Did not see this addressed in the last to gsender releases still, and I know some other folks have the same issue with leds not turning off, changing color etc on the rail line.

See a post about possible length to first pixel issues, but no followup from Scienci on that.

Mine turn on white, never turn off white and maybe blink once when a job finishes, but it’s once and partial second length so you have to be pretty much paying attention.

@arw01 As this has been discussed on the forum for quite a while, without, it seems a firm resolution, I suggest that you open a support ticket with Sienci.
