CNC engraving machine appears some common problems how to do?

CNC engraving machine in the use of the process may encounter some common failures, in view of these common problems, you can take the following measures to solve:

First, the engraving machine single axis or multi-axis does not walk or walk is not normal

Check the control card: Confirm whether the control card is loose or faulty, and reinstall or replace the control card if necessary.

Check the driver: check whether the driver of the corresponding shaft is working properly. If there is a fault, it needs to be repaired or replaced in time.

Check the motor: the stepper motor or servo motor may be faulty, it is necessary to check whether the motor is running normally, if necessary, repair or replace.

Check the transmission parts: such as shaft coupling, screw, nut and other parts are loose or broken, if abnormal, need to tighten or replace.

Check the software Settings: confirm that the parameter Settings in the engraving machine software are correct, such as the driver fine score, current and other Settings are consistent with the software.

Second, there is dislocation or wrong size when carving

Check the software path: confirm that the path setting of the engraving software is correct and whether there is an offset.

Check the gap of the transmission parts: check the gap size of the lead rod and whether the fastening screw of the smooth rod is loose. If there is an anomaly, it needs to be adjusted.

Calibrate the machine: Calibrate the engraving machine regularly to ensure the straightness and perpendicularity of each axis.

Third, the spindle motor does not rotate or reverse

Check the frequency converter: confirm whether the parameters of the frequency converter are set correctly and whether the signal line is reversed.

Check the motor line: check whether the spindle motor line is in good contact, whether there is a break or short circuit phenomenon.

Check the controller card: Check whether the controller card is faulty and replace it if necessary.

Fourth, engraving machine engraved

Check the controller card: Check whether the controller card is faulty and replace it if necessary.

Check file path: Confirm whether the path of the engraving file is correct and whether the file is damaged.

Check software Settings: confirm that the Settings of the engraving software are correct, such as processing speed, curve acceleration and other parameters.

Fifth, the spindle motor suddenly stops or slows down during the working process of the engraving machine

Check the voltage: confirm whether the working voltage is stable, such as the voltage is unstable, you can install a regulator.

Check the line: check whether the motor line is connected and whether the wire end is derailing.

Check the limit switch: Confirm whether the limit switch is out of order, and replace it if necessary.

Sixth, the position of the engraving machine is uncertain when starting and resetting

Check the limit switch: Confirm that the limit switch is damaged or always closed, and replace it if necessary.

Check the driver cable: Check whether the driver cable is short-circuited or in poor contact. If the driver cable is abnormal, repair or replace it.

Seventh, other common problems

The engraving line is wide: adjust the focus of the focusing tube and adjust the current correctly.

After using the software for a period of time, the path cannot be generated: Check whether the USB dongle is normal, or reinstall the software.

Engraving machine noise: check whether the transmission parts lubrication is insufficient, add lubricating oil regularly.

preventive measure

Regular maintenance: regularly clean, lubricate and tighten the engraving machine to keep the equipment in good condition.

Standard operation: The operator must receive professional training and be familiar with the operation specifications and safety requirements of the device.

Choose high-quality accessories: When purchasing accessories, choose high-quality and reliable products to reduce the failure rate.

In summary, for the common problems of CNC engraving machine, it can be solved and prevented by checking the control card, driver, motor and other components, adjusting software Settings, regular maintenance and standardized operation.
