Z Position

State – Numerical Value (0.000)

The Z position sensor monitors the relative position of the up-and-down

motion of the cutting truck. To check this sensor move the cutting truck all

the way to the top of its vertical travel and record the displayed numerical

value. Now move the truck all the way to the bottom of its vertical travel

and then back to the top. If the sensor is operating correctly the displayed

value will match the one previously recorded.

X Position

State – Numerical Value (0.000)

The X position sensor monitors the relative movement of the sandpaper

belt drives. This is more difficult to check but can be done by pushing the

front belt towards the back of the machine by hand. The displayed

numerical value will change as the belt turns.

Brd Tracking

State – Numerical Value (0.000)

The Board Tracking sensor tracks the position of the workpiece as it

travels in and out of the machine. A small brass wheel rides along the

bottom side of the material and provides position information to the control

system. It is extremely important that the workpiece have a very flat and

defect free surface 3/8” in from the edge on the bottom side of the

workpiece in order to operate correctly. To check the operation of this

sensor first make sure that the brass wheel on the board tracking sensor

has the black rubber o-ring in place and is spinning freely. Spin the wheel

and verify that the value displayed on the LCD is changing.

Probe State

State – Open/Closed

With no probe installed, the Probe State will be displayed as Open. The

operation of the probe can be checked while installed in the quick changer

and plugged into the connector. Once installed the LCD will read Closed.

To check the operation of the probe simply reach in and deflect the probe

tip to the side. If the probe is operating correctly the displayed state will

change from Closed to Open.

Cut Sensor

State – Numerical Value (0)

This sensor monitors the RPM of the cutting motor and feeds that

information back into the control logic. As a quick check, spin the spindle

by hand and check to see that the displayed numerical value changes. It

reads one count for every revolution. At low speeds it will only change

from 0 to 1 or 2.
