Laser Add-on
i have an engraving laser and i see that you can enable the laser option on the firmware.
so am i right in thinking i can have a 3d printer that will also engrave?
or is it one or the other.
as i have my laser fitted and connected to digital pin 5 but can't seem to get it to turn on

What's voltage required your laser?
If you connect the laser to D5, i assume that the laser is powered by a TTL driver so you connect just the signal to RAMPS, right?
How are you trying to turn on the laser? With a Gcode o manually?
The laser will powered on ONLY with a G1 gcode command, if you previously set the laser output power...
i connected the power to a separate power supply as i didn't know the power consumption so i set the voltage to 5v and tried to get the laser on by entering the following G-code
but all i get is the head moving about and nothing else
So, maybe 5v are not enough to power it...
Usually there is a label with the model on the laser, find it so you can know some spec of it...
Can you also provide us the configuration.h ?
So we can check that you have correctly set the laser output port...
Load the configuration.h in the online configuration tool and enable it, and choose the output port...
In your config.h the laser feature is disabled...
so how do i tell the software i want to use the 3d printer then after engraving the model with the laser. can this be done in one program?

M450 tells you the mode and
M451, M452, M453 selects the different modes.
I just have a FDM printer so I cannot verify this.
I have the same Laser unit, that is powered by 12v and used TTL/PWM to control the power.
Was reading previous posts but still a bit unsure on the connections.
I searched for documentation but can't find much specially on the connections.
To where should the TTL/PWM be connected? So something like the extruder fan pin?
Than in a printer is a PWM output right?
