Set of 3 Gradient Charts on one piece of material

Hi there,

I wanted to share the gradient charts i’ve created, because i find them extremely useful. They are set to be done on an A4-sized material (297x210mm) but you can of course resize them as you wish.
You will find all charts in Lightburn format herebelow.
Speed and Power values should be ok with most of the recent machines, like X-tool, Atezr, CO2…

As you will see, there are 3 charts + 1 extra.
The first is for the line engraving, second for filled engraving, and third for plain cutting.
The extra is also for cutting, but includes portions with two and three passes.

How to use : simply load and run one chart at a time, leaving your material in place until you’re done.

Load the 1st chart, adapt as needed, and run the job.

Don’t touch your material, load the 2nd chart, and run the job.

Again, don’t touche the material, load the 3rd one and run it.

Which will leave you with a nice piece of material with all those 3 charts on it, making it quite handy for quick reference :

Notes :

No chart goes above 80% power. This is to save laser’s lifespan.
I’ve set up the charts in mm/s because i use both a Gweicke Cloud CO2 laser and an Atezr P20+ diode laser (which can reach utpo 400mm/s). If you prefer them to be in mm/min, just change this in Lightburn’s Options ; calculations should be done automatically for every layers.
For the CUT chart, i made two : one is with a single pass from start to finish, and the second one includes portions with 2 and 3 passes (as per the above exemple, the MDF picture). This can be useful for thicker materials.
