Output, Show and Hidden Layer Surprises
A visible object does not automatically mean it will be sent to the laser, and an output-enabled layer can contain geometry you forgot about.
Minimum Power, Slowdowns and Corner Behavior
Some controllers expose minimum/maximum power behavior that changes output as speed varies; do not assume all GCode, DSP and Galvo devices interpret minimum power the same way.
Perforation Mode: Dash and Gap Without Manual Segments
Perforation Mode turns continuous vector paths into alternating cut and gap segments, useful for tear lines, fold guides and decorative dashed cuts.
M3 vs M4: Constant and Dynamic Laser Power
On GRBL laser-mode workflows, M4 dynamically reduces power as motion slows, while M3 is constant-power behavior; device type and $32 determine whether M4 is valid.
Air Assist in Layer Settings and Real-World Cutting
Air assist can improve cutting and reduce flame/soot, but software control only works when the machine hardware/controller supports it.
