How to turn off all Air?
In order to color my engravings using metal powder I need to turn off any air blowing/venting/...
The technique I want to use is engraved->out powder (without moving material)->engrave again with low power to melt the powder.
Turning off Air Assist is a no-brainer, but some other air venting is still turned on (using Lightburn), so when the head arrives in the area I want to engrave, a lot of the powder is blown away :-/
