Four types of unusual problems

1: playing a BIF, a large table appeared at the edge of the square of the initial amplitude of low frequency oscillation.

why: when playing a BIF, from a square to a square, this process is a quick jump process, if the lens loose paste, can make the lens in the high jump greatly swing, so that the linear range of typing a lot of volatility.

processing methods: stick the lens firmly.

2: always play in the process of marking 45-degree diagonal lines.

reasons: on the driver board has a choice of X axis and Y axis pin, when two shaft driven plate bolt are choosing the same axis, two axis speed of movement of the same, according to the principle of the synthesis of speed, when the X axis and Y axis with the same speed, their synthetic velocity direction of 45 degrees, so the marking is always playing 45-degree diagonal lines.

3: start the galvanometer, the vibrating mirror driven plate on the green light is not bright.

the reason: the galvanometer driver board without electricity or driver board damaged.

processing method: put the bolt is in the right place.

4: in the process of marking, the galvanometer, yellow designator light not bright.

: the driver board did not receive the location of the control card data.

processing method: check the control card and signal lines are correct.
