Setting up first time with grbl. Laser moves through pathe but never fires.
On some engraver heads there is a small power switch to enable the laser.
Please confirm that the laser head is powered. You should see an LED and a cooling fan running.
In LightBurn, near zero power operation can occur when the Smax is not identical to $30.
In LightBurn, open the Console window and type the following:
$$
then press enter.
Copy and paste the report generated into a reply here.
Then click Edit then wheel down to click Device Settings (wrench/screwdriver icon) and have a look at the Smax value on that pop-up window. (lower right).
If you’re using LaserGRBL instead of LightBurn you will have to reach out to them for support.
