Ramps terminal breaking up gcode commands

I'm using a python script in the Code After Each Layer gcode section that is normally sending around 70 lines of gcode to the RAMPS terminal. I know that the gcode injected by my python script works when sent to the printer in another software like Pronterface. However, in NanoDLP the serial terminal shows broken up and segmented commands being echo'd back every few successful lines. I've tried adding delays between each line, as well as including [[WaitForDoneMessage]] and [[MoveWait 1]] between lines of gcode, but neither helps. For example, I might send a bunch of G0 movement lines at once, and the first few echo back and are completed. Then a partial line is echo'd back, or lines are mixed together, and the rest of the lines are not completed.

Here's a reproduction of the terminal output when the error comes up. It generally happens more when many lines (something like >10) are sent at once.

Re: Ramps terminal breaking up gcode commands

This was tested both on the latest stable build, as well as the latest beta build of NanoDLP. Additionally, a lower baud rate was tried, with no difference.

Re: Ramps terminal breaking up gcode commands

Try add in middle see if it does help.
[[Split]]

Seems serial communication issue.
