What are the common faults of CNC engraving machine

CNC engraving opportunities to the following common failures
1. When the button moves, the axis moves in my direction.
Solution:
1. Check whether the optical lotus root line is working normally and whether the line is in good contact;
2. Check the motor circuit for welding faults.
 
2. The sending software cannot be opened normally, and the sculpture is deformed.
Solutions:
1. Reinstall the new system and software;
2. Check whether the screw and screw on the X-axis and Y-axis are loose;
3. Engraving tools have problems.
 
3. Signal cannot be transmitted:
Solutions:
1. CNC engraving machine parameters and computer Settings are correct.
2. Whether the signal wires are connected correctly.
 
4. The carving material is unclean.
Solutions:
1. Tools are blunt and must be worn, so they need to be ground.
2. Whether the tool Settings in the software are consistent with the actual tools used.
3. Whether to add lubricant when carving hard materials (such as metal, jade, glass, etc.).
4. Whether the knives are concentric.
 
5. The head cannot be reset to zero, and the size of the CNC engraving machine is reduced or beyond the boundary.
Solutions:
1. The nose cannot be reset to zero or the lead screw is put in the wrong position.It is necessary to adjust the lead screw.
2. Travel switch is damaged.
3. The head cannot be reset to zero, and the size of the CNC engraving machine is reduced or exceeds the boundary.Maybe the "model" in the machine setup doesn't match the actual model.
 
6. Operation error of knife.
Solutions:
1. No ground wire is installed, showing static electricity, causing the operation and dislocation of the knife.
2. The printer parameters in the software are inconsistent with those of CNC engraving machine.
 
7. Knives are often broken when carving hard material.
Solutions:
1. When carving hard materials, different engraving parameters and tools should be set according to different data.
2. Choose the right lubricant.
 
8. When the CNC engraving machine starts to reset, it beeps, or the limit switch is always good or bad.
Solutions:
1. If the ejector bar does not reach the limit switch, just align it.
2. Poor transmission line contact.Try to secure the drive wire firmly.
3. The limit switch wire is not connected properly, only need to be connected correctly.
The limit switch is broken, just change it.

9, CNC engraving machine can not be engraved in the origin.
Solutions:
1. Whether the layout size of the file matches the machine.
2. Check whether offsets are set and the layout is set correctly.
 
10, CNC engraving machine spindle motor suddenly stopped or slowed down.
Solutions:
1. If the working voltage is unstable or overloaded, increase the voltage regulator.
2. Check whether the intermediate line is well connected and whether the thread ends are unglued.
 
11. When the CNC router sets the origin, sometimes the offset interval between the forward and right is not fixed?
Solutions:
1. When the limit switch fails, the limit switch will first close and then pop open when the system returns to the origin.Just change the limit switch.
2. Loose transmission.Try to fix it.
 
12. When the CNC engraving machine starts to reset, the positions of X-axis, Y-axis and Z-axis are not fixed.
Solutions:
1. Limit switch is broken (limit switch is always off), just replace it.
2. Transmission line fracture (short circuit of X 14 pin and 15 pin, Y 13 pin and 15 pin, z 31 pin and 15 pin).Replace drive line or separate short circuit.
3. The drive board is broken.Replace the drive plate.
 
13.CNC engraving machine cannot be engraved in its place.
Solutions:
1. Whether the layout size of the file matches the machine.
2. Check whether offsets are set and the layout is set correctly.
 
14, CNC engraving machine spindle motor suddenly stopped or slowed down.
Solutions:
1. If the working voltage is unstable or overloaded, increase the voltage regulator.
2. Check whether the intermediate line is well connected and whether the thread ends are unglued.
 
15. When the CNC router sets the origin, sometimes the offset interval between the forward and right is not fixed?
1. Limit switch fails. When the system returns to the origin, the limit switch is closed and flipped back on.Just change the limit switch.
2. Loosen the transmission line.Try to fix it.
When the CNC engraving machine is started and reset, the positions of x, Y and Z axes are uncertain.
Solutions:
1. Limit switch is broken (limit switch is always off), just replace it.
2. Transmission line fracture (short circuit of X 14 pin and 15 pin, Y 13 pin and 15 pin, z 31 pin and 15 pin).Replace drive line or separate short circuit.
3. The drive board is broken.Replace the drive plate.
 
16. When the CNC engraving machine starts to reset, it buzzes, or the limit switch is always good or bad.
Solutions:
1. If the ejector bar does not reach the limit switch, just align it.
2. Poor transmission line contact.Try to secure the drive wire firmly.
3. The limit switch wire is not connected properly, only need to be connected correctly.
The limit switch is broken, just change it.
