Part 4 - Getting Started
Basic Machine Tests Now that you have your CNC machine all assembled and wired, it is time to make sure that it operates correctly.
This is the recommended start up order for the system.
1. Make sure that the USB cable from the CNC machine is plugged into your computer, then start the computer.
2. Start the Candle program and verify in the status window that no errors are showing. Normally, it will show “Idle” if it has connected
to the Controller Board properly. If an “Alarm” error is showing, with your mouse, click the Candle “Reset” then “Unlock” buttons in
that order to get to the “Idle” condition.
3. Make sure that the 24-volt power supply is connected to the Controller Board and then to the power mains. - Turn on the Controller
Board by pressing the white “On/Off” button.
4. Next, click on the “Spindle “button to turn on the spindle motor. Move the slider left and right to verify that the motor speed changes.
5. Set the “Feed:” to a value in the 200 to 500 range. With the mouse, click on the left set of direction buttons to verify that the X and Y
axes are moving. In a like manner, click on the rightmost up and down buttons to verify that the Z axis is moving. If all of these tests
complete without any issues, you can be assured that your CNC machine is working correctly. Shutting the machine down uses the
reverse of the startup process.
6. Turn off the Controller Board.
7. Unplug the 24-volt DC supply from the mains.
8. Shut down the Candle program. - Turn off the computer. Remember, if you run the CNC machine from the Offline Controller, the
USB cable must be disconnected from the Controller Board.
