George,

I am very poor with words because my english is not very good.
Problem was that mirrors and head was not in line so it was impossible to get laser beam in center in all position.

I also made modification on second mirror so now I have more control on move it up/down and left/right

Mirror 2 and head was not in same level so it was impossible to get beam in center on both side.
Now I can move head up/down and left/right like on original.

Also I was unable to get straight beam with third mirror.
Now I can rotate all head and I have straight cut.

Now in all position I have laser beam in center of head.

Can someone tell me if it would be a better way to address this type of problem by remounting the tube to get it closer to the 90? thanks marty

[Zlatko Kursar]

Martin, I think that 90 between tube and first mirror is not critical because with this mirror you can direct beam in any direction. But first and second (and third) mirror must be in same level - horizontal and vertical.

[Alexa Ristow]

I have found that I could never get the beam 100% centered on the Head and stable across all 4 corners until I had the courage to start adjusting the tube mounts. If the beam is note centered on the first mirror, then it tends to drift left to right or up and down at the 4 corners. Whether or not the tube is 90 to the mirror is not as important as making sure the first mirror contact is dead center.

Regards,

Norman

Zlatko;
I am very interested in your red dot beam setup-any explanation and or drawings would be helpful. Thanks

After my wife burned red dot pointer because she had forgotten to bring this down, I made a new modification.
I insert the switch that shuts off power to the laser power unit if the pointer lifted.

Since I don't own the same brand of laser machine, is that drop down laser pointer OEM or something you designed? Either way I like it!

[Zlatko Kursar]

This is 3 USD for 5 pcs laser pointers

Got the Laser, just the mounting is what I have to do. My carriage is different but I have a small machine shop to make one to fit.

[Joseph Shawa]

Seems it would have been better to mount this on the second mirror so as to keep inertia lower on head.

[Kev Williams]

These things move so slow I doubt the extra weight would make much difference...

more than once I've taped small bottles of Testors paint to the top plate on the laser head of my LS900- makes a great paint mixer!
