Repetier wroteThe image from display shows a serious error with temperature handling. Can't say how marlin handles this e.g. go into some halt mode and do nothing. In that case communication would also look like that until reset of printer.
Sending multiple commands to marlin works also the thread says at one point it does not. You just should not exceed the input buffer size. Alternatively enable ping-pong mode and only 1 command will be send at a time with the price of slower communication (also normally still enough).
It should not depend on the model, but if it is the error state shown on display that can be the reason and if something in the gcode causes it (here temperature too high) it might explain it.
That character display does not use serial2 at all so it is not needed. Thought you were using the TFT display that often comes with that board. Still having only one serial is good especially since you are not using the other one.
I use #define REPRAP_DISCOUNT_SMART_CONTROLLER
But now i comment it.
Where can i enable ping-pong mode?
