How to solve SD card reading problem
I'm trying to use Repetier firmware on my milling/engraving CNC3018. I use Arduino Mega 2560 R3+RAMPS1.4+RepRapDiscount Full Graphic Smart Controller. Just today I've compiled first Repetier firmware and load it into hardware. Preliminary testing is O.K: steppers run manually from encoder, LCD is O.K. The problem is SD card reading. It writes, "LCD inserted", but any file (8+3 named) is not visible. This SD card works good in my PRUSA I3 (Marlin Firmware) printer. I tried to format SD card FAT16, FAT 32, but also without success. Would you please help me to solve this problem?
