the Z system components, the CPU, or the power system. If you suspect a Z axis issue, it is important to identify the problem as soon as possible to avoid any negative impact on your laser cutting process. By listening for loud noises, checking for an uneven bed, and confirming if the Z axis is moving, you can quickly identify the issue. If you are unsure of the problem, it is best to seek professional help to ensure your laser cutting machine is functioning optimally.
