Problem: System has no movement in any one axis.
Possible solutions:
1. Try to jog the problem axis using the X/Y/Z jog keys on the control unit. If OK, retry the job.
2. Check the table cable for a solid connection.
3. Call service technician for further instructions.
Problem: Unusually loud noises during the engraving process.
Possible solutions:
1. Isolate the cause of the unusual noise by:
a. Remove the cutter.
b. Turn the engraving motor to OFF.
c. Run the engraving job, or X/Y jog the system.
If the noise persists, it may be conned to the X, Y or Z-axis. Check for proper lubrication of
lead screws. Follow lubrication instructions in chapter 4.
If the noise goes away and to further isolate the cause, do the following:
a. Remove the motor belt.
b. Run the engraving motor without starting a job. Loose motor belts may cause some
noises, so removal will narrow down the problem. If the noise is present with the
spindle motor on, check the motor brushes.
If there is no unusual noise when running the spindle motor with no belt attached,
do the following:
a. Attach the motor belt.
b. Run the spindle motor and vary the RPM by changing the control unit potentiometer.
Noise levels may vary. If the noise persists, check the spindle for overheating. Excessive
overheating of the outside housing of the spindle is a sign of defective bearings. The noise may
be caused by the bearings.
Problem: Spindle is hot.
Possible solutions:
1. Ensure that the nose cone area is free of debris. Check the vacuum system (if used)
for clogging.
2. Inspect the spindle for other obstructions that may prevent proper rotation.
3. Bearings may need to be replaced.
Problem: Spindle motor will not come on.
Possible solutions:
1. Check the auto/on/off switch to ensure the proper operational mode.
2. Check motor brushes.
Problem: Motor belt will not stay on pulley.
Possible solutions:
1. Motor belt is probably worn and needs to be replaced.
