If you encounter interference in the process of using styrofoam engraving machine, you must take measures to solve it in time, so as to avoid affecting the follow-up work and causing serious losses. So when the styrofoam engraving machine in the process of running interference phenomenon should be how to deal with it? The following article introduces the specific methods:

部分保麗龍雕刻機上的步進電機和步進電機驅動器外殼沒有采用鋁、鈦、鎂合金外殼進行磁屏 蔽，對高靈敏的接 收機系統就造成一些干擾，使其無法 正常工作，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，嚴重的可造成單片機死機，給模具雕刻機的正常使用造成了不必要的麻煩，因此模具雕刻機的干擾問題一定加以解決。

The shell of stepper motor and stepper motor driver on some styrofoam engraving machines do not use aluminum, titanium, magnesium alloy shell for magnetic shielding, which will cause some interference to the highly sensitive receiver system and make it impossible Normal work, and pollution of power supply, resulting in the control system of single-chip microcomputer and upper computer can not communicate, serious can cause single-chip computer crash, to the normal use of mold engraving machine caused unnecessary trouble, so the interference problem of mold engraving machine must be solved.

對于保麗龍雕刻機出現的一些干擾問題可采取如下措施加以解決：

The following measures can be taken to solve some interference problems of styrofoam engraving machine

1.可加裝電源濾波器，減少對交流電源的污染。

1. Power filter can be installed to reduce the pollution of AC power supply.

2.“一點接地”原則。將電源濾波器的地、驅動器PE（地）（驅動器與機箱底板絕緣）、控制脈沖PULSE-和方向脈沖DIR-短接后的引出線、電機接地線、步進電機驅動器與步進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。

2. "One point grounding" principle. Connect the ground of power filter, driver PE (ground) (insulated between driver and chassis bottom plate), outgoing line after short circuit of control pulse - and direction pulse dir -, motor ground wire, cable protective sleeve between stepper motor driver and stepping motor, driver shield wire, and good contact is required.

3.盡量加大控制線與電源線（L、N）、電機驅動線（U、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。

3. Try to increase the distance between control line and power line (L, n) and motor drive line (U, V, w) to avoid crossing. For example, when we deal with the installation position of two drivers in the same chassis in a two axis drive system, one driver's name plate should face forward, the other should face backward, and the structural arrangement should make these leads as short as possible.

4.使用屏 蔽線減輕外界對自己的干擾，或自己（電源線）對外界的干擾。

4. Use shielded wire to reduce the interference from the outside or the interference from the power line.

經過上述處理后，系統工作可靠。

After the above treatment, the system works reliably.

一般按照上面的內容進行處理就不用擔心保麗龍雕刻機在使用的過程中會受到干擾問題的嚴重影響了，可以放心使用。

Generally according to the above content to deal with, do not worry about the mold engraving machine in the use of the process will be seriously affected by interference, you can rest assured that use.
