How to solve some interference in the working process of engraving machine?

When we use the engraving machine, we must ensure that it works smoothly without any interference, so as not to affect the efficiency of the engraving machine and to get better working results. However, if there is some interference when the engraving machine is running, we can only solve it quickly. The following is the response to some interference: the stepping motor and driver shells of general engraving machines do not use aluminum, titanium and magnesium alloy shells for magnetic shielding, thus causing interference to highly sensitive receiver systems, it makes it unable to work and pollutes the power supply, causing the MCU of the control system and the upper computer to be unable to communicate. In serious cases, the MCU crashes and causes difficulties for normal use. Therefore, the interference problem must be solved. First, try to increase the control line and power line (L, N), Motor drive line (U, V, W)The distance between them, avoid crossing. For example, when we deal with the installation position of two drives in the same chassis in the dual-axis drive system, one drive nameplate faces forward and the other faces backward, and make these leads as short as possible in the structural arrangement. Second, the principle of 'One point grounding. The ground of the power filter, the driver PE (Land)(Drive insulated from chassis backplane), Control PULSE-And direction pulse DIR- The lead-out line after short circuit, the motor ground wire, the cable protective sleeve between the driver and the motor, and the driver Shielding Wire are all connected to the grounding column on the chassis wall and require good contact. Third, use shielded wire to reduce the interference of the outside world to oneself, or oneself (Power cord)Interference with the outside world. Four, install power filter, reduce the pollution of AC power supply. In short, the engraving machine needs everyone's attention at all times in use, so as to avoid problems that we did not find in time to cause some major accidents.
