I have plans for building a CNC router down the road and was planning on using a Raspberry PI/Arduino Combo for controlling the CNC and be able to access it via web browser as well as a TFT touch screen with GUI for manual controls to hopefully be built into a standalone unit that doesn't require an external PC to be physically tied up to it. Probably won't make it on, but was curious to see your take on such a project. My funds limit my projects, so being able to see other builds in this manner done is great inspiration for what to expect when I can finally do this myself.
