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:

部分保丽龙雕刻机上的步进电机和步进电机驱动器外壳没有采用铝、钛、镁合金外壳进行磁屏 蔽，对高灵敏的接 收机系统就造成一些干扰，使其无法 正常工作，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，严重的可造成单片机死机，给模具雕刻机的正常使用造成了不必要的麻烦，因此模具雕刻机的干扰问题一定加以解决。

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.

对于保丽龙雕刻机出现的一些干扰问题可采取如下措施加以解决：

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

1.可加装电源滤波器，减少对交流电源的污染。

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

2.“一点接地”原则。将电源滤波器的地、驱动器PE（地）（驱动器与机箱底板绝缘）、控制脉冲PULSE-和方向脉冲DIR-短接后的引出线、电机接地线、步进电机驱动器与步进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。

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.尽量加大控制线与电源线（L、N）、电机驱动线（U、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。

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 蔽线减轻外界对自己的干扰，或自己（电源线）对外界的干扰。

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

经过上述处理后，系统工作可靠。

After the above treatment, the system works reliably.

一般按照上面的内容进行处理就不用担心保丽龙雕刻机在使用的过程中会受到干扰问题的严重影响了，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.
