Step 6: Set Up the Electronics
The electronics cabinet contains the Warthog controller, power supply, and variable-frequency drive (VFD),
which controls the water-cooled spindle. The Warthog controller uses the 36-volt power supply to power the
motors and gantry. Warthog uses a combination of optical isolation and an RS-422 serial connection to the
computer for increased immunity from electrical noise and static discharge.
Included with the electronics cabinet is a separate Warthog Computer Adapter that will be the connection point
between the electronics cabinet and your machine-control computer. An RS-422 Ethernet cable is used to
connect the electronics cabinet to the Warthog Computer Adapter; however, the machine and its components
are not Ethernet devices.
WARNINGS:
•
Always turn off the power switch on the electronics cabinet after using the machine.
•
Before opening the electronics cabinet, always turn off the power switch AND unplug the power
cable from the outlet.
•
Do not use the RS-422 Ethernet cable to connect the electronics cabinet or computer adapter to any
Ethernet-enabled device, such as a modem or internet router.
•
Always ensure the two fans on the side of the electronics cabinet are completely clear to ensure they
receive plenty of airflow.
Connecting the Electronics Cabinet
1.
Place the electronics cabinet on the base of the workbench or on the floor beneath it.
2.
Locate the RS-422 Ethernet cable exiting the rear cable channel of the electronics cabinet.
3.
Plug the RS-422 cable into the Ethernet port on the Warthog Computer Adapter.
4.
Plug the USB C-to-A cable into the USB-C port on the computer adapter.
5.
Place the computer adapter on top of the electronics cabinet lid or affix it to the side of the workbench.
6.
Insert the power cable into the jack on the side of the electronics cabinet.
7.
Plug the power cable into an outlet.
