Hello!
Yesterday I did a lot of searching and RTFM.
But now I’m stuck.
I got a chinese laser 2.5W. Flashed Grbl 1.1f and installed Laserweb3 on my surface.
I had problems with turning on the laser. Mana SE board with Nano Ardunino. But right connection (D11)[1], which works out of the box. No soldering for me.
After that I set up Grbl as stated on the Wiki [2]. With some tweaks it works now.

But I have to set Laser Power to 1000. Then it cut through normal paper. But I use cardboard it won’t cut it.

$30=1000 and this value is also set in the settings in LW

Can I go higher then 1000 to get more out of the laser? I’ll try some values during the day.

Thanks for any help.

Version: LW 30552(Git); Grbl 1.1f

As far as I understood this is the percentage of the maximum power, the laser can output. Setting the power is done with a PWM controlled current. Which means that you can not exceed 100% but set it between a range of 0% and 100%.
The $30 is the resolution between 0% and 100%. My Eleksmaker board uses GRBL and can do 256 steps between zero and max power for the laser. I had read that a smoothieboard can do 1000 steps, which should come handy with reproducing greyscales.
If you use GRBL you should set your value of $30 to the resolution your hardware can handle and also set the PWM Max S Value in yout GCODE settings of Laserweb to the same number.

More experienced ones please correct me, as this is just what I understood until now. And also this is giving back a little of the help I already got here :slight_smile:
