Laser is fires immediately after UCCNC start

[andileibi]

Hello experts, I got an 80W laser https://lasertree.com/products/10w-optical-output-power-laser-cutter-module?variant=42608494215319 for my Stepcraft D2 840 control software UCCNC.
As soon as I start UCCNC, the laser fires immediately with 100% power, and I first have to deactivate the laser with the M11 command, so the question is, is there somehow a setting that the laser is deactivated after starting the UCCNC
UCCNC settings and connection diagram see pictures.

The laser should not be powered up before UCCNC is running. That is the only way it is 100% safe.

Thanks for the quick answer, even if the laser is not powered when starting UCCNC, as soon as the laser receives power it fires.
The best thing would be if the PWM output is deactivated (code M11) when starting UCCNC

some of the lasers use no pwm as full power. then reduce up to full pwm. so that would not work.
you control this with your m3 command which powers up the laser.
