The machine suddenly can't work normally. The mechanical parts and electrical parts have been tested, but there is no reason to find out? Whether you encounter this problem. Fire speed electromechanical has summarized some experience, and I hope it can help you（ Huosu Electromechanical is committed to one-stop purchase of engraving machine and accessories)

1325木工雕刻机上由于一般步进电机和驱动器外壳未采用铝、钛、镁合金外壳进行磁屏蔽，因此对高灵敏的接收机系统木工雕刻机造成干扰，使其无法工作，并且污染电源，造成控制系统的单片机和上位机无法进行通讯，严重者造成单片机死机，给正常使用造成了困难，因此干扰问题木工雕刻机必须加以解决。

On 1325 woodworking engraving machine, because the general stepping motor and driver shell are not magnetically shielded by aluminum, titanium and magnesium alloy shell, it interferes with the woodworking engraving machine of the highly sensitive receiver system, makes it unable to work, pollutes the power supply, makes the single-chip computer of the control system unable to communicate with the upper computer, and in serious cases, causes the single-chip microcomputer to crash, It is difficult for normal use, so the interference problem of woodworking engraving machine must be solved.

可采取如下措施加以解决：

The following measures can be taken:

A．加装电源滤波器，木工雕刻机减少对交流电源的污染。

A. Add power filter to reduce the pollution of AC power supply.

B．“一点接地”原则。将电源滤波器的地、驱动器PE（地）（驱动器与机箱底木工雕刻机板绝缘）、控制脉冲PULSE-和方向脉冲DIR-木工雕刻机短接后的引出线、电机接地线、驱动器与电机之间电缆防护套、驱动器屏蔽线均接到机箱壁上的接地柱上，并要求接触良好。

B. "One point grounding" principle. Connect the ground of the power filter, the driver PE (ground) (the driver is insulated from the woodworking engraving machine board at the bottom of the chassis), the outgoing line after the short circuit of the control pulse pulse - and the directional pulse dir woodworking engraving machine, the motor grounding wire, the cable protective sleeve between the driver and the motor, and the driver shielding wire to the grounding column on the chassis wall, and the contact shall be good.

C．尽量加大控制线与电源线（L、N）、电机驱动线（U、木工雕刻机V、W）之间的距离，避免交叉.比如我们在处理双轴驱动系统中两个处在同一机箱的驱木工雕刻机动器安装位置时,一个驱动器铭牌朝前，另一个则朝后，并在结构布置上使这些引线尽量短。

C. Try to increase the distance between the control line and the power line (L, n) and the motor drive line (U, woodworking engraving machine V, w) to avoid crossing. For example, when we deal with the installation position of two woodworking engraving machines in the same chassis in the two axle drive system, one driver nameplate faces forward and the other faces backward, and make these leads as short as possible in the structural arrangement.

D．使用屏蔽线减轻外界对自己的干扰，或自己（电源木工雕刻机线）对外界的干扰。

D. Use shielded wire to reduce external interference to yourself, or self (power supply woodworking engraving machine wire) interference to the outside world.

经过上述处理后，可以有效解决雕刻机干扰问题。

After the above treatment, the interference problem of engraving machine can be effectively solved.
