Taking serial control of my spindle!  

Ok, so, here is a fast moving video of me at ~2:AM after getting a test wire up to work on my CNC 6040's .8KW spindle responding to a serial rig-up using an IC-485S serial converter between my PC's RS-232 and the spindles 1.5KW VFD inverter via a (custom speaker wire :) twisted pair for a "point-to-point" two wire half duplex RS-485 serial connection!

Oh man, I gotta go to bed...  More rigging tomorrow!
