@gaou I haven't ever use a LASER, but maybe THIS page can help you figure it out.
thanks for replying . this page is for the newer versions of duet so i dont think it is suitable for my duet.
for now i need only to fire it up and no control over the power.

OK, Since I don't know anything about your system, I'll make another blind suggestion: Do you want to update the firmware on your board to get closer to the latest features?
UPDATE process for a 0.8.5.
Someone else will probably come on who knows more than I do so maybe you want to wait for that advice.
-
What firmware version are you currently on? The latest firmware for that board is 1.26.1 I believe.

yeap this is what i am using....
edit: i still cant get the M571 to work, although i send a M106 P0 I-1.

What is the syntax of your M571 command?

It is "M571 P0 S1". but i ve read that since there is an M452 in mt config an M3 is the proper command for getting the laser on. I am very confused...
-
M452 would be more desirable if your firmware version supports it. Which I'm not certain.
What happens if you send M452?

i am sending M452 and didn't got any responce. I have a m452 in my config file .

Looking at the release notes it looks like M452 should be supported farther back than 1.26.1
So what is the syntax of your M452 command?
With access to laser mode, you wouldn't need to use M571 anymore as long as your laser gcode generation software can output G1 S commands to set laser power.

M452 P"FAN0" S1 . i also tried P0 instead P"FAN0"
please keep in mind that if i send M106 P0 S255 the laser fires.
-
I believe with your firmware You'll need to use P# where # is the logical pin number being used. "fan0" would be for RRF3.
Now we just need to find the logical pin number of Fan0. And then G1 S1 moves should enable the laser while moving.
I think it should be P20 if I'm reading this table correctly.
M452 P20 S1
-
if i send M452 p20 s1 the firmware says "bad p parameter"
Delta Printer || Duet 0.85 || firmware 1.23
Laser K40 || Duet 0.85 || Firmware 1.26.1 || Web 1.22

I've played with diode laser on older RRF versions, but never use M571 or M452. There was a plugin raster2gcode and others in inkscape, that allowed me to use M106 P0 Snnn to switch power on and M107 (or M106 P0 S0) to power off.
What concernes me are the high currents you run your 40W? laser tube with. I'd never go above 12mA, better stay around 10mA for cutting. -

What concernes me are the high currents you run your 40W? laser tube with. I'd never go above 12mA, better stay around 10mA for cutting.I keep that in mind but i would prefer to do this by the lightburn way....! I was thinking of writhing a macro and change the gcode on notepad++ .
I knew that inkscape can write gcode for the lasers but because of my job i am very addicted to lightburn that comes with the big lasers. I am so addicted to duet also....! ANyway this is probably the way to go and thanks that bringing this up...I cant remember what exactly was the power range of this tube and it is the second i own ( sold the first) but during the tests i am using a test resistor that is intended for that job. it can stand up to 100w power ..
Thanks a lot for replying.

Sorry, I think I may have been looking at the wrong logical pin number section.
Here's the one for the 0.85 board. Which of those listed pins are you using? Keep in mine, I have zero familiarity with the older pre-Duet2 boards.

https://duet3d.dozuki.com/Wiki/Using_servos_and_controlling_unused_IO_pins#Section_Duet_0_6_and_0_8_Num_5i cant understand how are these connected to fan0 . all of these seems to be at the expansion header.

Yes I'm not sure either. I'll check.

So P20 is correct I think, but we may have missed the important step of freeing up the pin first by disabling the fan with
M106 P0 I-1. So give that a try. -
