Do you have the "Halftone" setting set to "Colour"???
If you don't then you will get exactly the scenario that you have described.

I had a 4" lens mounted in the 1.5" lens carrier and made a custom focus tool for my Speedy 400.

It works great when engraving parts where the engraved area is obstructed by nearby walls (high...

It will be slow but you should be able to cut 1/2" plywood with your 100w laser.

The issue you are having could be one (or both) of two issues;
Misaligned optics - this was mentioned...

Alder, Cherry, Maple, and Baltic Birch plywood.

I cannot believe it has not been mentioned yet but a "Dust Buster" (or similar hand vacuum) is absolutely indispensable.

CorelDRAW imposition layout.

There are several videos by Carl Brewer. You don't need to buy anything else it's a native function in CorelDRAW.
Do a search in YouTube.

I engraved a cover plate for a "performance gift" given to a very famous singer.
Unfortunately the NDA doesn't allow me to say more than that, but I do have a copy of the plate in my sample box......

The time to create the video is now when you do not know what
you are doing so you will not take it for granted what we may or
may not know. You now know what you didn't know, when you ...

When you ask too many or the wrong questions all you will hear is crickets.
(try asking someone on the forum for the drawings for a one-off project sometime.)

Sometimes the clients bring ready to...

Most of my work is as a cutting service. I also have a laser and the projects are quite diverse.
I cut stencils for football fields, stencils for SMT (surface mount electronics), and...

I have just taken receipt of a brand new AXYZ 4008 CNC router with 7 position ATC, 8.5 Hp

(I) "get a nice dark brown dot on all the mirrors". Your mirrors are discolouring when the laser beam hits them?

It's not a laser but a high voltage / low current device very similar to an "electric fly swatter" in operation. The leading wire is charged with a high voltage and it grounds back to the base of...

If your only consideration is engraving speed and your maximum engraving size is 12" X 12" (or less) then you are barking up the wrong tree. For the fastest engraving speed in a limited size no...

I mix a wee bit of dihydrogen monoxide in with my Scotch. I like living close to the edge. :P

It very much depends on the artwork.
Line art with no fill, vector.
Fills and gradients, raster.

Yes, the Kern control software has more controls than Trotec, Universal, and Epilog. Start delay (pierce) and power ramping / speed on corners are two of them. They are there to help make your parts...

Looks like a 21st century 1950's hair dryer. :p

I think the sonar focusing will be less than useful for the textiles I cut.
As for using standard size materials a 24" X 32" bed would have been very much more useful.
Other than that it looks like...

If you have to engrave everything two or three times just tell your boss how much time is being wasted, product scrapped because the laser is naf. If they have half a brain you will be working on a...

One thing you could do is print the decoration onto tissue and then imbed the tissue in the finish. With the proper tissue the tissue disappears and the decoration remains. One thing you need to...

Regardless of the beam shape, if you have the power focused on a spot 0.006" in diameter it's power density (W/cm^2) is 44% lower than the same amount of power focused on a spot 0.005" in...

Keith;

I don't want to be alarmist or anything but if my spot size is 0.005" and yours is 0.006" then if we had the same power then your power density would be 44% less than mine, i.e. the area of...

I don't have a set of feeler gauges but I did cut a 1" square and the difference between the piece and the hole is 0.010" so the kerf is 0.005".

How are you measuring in Microns and...

Bert;

I'm sure that your machine can achieve results very similar to what I am doing but you will need to spend some time and effort and burn lots of material experimenting to get there. A good...
