Key Switch

This light indicates if the key switch for the KLMC is cycled from ON to OFF. When the machine is

turned ON for use you must cycle the key switch to clear the red light. There is a five second delay

for the light to turn to green.

Laser Enable

This light will turn green once the cut or engrave file has started.

DSP Box

This box is an interface between the computer and the KLMC. The three indicator lights on this box

are POWER, USB/DATA and DSP ACTIVE.

The POWER light will turn green when the system is turned on. It will turn even brighter green

when you enter the Cut and Engrave menu or the Manual screen.

The USB/DATA light will blink green upon entering the KCAM Cut and Engrave menu or the

Manual/Test screen showing communications are taking place between the computer and DSP. It will

continue to blink green when the laser is running and will turn off once you have exited out of KCAM

or the laser system is turned off.

The DSP ACTIVE light will turn green when KCAM enables the DSP to operate.

Mechanical

Motion

The motion table has an X axis that travels left to right, and a Y axis that travels front to back. The

travel must be smooth and unrestricted in both the X and Y directions.

X Motion Test

Verify that your system is turned OFF, the shutter is closed, and then unplug the cable labeled X

Motor Power going into the servo amplifier at the front of your system. Manually push the laser

heads along the X axis. The laser heads should move smoothly, without any restriction. If there is

restriction, call the factory for further instructions. Plug back in the X Motor Power cable to the

servo amplifier.

Y Motion Test

Loosen, but do not remove the two bolts that hold the motor mount onto the bottom gantry. When

loosened, remove the belt. By hand, slowly move the gantry from the back to the front several times

to verify that there is no binding. If the lead screw is binding, call the factory for further instructions.

If motion is smooth, place the belt back around the two pulleys and tighten the two mounting bolts.

The pivot of the mounting bracket will self-tighten the belt to the proper tension.

Lead Screw

To test the Y axis lead screw, check that the lead screw holding brackets are tight and that the lead

screw DOES NOT TURN. The lead screw should be locked tight and the nut turns on the lead screw.

The gantry should be very hard to move the Y axis with the belt on. If the gantry moves freely the

nut may be loose. Please refer to the Maintenance chapter of this manual for Lead Screw Nut

Adjustment.
