So I got this LCD adapter with Sd support built in. Great, configured it in Repetier firmware and when I insert (any) sd card it slows the screen down to a crawl and half the time won’t register navigation with the rotary dial.
I open Repetier host and try to connect, it registers there’s an sd card then says SD init failed.
Any ideas? I’ve tried the sd detect pin in the firmware as -1 48 and 53 the cards are all formatted fat and under 2 gigs.
