Functions Using the Switch Panel on the EGX-20
In addition to the usual operations using the switch panel, you can also use the switch panel to carry out operations like the
ones described below.
Carry out the following operations with the power to the EGX-20 switched off and the EGX-20 disconnected from the AC
adapter.
Displaying the Working Time of the Spindle Motor
During normal operation, if the Z-axis light flashes slowly for ten seconds (four or five flashes) when you turn on the power,
it means the spindle motor has been powered up for over 1,000 hours.
The spindle motor is a consumable part. As a general guide, we recommend replacing it after every 1,000 hours.
You can also use the following procedure to check the number of hours that the spindle motor has been powered.
1. While holding down the View button on the switch panel, insert the AC adapter into the EGX-20.
The illumination and flashing of the Z-axis light, Power light, View light, and Origin Set light show how many hours the unit
has been powered up.
2. After you have verified the time, press the View button. This switched off the power.
