Customizing Printrun & Pronterface GUI: 2 serial ports

Hi!

I'm hacking together two delta printers running Marlin
Into a unique art robot, and I'd like to be able to
Customize the Printrun interface so that there are two
Serial ports open in the same instance of the application.

I know it is possible to edit the GUI to create custom buttons,
Or to add an extruder, but it is unclear if what I want to do is possible

Ideally I'd press one button and it would send a G-code macro to both printers at once

I've written a custom python script that can open up two serial ports
And send each a command, but I'd like to take advantage of the Printrun
Interface, If possible, rather than having two windows open, which is how I'm doing it now.

Thanks in advance!

Your Welcome!

If both Deltas always get the same macro, you could send the data to one serial port on the "Master"-controller and the master echoes the code thru another serial port to the slave-controller. IIRC there are 4 COM ports on a Atmega 2560...
If each Delta needs individual data, you have to find a way to rename the axis' of the slave Delta, so they can sort out their relevant data themselves.

; Master = X Y Z E1 E2
; Slave = A B C U V
G1 F.... X*  Y* Z* E1* E2* A* B* C* U* V*

You would still need a handshake signal between both controller to be sure they work synchronuosly on the same line of code.
