1: When BIF is played, the oscillation with large amplitude and low frequency appears at the beginning of the square.

Cause: When playing BIF, jump from one square to another. This process is a fast empty jump process. If the lens is loose, it will cause the lens to swing greatly in the high-speed jump, so that the straight range of the play has a great fluctuation.

Treatment: stick the lens firmly.

2: The marking process is always marked with a 45 degree diagonal.

Cause: There is a selection pin for X axis and Y axis on the drive board. When the pins on the drive board of both axes select the same axis, the movement speed of the two axes is the same. According to the speed synthesis principle, when the X axis and Y axis have the same speed, their combined speed direction is 45 degrees, so the marking is always marked with a 45 degree diagonal.

3: When the galvanometer is started, the green indicator on the galvanometer drive plate does not light up.

Cause: The galvanometer drive plate is not powered on or damaged.

Processing method: insert the pin into the correct bit value.

4: During the marking process, the galvanometer does not move and the yellow warning light does not light up.

Cause: The drive board did not receive the position data of the control card.

Processing method: check whether the control card and signal line are correct.
