JGMaker is having a CLEARANCE sale on the commercial-grade Z-603S -- at a BONKERS $399. If you're in the USA, and want a ready-to-go full steel frame printer... run, don't walk! ⏩ JGAURORA Z603S CLEARANCE ⏪ Only 4 units left!

A5S LCD powers on with USB connection

With the printer's main power off, the LCD menu will power up, and function, when a USB cable is attached.

I just want to make sure this is normal operation, since i've read a few comments about stray voltage being an issue via USB on the A5.

If this is normal, will the screen go to "sleep" if I leave it plugged in. My hope is to get Octoprint running, and I would like to leave the USB plugged in, but I would rather not have the LCD constantly powered. 

Thanks for any help.

    Hi Geoiv, yes this is normal behaviour on the A5S. Octoprint should work with the custom firmwares on the A5S. The LCD is directly controlled by the motherboard on the A5S, unlike the A5 where it is a separate module with separate firmware. A sleep function on the screen would be nice, but not implemented yet.
    Thanked by 1GEOIV
