I was convinced to try a smoothieboard as controller for an Openbuilds OX CNC 1500x1000mm. The USB connection is impacted by noise so I'm using the ethernet interface (one of the main reasons for me to use the smoothie)
On a CNC we have different UI needs than a 3D printer, so I've modified the standard webUI, creating a custom one dedicated to 3 axis CNC including Zeroing axis, XYZ position feedback and position override. I also added a confirm for the Play link before starting file playback. Is anyone out there interested in a copy?
