Do you mean you’re sending the laser on rather than laser off command? I like to think that I have a fairly logical mind, in fact years ago I used to work as a programmer. So I’m having a hard time wrapping my head around why the pause command’s effect is virtually instantaneous. Motion stops, laser turns off. If you can supersede the buffered commands to shut down motion and burn, why can’t the resume command supersede the buffered commands and restart the burn as soon as motion is restored. Sorry to be a pain in the neck. Just trying to understand.
