Problem description:

Waves appear when cutting straight line or circular.

Noted： Regularly check whether there is any dirt stuck between the belts and gears of the X-axis or Y-axis first, which may affect the trajectory of the belt. So we need to clean the side of the belt that contacts the gear. (To reduce belt wear.)

Reason:

1. The focus lens is loosen.

Solution:

Use the lens opener to lock the fixing ring.

2. The golden screw does not lock the laser focus tube tightly.

Solution:

Tighten it after adjusting the focus length.

3.The third mirror is not locked.

Solution:

Use the lens opener to lock the fixing ring.

4.The screws between the laser head and the shaft mode is not locked tightly, causing the laser cart to be shaken

Solution:

Use an Allen wrench to tighten the screws.

5. The coupling screws is loose.

Solution:

Use an Allen wrench to tighten the screws.

6. The belt is too loose or too tight.

Solution:

Use an Allen wrench to adjust the tightness of the belt.

7. The roller is too tight or too loose.

 Solution:

Adjust the tightness of the roller.

After you do that,If the problem still exists after checking the above,you can try the below method. 

​

Draw a X and Y straight line

Upload to the machine and start it（Only trace the line, not cut through）,check whether the X or Y tangent lines have ripples.

Note:The machines of Nova 51 and Nova 63 may have slight cutting waves, which is acceptable if it is within the error range (You can also send it to us for judgment and we will assist you).

Note: Recheck the X-Axis and Y-Axis,re-cut a straight line or use the following vector cut the file named ‘Vector cutting test.dxf' to check again.（You can also send the result to us for judgment and we will assist you）.

End.
