Some Fun Facts to Help With Your Settings

If you just came looking for some settings, you will find them listed on each
of the projects posted on this site. I do hope they work just as well for you!

This page is for those that are tired of burning up time and product
chasing that golden setting that just doesn't exist. Sorry, but it doesn't!
The settings you do find will get you close, but more often than not,
you will be back to experimenting, wasting more time and product.

How can this setting work so well for them, but not work for me?

Sadly, there is no one golden answer for that one either..
There are a number of variables that I haven't seen much about
that may have something to do with it and worth investigating more.
Some basic things you may want to look for when out hunting for settings.

Before I go too far, I should tell you a little about my background. I have been an machinist, welder and fabricator among other things, and have been exposed to a wide variety of tools and materials. There isn't an industry I have been in that temperature, humidity and the environment in general haven't played a key part in the outcome of the product. If a huge machine will act different on one day than it does on another because of a humidity change, wouldn't that effect this tiny laser or the materials just as well?

Sure we have heard about one wood having more moisture than another, but what about the moisture in the air or just the general environment? Could this explain why one persons settings won't work for another? The settings of someone in a controlled environment using materials that have been acclimated to room temperature are going to get a different result than someone out in the damp cold garage using materials that have been accumulating moisture and probably colder as well.

You may already have all the settings answers you need.
You just needed a different way to look at them.

Go back and look at the places you got settings from and look a little deeper. How similar is their work environment to yours? You will find that the people you got settings from that worked, have almost identical work environments. The one or two numbers their settings are off may be due to it raining or just having the windows open or something. I'm not going to say one environment is any better than the other either. Sure it may be more comfortable in the warm house, but what advantages material wise are you missing out on?
The same may go the other way as well. What kind of things are people working outside missing out on?

This could also explain why your own settings won't work sometimes.
But it worked just fine last week!!

Was it raining? Heat on now and A/C was before? May be things worth noting with your settings.
I just think there is more to it and it is something I will be testing and watching a little more closely myself.

At the same time, if you look at this another way,,, This could be a good thing!.
We do know that temperature and humidity/moisture do effect different materials in different ways..
Would a stainless cup from the freezer frost enough to engrave on
and would it take any better than a room temperature one?
Would a stainless cup heated in the oven take engraving better?
Heat expands metal. Maybe it would open the pours and would take the engraving.
Just a few more things to experiment on. Same goes for other materials.
What other secrets are still hiding out there?
We have just started this journey.. There is more to be found..

Bullshit you say?
I don't make statements without being able to back them up.
Have you ever heard of anyone shattering glass with a diode laser?
Hold my beer..



At 9sec a piece of glass shoots off the top.
At 16sec you can here the laser start 'arcing'. Making a weird noise.
At 28sec you can hear the glass break again

This is the same piece of glass I just ran a few tests on with the same settings.
Everything worked great and was doing a verification test when this happened.
Nothing had changed on the machine and using the same materials. What happened?


Here is the whole story! You will laugh at what it actually was.
I rotated the piece to the clean side and lowered the settings from 100/10mm/s down to 90/20mm/s and tried it again. It cracked a bigger chunk off this time.. I rotated the glass again and lowered the setting to 80/30mm/s and it cracked again. The D1 head was making a weird noise also and prayed it wasn't going bad. Went to pick up the piece and noticed it was freezing! What? I'm in the house, everything is at room temperature and has been.. How can this be? Then I had the Ahh ha moment!! I had changed how I was washing the glass after engraving. I was dropping them into a tupperware tub full of water and letting them soak a little while. Works great! I had set this glass in there and got busy on other things. It had sat in the water most of the afternoon and it was freezing cold!. When the laser hit the cold glass, pop it went! Tried another glass and all the old settings worked just fine. There IS more to investigate and try. Next step for me would be heat a piece of glass in the toaster oven and see what happens.
Film at 11.. lol
