58 VE810 Engraver Manual
Mechanical Problems
Problem: No X, Y or Z-Axis movement.
Possible solutions:
1. Check that the controller power is on.
2. Check the power cable to make sure it is plugged in properly to the VE-810.
3. If the power cord is plugged in to a power strip, make sure that the power strip is
working properly and turned on.
4. Check to make sure that the X-Y Speed knob on the front panel is turned all the way
clockwise.
5. Ensure that the job has been transferred to the controller (Green start light is flashing).
6. There is a blown external fuse. Change the external fuses. See Chapter 5.
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 front panel. If OK, retry the
job.
2. There is possibly a bad microstepper board in the machine. Contact your distributor or
Vision.
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 confined to the X, Y or Z-axis. Check for proper lubrication
of lead screws. Follow lubrication instructions in chapter 5 - Lubrication. 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.
