I'm making good progress on adding some new features, including support for gcode file downloads. I'm spending a fair amount of time changing the UI to make better use of a tablet-size display where available. To avoid a lot of duplicated code, this means expanding on the use of Fragments, and moving as much code as possible within them or related support libraries.
I'm also continuing to look at gcode generation options. So far, CamBam seems to be the most reliable option, but I'm also still trying out HeeksCAM.
Another video when I have time to put together a real demo.
