Error using "G-code keyboard"

[Jeroen1278]

Hi there,

first of all great project.

But i have a problem. I am using a arduino mega, ramps 1.4 board and a nextion 4,3 screen. Almost everything is working fine. Except when i use the "G-code" keyboard. I can type the command and send it but when i look in my serial monitor i get a "error":

Echo:enqueueing "e: " Echo:Unknown command: "e: "

And nothing happens on the machine. Other commands like homing are working fine. Below the output of the serial monitor from my arduino IDE.

Does anybody knows a solution for this. Thanks a lot.
