Laser intensity

lucasss

Hi,
I'm trying some Inkscape's plugin for convert an image into gcode...
But some plugins change the laser intensity with the command:

M03 S*

Does repetier support laser intensity with this command?
If yes, from which value? Because I'm try some gcode and:

M03 S60
M03 S10

etc does not turn on the laser...

Thanks...

Edit:

Yes, repetier support laser intensity...
With "M03 S200" laser turn ON.

So there is a threshold...maybe the 50%...so maybe the minimum value is 128?

No, you just can switch ON and OFF.
Values >199 switch Laser on
Values<200 switch Laser off

oh...

There is the possibility to add the laser intensity?
Maybe i have to edit drivers.cpp?
Something like this should work? My laser is on HotEnd 0 output of Ramps...

#if defined(SUPPORT_LASER) && SUPPORT_LASER
uint8_t LaserDriver::intensity = 255; // Intensity to use for next move queued if we want lasers. This is NOT the current value!
bool LaserDriver::laserOn = false;
void LaserDriver::initialize()
{
if(EVENT_INITALIZE_LASER)
{
#if LASER_PIN > -1
SET_OUTPUT(LASER_PIN);
#endif
}
changeIntensity(0);
}
void LaserDriver::changeIntensity(uint8_t newIntensity)
{
if(EVENT_SET_LASER(newIntensity))
{
// Default implementation
#if LASER_PIN > -1
analogWrite(LASER_PIN, newIntensity);
#endif
}
}
#endif // SUPPORT_LASER

for shure you can modify refer for example thread " laser section" for some informations.for modification best solution is to use custom Events as it makes future updates easy
