RF is probably bad. If not then you have a modulation signal issue

It will be hard to find a decent made machine for $15K that will have a decent amount of power for deep engraving. You would need a small field or a lot of power.

I have LeeLaser875MQ...

We are looking for sales leads to move some of our remaining inventory on used machines that we have here in the shop.

We offer C02 and YAG machines all that can be seen here .......

Just thought I would shoot a quick video of how it is done in house.

YouTube - Brick Laser Engaving

We charge $.50 a brick to have this done with a $50 minimum for anyone interested.

What else are you going to be doing with the machine?

We are not able to help you with a machine because of the price point but if it was me I would build a 20W fiber on an xy motion table. Cost...

Just how we quickly set up the job. It is a proof of concept video for a prospective customer. They required a working video.

None taken just didn't understand. But I would take them on anyway. Do I win a 40w engraver?? :)

Not quite sure what this means, please elaborate.

Depending on the quantity we can do this. Are you looking to engrave photos? The Kern system would not be large enough for you and would take forever because it is a flying optic system, plus...

I dont believe that would be apples to apples, they use Chinese tubes.
Our machines are built mainly for industrial use. I believe they are more of a hobbyist system. We build machines that can...

We purchase used laser equipment.

Based on popular demand here is a quick video of the system in motion.

Here is a closeup of the engraving. Note the detailed engraving.



Again this system and...

Anytime I have had to service this item it was because the focus stick was sticking. Make sure you clean it very good with every job.

The set screws on the pulleys are probably loose. Make sure you are on the flats of the shafts with the set screws.

A galvo based C02 is the way to do this job if you are in need of speed and throughput. If I had to run this on a flying optic system I would defocus the spot a bit.

Our flash lamp systems are...

Engraving into bricks is done with galvo based systems with exaggerated spots to melt the glass in the clay brick to turn them black. WE do this all the time in our shop. The results you will achieve...

What most people don't understand is what the beam expanded does. We design our universal based cutting systems with the 6 x and 2 " mirrors and 1.5" dia lenses. Our synrad 100 w uses a smaller x...

Now that I think about it that sounds about right if you are working on a large table. My 100W Universal with a 6x beam expander is about that size entering the cutting lens. My table is 48 x 48
...

That is normal and is called divergence of light.

Are you running a poalizer or beam expander?

This happens all the time, also make sure to keep the limit switches clean and watch out for small pieces of acrylic that can get stuck in the belt track.

For those of you looking to purchase used systems we have now dedicated a website to showcasing our inventory of systems we have available.

We are continually getting in new equipment and...

To make a multi k system you will need a lot of engineering and a lot of money. The cost of a multi k system is in the 100K range because of all that is needed. This would not able a very smart...

We cut 1" with our 100W with a 5" lens

No this is not a good idea. you need clean and consistent power. Also, a temperature controlled room is ideal as too hot or too cold affect electronics, optics, etc...

We have done this numerous times with numerous YAG lasers in our shop. You will need a YAG with q-switching. WE have our own software "FLE LaserMark" that allows us to do so and produce acceptable...

Guarding will act as dust shielding as well as air assist on optics and through cutting nozzle. The production models will have tighter look, as stated this is the prototype unit. This was used for...

Yes, three 2" mirrors, 1.5" lens and a beam expander

Please note this is a prototype system. Production units have all required guarding, shutters, interlocks, etc. We have been building machines since 1995 and are extremely well versed in the rules...

To the top!

Ok so this is becoming a very interesting read and I am enjoying it quite much.
Here is what we can offer and let me know if this is out of bounds.
A 4x4 100W (Universal laser tube) Flying optic...
