How to deal with a motor not working:
- Ensure that the machine has successfully connected to the computer's laserGRBL software. The motor cannot be controlled if the connection is unsuccessful.
- Check if the motor cables are properly installed. (You can try reinstalling them)
- If there are other motors that work properly, open the control box to locate the main control board and interchange the motor cables inside the control box. If after the interchange, the motor still doesn't work properly, it indicates a problem with the cables. Please inform us, and we will send replacements.
- If the motor vibrates but does not move, there may be an issue with the wiring sequence. Use a tool with pointed ends to interchange the sequence of the middle two wires.
- After interchanging the sequence of the wires, if the direction is incorrect, interchange the sequence of the two wires on the left side.
occurrences of missed steps or offsets during engraving:
- It could be due to the synchronous belt being too tight; loosening it slightly may help.
- It could be because the engraved object is too light, causing it to slip during rotation and resulting in missed steps or offsets.
- It could be because the distance between the two rotating rods is too close, causing the engraved object to slip during rotation and leading to missed steps or offsets.
- Engraving settings set too fast can also lead to missed steps or offsets.
