You are probably right, it comes from the SD card.
Since the last message, I focused on complete reconfiguration of the card with your documentation.
I installed the latest version 3.01RC9 of the firmware and check all the lines in the config.g file.
The motors, heaters etc are all well configured and the axes are really precise.
I changed the SD card to an 8GB Class 10 HCI EMTEC.
But the problem I arrive at the same result, during printing the printer stops! A message (from the new firmware) informs me that it cannot read the SD card.!
