J Tech dual pro 14w laser not firing?

1

Hi All
Newby here, just installed the J Tech 14w laser to my Onefinty CNC, I’ve followed all the video’s but can’t get the laser to fire ?
The fans turn on and I can get it to test fire by turning the switch next to the two green lights on and off, i have tried resetting, but no joy.
it does not respond to any of the M3 S10 commands all the way up to M3 S100
if trying a G-Code made up in Lightburn the Onefinity goes through the motions but no Laser.
the firmware on the Onefinity is 1.0.9
Am I missing something ?
TIA
Peter

s100 is only 10% fire rate.

Try s1000, that is 100% fire rate.
