Two Duetboards in standalone mode on one Pi

Hi,

I'm currently struggling with a problem I don't understand. I hope you can help me. It looks like the communication buffer is overflowing. But I don't understand why all of a sudden. Both printers worked before. Unfortunately, I don't know exactly when the error appeared. Whether it was after a firmware update from Duet or Repetier.

    If it is overflow, we did not change anything related to that. We limit the amount to what you defined in connection settings. However, if the firmware has reduced the buffer size this will cause an overflow. So first thing to do is reduce the buffer so it does not overflow or even go back to ping pong mode where no overflow can happen for the price of slower communication. When you set up the firmware check how big the input buffer is.
