Template to identify correct settings for materials?

Post by Sanjay Vakil » Thu Jan 05, 2017 10:01 pm

I find myself tuning the laser to each new material I work with: wood vs. ply vs. MDF/ply vs hardwood.

Does anyone have a standard file that walks up power settings/speeds to find the right combination for a clean cut with minimum burning?

I'm imagining something here like the test page a printer would spit out: a collection of tests vector images with the settings next to each. And if we're doing that much, we might also want to nail down the range of settings for raster work as well.

The idea would be to run it on a small piece of the material before you do your bigger cuts/engravings.

Does this exist?

Would anyone find it useful?

A list was started in a thread on these forums but people did not continue to particpate after the first few days it was up.

gene has made a file that is exactly what you are searching

http://rdworkslab.com/viewtopic.php?f=39&t=743

you can use it to test engraving from 10% to 75% in one file, and if setting all colors from "scan" to "cut" you can test cutting also.

you will have to tune the speed according to your machine power.

i don't know a file that test simultaneously with speed and power both changing (would require a lot of colors in rdworks...)

I think that you will have to run cutting and engraving tests on each material for your individual machine and power. Keep in mind that once you have a power/speed setting that works well you can save the setting in the Para library. Gene

Thats Great! thank you, do you have one the does smaller increments? starting at %10 and increasing power by %2 each test color, for fine tunning engravings

Jared, if you're the adventurous type, you can edit one of the stock templates to meet your specifics. I suggest that you open a suitable base template, then immediately use File, Save As, to give it a new name representative of your objective.

Change the text in the fields and adjust the power settings appropriately in the column of colors in the right side. Once you double click on the entry in the color column, you can change the settings for that color, then change color in the left column and move down to cover all the entries in one fell swoop.
