laser on

[ronisegoly]

I have laser module
Connected to CNC machine
I can connecto the module from lasergrbl SW, jog the axis and load file
But I can't turn laser on/off by SW
If i use physical button it will be on but all the time of course so can't really engrave
Any idea?
Tried m3 m4 and laser flag 0 and 1

Do you have this enabled?

[ronisegoly]

Yes, I tried check and uncheck
BTW not sure it's related, when I connected the laser module I was left with one cable which was not used
See attached

I think that lead is for if you have the 3 pin 12v, Gnd, PWM socket on your main controller board.

[ronisegoly]

the socket on my controller is two pin
what's the functionality of the PWM connection aside from setting laser on and changing it's level? If that's the only one then I suspect the connection is faulty

[StuartB4]

The 3 pin PWM wire supplies the power and the PWM signal to a 3 pin laser, but your laser has a seperate power supply, so from what I can see on the images you have what you need with the seperate power and the 2 pin PWM lead. The black wire is just a ground on either the 2 pin or 3 pin lead.

[StuartB4]

The only other thing I can think of is to ground both power supplies together.
