Hi I am in the process of trying something that will help me cut on the chop saw easy.I really need help making a gcode sender that will move the axis to desired location. see image below. I would like to use a raspberypi with touchscreen to display this layout.
You want to look into a Python library called Kivy. It should allow you to implement this and works with both Raspbian and the Raspberry Pi official touch screen. As an aside, one nice thing it does is provide touch keyboards/keypads. So you could simplify your interface by just having a desired position field that when you tap bring up a keypad overlay.
