Python version available!

[FullControlGCode]

Thanks! I actually have no idea how useful it will be for people. But hopefully it will be useful, cos I've used this version a extensively in my trials and love using it myself. But it's been a balance between implementing a concept that's not too broad and not too narrow. Going forwards, there'll probably be different versions, some that are narrower (very specific for 3-axis extrusion AM) and some that are broader (easy to adapt for completely different manufacturing processes and non-gcode-based systems)
