Why the engraving effect is not good?
Very few friends will encounter situations where the engraving effect is not good，why was that?
example one :
The original image:
The effect like :missing, skipping or dislocation.
The engraving effect is not good, there are several main reasons：
1-Machine assembly
Need to check the following parts：
1>Timing belt：The timing belt must be tightened and fixed
2>The screws of the synchronous wheel:Tighten the screws！
Three parts of the machine：
3>The screws of the coupling:Tighten the screws！
Check and adjust the above three points.
2-Focus of the laser was not very good
The focus is adjusted, the carved lines are very fine, otherwise the lines will be rough.
Adjusted the focus again please.Screw slowly
