Communication with VFD over RS485

Capturing some rough thoughts:

• controller board would need to support multi-drop (selectable termination)
• python software could have on/off/speed selector
• ui picker for part and cutter materials could do surface speed calculations (this works on both lathe and mill). cutter material could be saved in tool table.
• lathe-focused: we could adjust speed "continuously" based on what the readout for part dia is

I'm also personally interested in making this work with some older servo drives (Parker Aries, Teknic SST) that don't speak RS485, but have either a +/-10v analog + digital run signal, or take step/dir. This would take a pretty trivial adapter board once we figure out who handles the acceleration ramps.
