Speed in Test Material

LightBurn Software Questions
1

Hello,

to begin with I have to say that I only started using LightBurn yesterday.
I tried TEST MATERIAL, I have automatically extracted data from the laser (speed, power, etc.)

I have a question about the speed setting in the material test.
I tried the LaseGRB app before where my engraving speed was around 10000mm/s with 50% power.

But here in LightBurn I get the same results at 10mm/s 50% power.

So my question is: Does LightBurn use any speed conversion?
Since the manufacturer indicates a recommended speed of 12,000 mm/s.
-In LaserGRBR I understand that the deviation of 2,000 can be understood depending on the material, but not from 12,000 to 10 mm/s in LightBurn.

  • In short, I don’t know if I have something wrongly set somewhere, or if I have to somehow correct the manufacturer’s speeds, I looked at various videos and settings - even here on the forum and I couldn’t find an answer that helped me.
  • the setting of the maximum speed of the x and Y axes is correct according to the manufacturer’s description (x 25,000 / y 18,000)
    -The laser speeds up and slows down, the test of the material takes place as it should from small values to larger ones and does what it is supposed to do - only the speed is in the range of 10 not 1000.
  • of course I don’t know what the real speed is when moving, I have no way to measure it.

In short, my question is, if the manufacturer recommends a speed of 12,000 and a power of 50%, how do I enter it here so that it corresponds and I didn’t have the speed set to 10mm/s?

  • It is clear to me that with the help of the material test I can make my own table with speeds and performance, but I have to start from the beginning, because the recommended speeds are completely somewhere else.

I think you are confusing mm/minute with mm/second. Both units are used in laser world, and LB has a selection for default use in Device Settings.
10,000mm/s and 12,000mm/s are pretty darn fast, good luck with that machine :slight_smile:

Check 10,000 and 12,000 are not actually mm/MIN rather than mm/SEC.

Yes,
sorry you are right a misread the mm/m for mm/s.

  • that make sense now i just read mm/… and was thinking is the same I dont know thal lasers using both.

But Im looking to setting and dont see any choice to switch mm/s for mm/m.
It is Machine seting or Device seting? (for developers in our language (czech) you have both names the same, but there is obviosly diverence betwen these two)

Or do you mean this?:

Thank you

Edit: so it was this… Im sorry for troubles > but i was thinkint this is just the unit of the grid on the working place( not for all seting) so there is still defaul seting for me. I switched to mm/m and all is OK.

Thank you again for help…

mm/sec and mm/m are both on the top line, those groups are just general you can use ANY of those settings for either type of laser.
