Help with laser not firing

Drizz1le

Hi everyone,

I need help with my laser not firing. Im not sure what the issue is, wether it is hardware or software. My laser is plugged into the "laser" port and I have gotten it to work in the past but then I took a month break and came back and I'm not sure what the issue is.

My laser is 10W.

Below is my config file. Can someone tell me if im missing something and what commands to test it?
I tried turning it on with "G1 X50 S180" but it does not work.

Thank you

@Drizz1le What firmware version are you using?

You don’t appear to have a tool defined, which you need, as it says here: https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_laser#firmware-configuration

Add this to config.g:

; Tools
M563 P0 C"Laser" ; define laser tool
T0 ; enable laser tool

I’ll make that a bit clearer in the wiki.
