After al the software updates and installs i dont have any error msg in laserweb anymore, i can move all axes, but fire the laser stil doesn’t work. Just messured the fire pin on SB, it switches between almost 0 and max 3.3 volts (M3 M5), i wonder if thats enough to fire the laser itself?
yeah thats correct, 3.3v is the logic of smoothie, our PSU will work with it.
How are you test firing? I had not got to that part yet.
The laser fire button in laserweb does not work as we need to be moving to fire.
You want to create a macro which has this g code.

thanks for @Krijn_Schaap for that idea 
Could it be the TL/TH pin issue that I had @Bonne Wilce? Or was that just my mistake? 
Could be, easy to do.
The fire pin needs to be in the TH port which the the furthest right one
