So i have the full graphic display, all looks good, but it has to be powered via usb for that stuff to work. so what the point of having the sd function of the graphic display if it has to be powered with USB? is there a way to run it without usb? want to try and make it standalone untill i get the dedicated pc setup for it.BryanParticipantNovember 6, 2015 at 10:15 amPost count: 58
It should work without USB. What are the specs on your PSU? The LCD unit will get power through the 12V/5A connection that also powers the stepperskarltinslyParticipantNovember 6, 2015 at 10:33 amPost count: 279
I have the older 20×4 LCD. Powers directly off the RAMPS. I usually don’t have computer connected to my CNC, though I wish I could get this FlashAir card working, to make it easier to send files to it!
