Care & Maintenance
Whether you are a novice or a professional, you should do regular care and maintenance for 48"x96" CNC wood router kit and its accessories.
• The control cabinet should be placed in a well-ventilated place and cannot be placed in a high-temperature environment. Prevent the electrical components in the control box from malfunctioning due to high temperature.
• The machine should be placed in a dry and well-ventilated place (to prevent parts and accessories from malfunctioning due to exposure to the fuselage).
• The machine must be equipped with a reliable voltage stabilizer to ensure the safe grounding of the ground wire. At this point, the manufacturer has basically installed and debugged the customer in advance when configuring the control cabinet. It is best to consult before purchasing the machine.
• Try not to use the internet computer to transfer files to the machine. Computers connected to the network are likely to cause abnormalities in the machine through file transfer.
• The machine needs to be maintained every other month (add a proper amount of special lubricating oil to the screw rod and the guide rail rack). Now many manufacturers are equipped with manual or electric lubricators, which can realize faster feeding of the slider and the wire. The bar is filled with oil and does not need to be disassembled, making maintenance easier and faster.
• Maintain a good lubrication state, regularly check and clean the lead screw, add or replace lubricating grease and oil, so that the lead screw, nut and other moving parts always maintain a good lubrication condition to reduce the wear speed of mechanical parts.
• Do not allow the machine to work on the same part of the table for a long time (in case that the screw, guide rail and other transmission devices are not in contact with the beam for a long time and cannot be reasonably lubricated).
• Check whether the wiring and screws of the machine are loose within a certain period of time. It is best to tighten the screws regularly. This can also improve the accuracy of routing.
• Do not place debris (magnetic materials, corrosive items, overweight items, liquids) on the table or machine head.
Troubleshooting
The 4'x8' CNC wood router machine will inevitably have some problems during the day-to-day work. Some of the reasons are due to the configuration of the machine itself, and some of the reasons are caused by the misoperation of the user. Below we have listed some common problems and solutions for reference:
1. When setting the origin, the reason is sometimes shifted forward or shifted to the right and the shift distance is uncertain:
1.1. The limit switch is out of order. The limit switch has been closed and then bounced when the system returns to the system origin. Just change the limit switch.
1.2. The drive line is loose. Try to fix it tightly.
2. When the machine starts to reset, it makes an abnormal sound or always tops the limit switch:
2.1. The limit switch cannot be touched, just correct it.
2.2. The contact of the drive line is not good, just fix the drive line.
2.3. The limit switch wire is not connected properly, just connect the wire properly.
2.4. The limit switch is damaged, just replace it.
3. The reason why the machine cannot engrave at the origin:
3.1. Whether the layout size of the file matches the machine.
3.2. Check whether there is an offset (OFFSET) and whether the layout setting is correct.
4. The reason why the spindle motor suddenly stops or rotates slowly during the working process:
4.1. If the working voltage is unstable or overloaded, just add a voltage stabilizer.
4.2. Check whether the middle line is connected well and whether the end of the line is unsoldered.
