@allsirius yes, thats pretty normal to switch to the CNC interface when in Laser mode as its then down to the gcode to control the laser using M3 (for on), M5 (for off) and then the S value in each G0/G1 move to control the laser power

@allsirius I'm using more or less the same laser module, probably just another form factor: LaserTree LT-80W-LE-Mini

I first used it with this circuit: https://photos.app.goo.gl/i8Mxxm5eNJhgfwycA
But now I have switched to the one from the wiki.
What is missing in the wiki is the info that this circuit needs a inverted signal.
And according to the wiki page about the breakout board, this is true there as well.
The example to control a servo is: M950 S0 C"!exp.heater7"
So, you probably have to use it like this: M452 C"!exp.heater7" F250

And to control the fan you have to cut the +12V supply to the module.
As dc42 said, you can't use heater and fan outputs. If i recall correctly, they switch the negative side (GND).
So you probably would need a separate relay or so to do this.

@allsirius that are good news!!!

@PCR
The Problem was solved!

And I was able to test the new code form the recommended UltimateRepRapPost..
I see it's working! Now only need to properly configure everything for my machine.
Thank you!!

@tenaja
Thank you!
I did few jobs already with the spindle working passively from the previous controller, all the rest did Duet. And I didn't have backlash problems.
Now I've replaced the spindle on the 3.5kw Chinese watercooled one.
And still have some setup to finish to control it from DWC.
The old 7kw spindle will wait for some more robust machine.
Thanks for answering!!
