1. Check whether the path of carving software is correct or not
2. Check the clearance size of the screw rod and whether the fastening screw of the smooth rod is loose
3. Check that the software parameters are set correctly.
8) when the X-axis of the engraving machine walks a certain section, the z-axis does not lift the knife, but press up to go down
1. Check whether the z-axis stepper motor is in normal operation, the power and the driver current or its own fault
2. Check whether the line of the z-axis stepper motor has bad contact or is in the middle of disconnection
3. Control card failure.
9) the spindle motor of the engraving machine does not turn or reverse
1. Check the parameter setting of the frequency converter
2. Whether the signal line of the inverter is connected backwards.
10) when the engraving machine opens the software and starts up, the shaft appears to close
1. Drive problem or bad contact of computer output signal line
2. Motor wire contact is poor.
11) the limit phenomenon appears in the engraving process of the engraving machine
1. Check whether the carving path exceeds the carving range
2. Soft limit set by parameters in the software.
12) the engraving machine sending software can not be opened normally, the thing carved is deformed.
1. Re-install the new system and software
2. Check whether the screw of X and Y axis is loose;The carving knife has problems.
13) the spindle motor stops or slows down suddenly in the working process of the engraving machine
1. If the working voltage is unstable or overloaded, add a voltage stabilizer
2. Check whether the middle line is well connected and whether the thread head is out of welding.
14) when the engraving machine sets the origin, sometimes the offset distance to the right is uncertain
1. The limit switch fails. In the process of the system returning to the system origin, the limit switch has closed and bounced off
2. The drive line is loose, try to fix it tightly.
15) the position of X axis, Y axis and Z axis is variable when the engraving machine is started and reset
1. The limit switch is broken (the limit switch is always closed), it can be replaced
2. The drive wire is broken (short-circuit between 14 and 15 pins in X axis, 13 and 15 pins in Y axis, 31 and 15 pins in Z axis). Change the drive wire or open the short circuit
3. If the drive board is broken, replace it.
16) the spindle of the engraving machine stopped
1. Short circuit inside the spindle
2. Current shielding
3. Inverter parameter setting is wrong or its own fault
4. Control card failure
5. Short circuit of spindle or data line.
17) the rotation sound of the main shaft of the engraving machine is abnormal
1. Frequency converter setting is wrong
2. Spindle does not turn
3. There is something wrong with the spindle itself (bearing damage).
18) the direction of the engraving machine is opposite when walking or returning to the mechanical origin
