Hey Tom, hey all,
the “Router” and “Laser” options were introduced with firmware 1.0.9. They are internally based on the “PWM spindle” selection which you had to choose in older versions when using a laser or a router on a relay.
You may have noticed that for both new entries much less options are visible than for “PWM spindle”, but these options are invisibly still present and are automatically set by the default configuration. Thereby the entry for the selection “Router” internally implies “rapid-auto-off”: false while the selection “Laser” implies “rapid-auto-off”: true.
