Hi,
I use Screen2010, and sometimes I write short G-code on it.
But, the written G-code has to be saved once with a file name, then you have to open it.
So that, if you make a file beforehand with some wards, you load it and call editor from the screen.
Screen2010 has an icon to call the text editor.
I do not know if 1024set can call the text editor from the screen.
By this way, you can see immediately what will happen when you add or alter G-code.
I hope I do not guess wrong ...
