China Laser 500mW not work

should I set all value´s to 255?

Better to set LightBurn to 1000 if your controller is set to 1000. That will give you a little bit more precision.

O k thank you, I test it tomorrow.:slightly_smiling_face:

it is the same Problem

ok

  • You do not have Laser Mode enabled ($32 should be set to 1, not 0)
  • Your maximum speeds are 500mm/min (8.3mm/sec) - $110 & $111
  • Your acceleration values are painfully low ($120 and $121)

You should read through the configuration page for GRBL about the settings I listed above. You can find that info here: https://github.com/gnea/grbl/wiki/Grbl-v1.1-Configuration#grbl-settings

hmm I looked for that, and changed it but its the same problem.
have a look…

What settings are you using for the cut you are trying to run?

Wich setting do you want?

I can see the speed and power values, and those were the ones I wanted most. How are you determining that the power is weak?

Can you also show me your device settings window? (go to Edit > Device Settings)

I can see it for the intensity from the laser Light.

I’m interested in this specific value:

sorry

I can’t see anything wrong with the settings as you have them now. The reason I asked how you were determining that the beam is weak is that your laser is only 500mw, which is not very strong.

If you are comparing to how it worked before, or how it works in other software, there might be an issue with the settings or the generated g-code file, or possibly even that the hardware is damaged.

If you are simply saying that the beam is weak, but aren’t comparing that to anything else, it might just be that your laser is weak.

with the china Software he run with full Power, I can see the different.
In the first of starting the Laser he had a minimal Laserpoint to focus the Laser.
If I started the LightBurn and conect it, the Laserpoint run with more Power.
But it is not so mutch Power to burn something, maybee 15% or so. That is all what I can say.

Does the provided software have the ability to save the GCode, or see the commands being sent to the laser? If so, attach a gcode (text) file here so I can have a look, and also a simple one from LightBurn.

Yes the “Engraver Master” provided Software has an ExportNC File Buttom.
Test RawIsland-Engraver ExportNC.nc.txt (93.2 KB)

This part is important. I need to compare with what LightBurn is generating with your settings.

That tool isn’t using the M4 command. Change your LightBurn device type to ‘GRBL-M3’ and it will produce very similar gcode output.

hmm I change it but the same issue.
