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木工雕刻機上由于一般步進電機和驅動器外殼未采用鋁、鈦、鎂合金外殼進行磁屏蔽，因此對高靈敏的接收機系統木工雕刻機造成干擾，使其無法工作，并且污染電源，造成控制系統的單片機和上位機無法進行通訊，嚴重者造成單片機死機，給正常使用造成了困難，因此干擾問題木工雕刻機必須加以解決。

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決：

The following measures can be taken:

A．加裝電源濾波器，木工雕刻機減少對交流電源的污染。

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

B．“一點接地”原則。將電源濾波器的地、驅動器PE（地）（驅動器與機箱底木工雕刻機板絕緣）、控制脈沖PULSE-和方向脈沖DIR-木工雕刻機短接后的引出線、電機接地線、驅動器與電機之間電纜防護套、驅動器屏蔽線均接到機箱壁上的接地柱上，并要求接觸良好。

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．盡量加大控制線與電源線（L、N）、電機驅動線（U、木工雕刻機V、W）之間的距離，避免交叉.比如我們在處理雙軸驅動系統中兩個處在同一機箱的驅木工雕刻機動器安裝位置時,一個驅動器銘牌朝前，另一個則朝后，并在結構布置上使這些引線盡量短。

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．使用屏蔽線減輕外界對自己的干擾，或自己（電源木工雕刻機線）對外界的干擾。

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

經過上述處理后，可以有效解決雕刻機干擾問題。

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