The way that Prusa i3 communication?

Would like to ask guys

At present, I installed the prusa i3 with lcd screen.

I can select functions directly from the lcd to control the machine.

Before install lcd screen,I use Repetier-Host to control printer's motion.

I would like to know the way that between the computer or under the lcd instructions to the machine

these communication is how to proceed?

Because the 3d printer code review on the network are focused on how to set the trajectory and machine parameters

about communication interface is less information.

Because I want to use arduino to communicate with the pc (using serial monitor)

Want to enter some simple code directly to control the motor to the desired location

So need some communication information about how Prusa i3 communication work and just need to focus on

how motion instruction is send to pc and let motor move.

Big thanks to everyone!

I think the reprap-wiki can help you, there is a list of all Gcode commands and examples how to use them.

To move a motor, the printer needs to be "homed" first with G28

Then you can use G1 F.... X... Y... Z... to move each axis.
But I recommend using pronterface or repetier host, like you did before.

Thanks to reply~!

But is it possible to control motors by using serial monitor which on arduino IDE directly?

Yes, you can type in the gcode-commands and send them to the printer.

Got it ~

Where can i modify some codes to let the printer know what g-code I type in on arduino IDE serial monitor?

It seems in the Marlin_main.cpp?
