MPCNC, RAMBo, Laser - Output for turingin off a relay at end of job


I am looking for advice on what output that can be used to operate a 12vdc relay at the end of a job.
I use am currently using a diode laser with my Burley MPCNC running Lightburn software.

In previous posts (for use when I was using a router) it was indicated that the Fan 2 output could be used and I will use the Fan 2 output but I am unsure as to how to trigger this output with the Lightburn software at the end of the job.

Any advice will help
