Workaround wood engraving machine stepper motor driver interference
Workaround wood engraving machine stepper motor driver interference
As the general woodworking engraving machine 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 the power of pollution, resulting in single-chip control systems and PC can not communicate, causing serious microcontroller crash, caused difficulties for normal use, so interference problems must be addressed. 
May take the following measures to solve them: 
A. Install a power filter, reducing contamination of the AC power. 
B. "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. C. 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, a drive plate forward and the other backward, and so on the structural arrangement of these leads as short as possible. 
D. Use shielded cables to reduce outside interference on their own, or their own (power line) interference with the outside world. 
After the above processing, the system is reliable.
