Hi Just an idea, not a real need (but it can be fun, and i will use it for sure) something like a led_mode=blink for .NGC with associate parameter blink:on:100:off:300 for time in ms for each led state? or defined time with 2 value map or just 3 "blink" predefined mod, blink_slow, blink_mid, blink_fast Anyway, the idea is to have a blinking led function when led is on, because a NGR script (set led and delay) is stopped a soon as another section is called Best
