Hi gregstah,
the "maximum open file count" error is fixed with the newest firmware which is just released about an hour ago.
If the print ist getting bad, I pause the print an then reprint from SD card. I only additionaly zero the Z-axis again.
Restarting the print in Pronterface is not possible yet (see some Pronterface issues
here )
