Not sure if. Printing over sd card bypasses information flow so you can not trust shown values like fan or position any more. Also printing time prediction becomes unavailable. Maximum possible is percent and prediction on passed time, which is completely different. These are the reasons we omitted sd card print.
Have you already selected to reconnect after a connection lost and continue print? Especially on raspberry pi this is a saver as it mainly disconnects there due to power problems. Was especially added for this.Problem with sd card may be that we need to prevent reconnect when sd was running to prevent a reset. But that is solvable as well. I mean bette rnot connect with message because of sd print then a reset while sd printing.
