OPERATOR’S MANUAL FOR LS SERIES

Mirror #2:

This mirror is located directly at the end of the gantry rail. This mirror should be

cleaned at least every two months. Use the same directions as found for mirror#3

Mirror #1:

This mirror is located directly in front of the laser tube. This mirror should be cleaned at

least every three months. Use the same directions as found for mirror#3 Laser tube

output coupler lens: This lens is located inside the output end of the laser tube. This

lens should be cleaned at least every three months. You must be very careful when

cleaning this lens. This lens cannot be removed from the laser tube. You can use a Q-tip

for applying the acetone. Be gentle. The ideal situation is that you are only removing

dust, film contaminate from humidity, or smoke fumes. Do not scratch this lens. It is

not replaceable. Linear rails: The linear rails are the guiding rails along the left and right

sides, and across the gantry. These rails should be clean, without rust, and have a slight

glaze coating of some oil. The linear rails should be given some attention about every

month. The surfaces of the metal should always have oil on it such that it is wet to the

touch.

The best way to see that you need to do some cleaning is to check the end of the rail

near where the home switch is located. If you see a dirt line, then clean the rails off and

apply fresh oil.

Linear bearings:

The linear bearings are found under the gantry (to mount the gantry to the side rails)

and under the focal head (to mount the focal head to the gantry). These bearings have

grease fittings for pushing lubricant into the ball bearing areas. You might not have a

special grease pump to lubricate the bearings. Try the cheap and easy approach. 1)

Remove the grease fitting, 2) Apply the grease to your finger, 3) Push the grease into

the little hole, 4) push more grease into the little hole, 5) go to step #2 ..... 6) Put the

grease fitting back on.

Rubber belts:

The rubber belts should be checked for appropriate tension at least every six months.

You should expect the two side belts to be the same tension and should be tensioned

at the same maintenance schedule. These side belts work together to move the gantry

from front to rear. If one belt is tensioned more often than another, then that belt

could become stretched more than the other. It is difficult to describe how tight the

belts should be, but there should not be a slack, sagging, or flapping. If the belt appears

to be worn on one side, check the bearing alignment or damage to the matching

bearings. There are many laser machine designs, but the method of changing the belt

tension should not be too complex. It is normally a method of tightening a screw and

then applying a lock nut to keep the screw in place.
