Engraving machine interference, want to sweep signal interference, can try:

First: we can after the installation of power supply filter to reduce the AC power pollution.

Secondly: the "ground", the power supply filter, carve machine drive (drive insulation and chassis backplane), between the motor ground, drive and motor cable protective sleeve are connected to the chassis, drive shield wall of the grounding pole, and requests a good contact.

Again: as far as possible to increase the control line and the power line, motor drive line between the interval, prevent alternate. Finally: the use of shielding line specific reduce the outside interference.

Shanghai engraving machine, all the normal operation of the machine!
