Woodworking engraving machine distribution box with electromagnetic interference
Recently often hear some former clients consult us before buying the other manufacturers of woodworking engraving machine electromagnetic signal interference occurs how to solve the problem through our engineers to analyze, the study found was due to the general stepper motor and drive housing is not aluminum, titanium, magnesium alloy casing magnetically shielded, so the sensitivity of the receiver system cause interference, it can not work, and pollution power, causing the microcontroller and PC Jinan engraving machine control system can not communicate, resulting in serious crashes microcontroller, caused difficulties for normal use, so interference problems must be addressed. 
Woodworking engraving machine can take the following measures to solve them: 
Install a power filter, reducing contamination of the AC power. 
"A little ground" principle. The power supply filter, the drive PE (ground) (driver and chassis floor insulation), the control pulse PULSE-and direction pulse lead DIR-shorting after the motor ground wire cable between the drive and the motor protective cover, drive shielded wire are connected to the chassis grounding screw on the wall and asked good contact. 
Try to increase the control cable and power cable (L, N), from the motor drive cable (U, V, W) between avoid cross, such as we are dealing with two dual-axis drive system drives in the same enclosure installation position, woodworking engraving machine forward a drive plate, the other toward the rear, and on the structural arrangement of these leads as short as possible. 
Use shielded cables to reduce outside interference on their own, or their own (power line) interference with the outside world.
