Just got my Rep 2 upgraded to the newest Sailfisn. It is excellent. One thing i noticed wasn't in the firmware (or at least i couldn't find it) was the ability to turn the lights on the machine off during the print. This would be most convenient because I print in the same room that i sleep and the light can be very bothersome. I became very accustomed to turning the light off and going to sleep. If its there, let me know, if not, FEATURE REQUEST! Thanks!
